Declarations of War and Authorizations for the Use of Military Force

Summary
From the Washington Administration to the present, Congress and the President have enacted 11
separate formal declarations of war against foreign nations in five different wars. Each
declaration has been preceded by a presidential request either in writing or in person before a
joint session of Congress. The reasons cited in justification for the requests have included armed
attacks on United States territory or its citizens and threats to United States rights or interests as a
sovereign nation.
Congress and the President have also enacted authorizations for the use of force rather than
formal declarations of war. Such measures have generally authorized the use of force against
either a named country or unnamed hostile nations in a given region. In most cases, the President
has requested the authority, but Congress has sometimes given the President less than what he
asked for. Not all authorizations for the use of force have resulted in actual combat. Both
declarations and authorizations require the signature of the President in order to become law.
In contrast to an authorization, a declaration of war in itself creates a state of war under
international law and legitimates the killing of enemy combatants, the seizure of enemy property,
and the apprehension of enemy aliens. While a formal declaration was once deemed a necessary
legal prerequisite to war and was thought to terminate diplomatic and commercial relations and
most treaties between the combatants, declarations have fallen into disuse since World War II.
The laws of war, such as the Hague and Geneva Conventions, apply to circumstances of armed
conflict whether or not a formal declaration or authorization was issued.
With respect to domestic law, a declaration of war automatically triggers many standby statutory
authorities conferring special powers on the President with respect to the military, foreign trade,
transportation, communications, manufacturing, alien enemies, etc. In contrast, no standby
authorities appear to be triggered automatically by an authorization for the use of force, although
the executive branch has argued, with varying success, that the authorization to use force in
response to the terrorist attacks of 2001 provided a statutory exception to certain statutory
prohibitions.
Most statutory standby authorities do not expressly require a declaration of war to be actualized
but can be triggered by a declaration of national emergency or simply by the existence of a state
of war; however, courts have sometimes construed the word “war” in a statute as implying a
formal declaration, leading Congress to enact clarifying amendments in two cases. Declarations
of war and authorizations for the use of force waive the time limitations otherwise applicable to
the use of force imposed by the War Powers Resolution.
This report provides historical background on the enactment of declarations of war and
authorizations for the use of force and analyzes their legal effects under international and
domestic law. It also sets forth their texts in two appendices. The report includes an extensive
listing and summary of statutes that are triggered by a declaration of war, a declaration of national
emergency, and/or the existence of a state of war. The report concludes with a summary of the
congressional procedures applicable to the enactment of a declaration of war or authorization for
the use of force and to measures under the War Powers Resolution. The report will be updated as
circumstances warrant.

Declarations of War and Authorizations for the Use of Military Force

Introduction
Article I, § 8, of the Constitution vests in Congress the power “to declare War.” Pursuant to that
power, Congress has enacted 11 declarations of war during the course of American history
relating to five different wars, the most recent being those that were adopted during World War II.
In addition, Congress has adopted a number of authorizations for the use of military force, the
most recent being the joint resolution enacted on October 16, 2002, authorizing the use of
military force against Iraq. To buttress the nation’s ability to prosecute a war or armed conflict,
Congress has also enacted numerous statutes which confer standby authority on the President or
the executive branch and are activated by the enactment of a declaration of war, the existence of a
state of war, or the promulgation of a declaration of national emergency.
This report examines a number of topics related to declarations of war and authorizations for the
use of military force by the United States. It (1) provides historical background on each of the
declarations of war and on several major authorizations for the use of force that have been
enacted; (2) analyzes the implications of declarations of war and authorizations for the use of
force under both international law and domestic law; (3) lists and summarizes the more than 250
standby statutory authorities that can come into effect pursuant to a declaration of war, the
existence of a state of war, and/or a declaration of national emergency; (4) describes the
procedures in Congress governing the consideration of declarations of war and authorizations for
the use of force, including the procedures under the War Powers Resolution; and (5) sets forth in
two appendices the texts of all of the declarations of war and the major authorizations for the use
of force that have been enacted. The report does not address the issue of the constitutionality of
Presidential uses of military force absent a declaration of war or authorization for the use of force.
The report will be updated as circumstances warrant.
Previous Declarations of War
From the Washington Administration to the present, there have been 11 separate formal
declarations of war against foreign nations enacted by Congress and the President, encompassing
five different wars—the War of 1812 with Great Britain, the War with Mexico in 1846, the War
with Spain in 1898, the First World War, and the Second World War.1 In each case the enactment
of a formal declaration of war has been preceded by a presidential request to Congress for such an
action, either in writing or in person before a joint session of Congress. In each such message
requesting a war declaration, the President has cited what he deemed compelling reasons for
doing so. These reasons have included armed attacks on United States territory or its citizens, and
attacks on or direct threats to United States rights or interests as a sovereign nation. In the
nineteenth century all declarations of war were passed by the Congress in the form of a bill. In the
twentieth century all declarations of war were passed by the Congress in the form of a joint
resolution. In every instance the measures were adopted by majority vote in both the House and
the Senate and were signed into law by the President.2 The last formal declaration of war was
enacted on June 5, 1942, against Rumania during World War II.3

States. See Appendix A for the texts of these declarations.

timing of presidential requests for war declarations. Those matters have been the subject of important debates among

Declarations of War and Authorizations for the Use of Military Force

The circumstances of President McKinley’s request for a declaration of war against Spain in 1898
stand in singular contrast to all the others. McKinley’s request for a declaration of war on April
25, 1898, was approved by a voice vote of both Houses of Congress on that date. His request was
made after Spain had rejected a U.S. ultimatum that Spain relinquish its sovereignty over Cuba
and permit Cuba to become an independent state. This ultimatum was supported by a joint
resolution of Congress, signed into law on April 20, 1898, that among other things, declared Cuba
to be independent, demanded that Spain withdraw its military forces from the island, and directed
and authorized the President to use the U.S. Army, Navy and militia of the various states to
achieve these ends. The war with Spain in 1898, in short, was not principally based on attacks on
the United States but on a U.S. effort to end the Cuban insurrection against Spain, bring about
Cuban independence, and restore a stable government and order on the island—outcomes that
were believed by the United States to advance its interests.4
In the twentieth century, without exception, presidential requests for formal declarations of war
by Congress were based on findings by the President that U.S. territory or sovereign rights had
been attacked or threatened by a foreign nation. Although President Wilson had tried to maintain
U.S. neutrality after the outbreak of the First World War, he regarded the German decision on
February 1, 1917, to engage in unrestricted submarine warfare against all naval vessels in the war
zone, including those of neutral states, to be an unacceptable assault on U.S. sovereign rights
which the German Government had previously pledged to respect. Wilson’s request to Congress
for a declaration of war against Germany on April 2, 1917, stated that war had been “thrust upon
the United States” by Germany’s actions. Congress passed a joint resolution declaring war which
the President signed on April 6, 1917. Wilson delayed requesting a war declaration against
Austria-Hungary until December 4, 1917. He did so then because that state, a German ally in the
war, had become an active instrument of Germany against the United States. Congress quickly
passed a joint resolution declaring war which the President signed on December 7, 1917.5
President Franklin D. Roosevelt requested a declaration of war against Japan on December 8,
1941, because of direct military attacks by that nation against U.S. territory, military personnel
and citizens in Hawaii and other outposts in the Pacific area. The House and the Senate passed the
requested declaration and the President signed it into law that same day. After Germany and Italy
each declared war on the United States on December 11, 1941, President Roosevelt asked
Congress to respond in kind by recognizing that a state of war existed between the United States

and those two nations. Congress passed separate joint resolutions declaring war on both nations
which the President signed on December 11, 1941.6 On June 2, 1942, President Roosevelt asked
that Congress declare war on Bulgaria, Hungary and Rumania, nations that were under the
domination of Germany, were engaged in active military actions against the United States, and
had themselves declared war on the United States. Congress passed separate joint resolutions
declaring war on each of these nations. The President signed these resolutions on June 5, 1942.7
There is a striking similarity of language in the eight declarations of war passed by the Congress
in the twentieth century. They all declare that a “state of war” exists between the United States
and the other nation. With the one exception of the declaration of war against Austria-Hungary on
December 7, 1917, the other seven declarations characterize the state of war as having been
“thrust upon the United States” by the other nation. All eight of these twentieth century
declarations of war state in identical language that the President is—
authorized and directed to employ the entire naval and military forces of the United States
and the resources of the Government to carry on war against [the ‘Government’ of the
particular nation]; and to bring the conflict to a successful termination all of the resources of
the country are hereby pledged by the Congress of the United States.

Declarations of War and Authorizations for the Use of Military Force

Key Statutory Authorizations for the Use of
Military Force

From the Administration of President John Adams to the present, there have been various
instances when legislation has been enacted authorizing the use of military force by the President
instead of formally declaring war. In most cases such legislation has been preceded by a specific
request by the President for such authority. During the Presidencies of John Adams and Thomas
Jefferson, these Chief Executives noted in messages to Congress that Congressional
authorizations for use of force would be appropriate to enable the United States to protect its
interests from predatory actions by foreign powers, in particular attacks on U.S. commercial
vessels and persons on the high seas by France and by Tripoli. Congress responded with specific
authorizations for the use of force under the President’s direction in 1798 against France and in
1802 against Tripoli. In 1815 President James Madison formally requested that Congress declare
war against the Regency of Algiers in response to its attacks on U.S. citizens and commerce in the
Mediterranean. Congress responded with an act authorizing the President to utilize U.S. armed
vessels to be used against Algerian naval attacks but did not declare war.
In the period following World War II, Presidential requests for authority to use military force,
when made, have usually been for broad authority to use U.S. military force in a specific region
of the world in order to defend U.S. interests or friendly states as the President deems appropriate.
More recently, due to an expansive interpretation of the President’s constitutional authority as
Commander-in-Chief of the Armed Forces and of his inherent powers to use force without
Congressional authorization, the President has welcomed support from the Congress in the form
of legislation authorizing him to utilize U.S. military forces in a foreign conflict or engagement in
support of U.S. interests, but has not taken the view that he is required to obtain such
authorization.
What follows is a brief overview of key legislative authorizations of the use of military force by
the President from the Administration of John Adams to the present.8 Appendix B provides the
complete text of these specific authorizations.
France 1798
The United States during the 1790s had remained neutral in the conflict in Europe between
France and Great Britain and had only begun to develop a Navy. During the Administration of
President John Adams, relations with France deteriorated as American commercial ships were
frequently seized by French naval vessels. In response, in his message to Congress on May 16,
1797, President Adams argued that it would be prudent for the Congress to enact legislation that
would address the actions of the French by authorizing, among other things, the use of U.S. naval
vessels to defend against attacks on American shipping and citizens engaged in lawful commerce

8 There have been numbers of scholarly works written that address, in depth, the circumstances surrounding most of the
measures discussed herein. It is beyond the scope of this report to itemize fully the complex diplomatic, political and
military motivations that led to their enactment. For general background see Bemis, Samuel Flagg , A Diplomatic

abroad. President Adams reiterated, in a message of March 19, 1798, his view of the necessity for
Congressional action on his recommendations for the adoption of measures to protect American
seafaring citizens and commerce.9
Congress subsequently responded to the President’s recommendations by passing legislation
“more effectually to protect the Commerce and Coasts of the United States” authorizing the
President to instruct commanders of U.S. armed vessels to act against any “armed vessel” found
to have committed or attempting to commit “depredations on the vessels” belonging to United
States citizens, and to retake any ship or vessel of United States citizens that may have been
captured by non-U.S. armed vessels.10 The legislation was signed into law on May 28, 1798,
Congress passed additional legislation, signed into law on July 9, 1798, that authorized the
President to instruct commanders of U.S. Navy warships to “subdue, seize and take any armed
French vessel which shall be found within the jurisdictional limits of the United States, or
elsewhere, on the high seas....” The President was further granted the authority to grant special
commissions to “owners of private armed ships and vessels of the United States,” to permit them
to lawfully subdue, seize, and capture “any armed French vessel,” and to recapture U.S. vessels,
goods and effects of U.S. citizens with the same authority as U.S. Navy vessels, subject to
instructions given by the President.11
Tripoli 1802
President Thomas Jefferson, in response to attacks on U.S. commercial shipping in the
Mediterranean Sea by vessels under the control of the Bey of Tripoli, noted in his message to
Congress of December 8, 1801, that it would be prudent for Congress to authorize the use of U.S.
Navy forces to protect U.S. shipping against Tripoli, including permitting them to take offensive
action against Tripolitan vessels.12 Congress responded by passing legislation, enacted on
February 6, 1802, that authorized the President to “equip, officer, man, and employ such of the
armed vessels of the United States as may be judged requisite by the President of the United
States, for protecting effectually the commerce and seamen thereof on the Atlantic ocean, the
Mediterranean and adjoining seas.” The President was also authorized to utilize the U.S. Navy “to
subdue, seize and make prize of all vessels, goods and effects belonging to the Bey of Tripoli, or
his subjects ... and to cause to be done all such other acts of precaution or hostility as the state of
war will justify, and may, in his opinion, require.” The President was further granted the authority
to grant special commissions to “owners of private armed vessels of the United States,” to permit
them to lawfully subdue and seize “any Tripolitan vessel, goods or effects” with the same
authority as U.S. Navy vessels, subject to instructions given by the President.13

Declarations of War and Authorizations for the Use of Military Force

Algeria 1815
President James Madison, after the conclusion of a peace treaty with Great Britain ending the War
of 1812, sought authority to use the U.S. Navy to take action against vessels of the ruler and
Regency of Algeria that had been seizing U.S. commercial vessels in the Mediterranean area. Due
to acts of “overt and direct warfare against the citizens of the United States,” President Madison,
on February 23, 1815, recommended that Congress declare the “existence of a state of war
between the United States and the Dey and Regency of Algiers.”14 Congress did not declare war
but did pass legislation, enacted on March 3, 1815, that authorized the President to use the U.S.
Navy, “as judged requisite by the President” to protect the “commerce and seamen” of the United
States on the “Atlantic Ocean, the Mediterranean and adjoining seas.” The President was also
authorized to utilize the U.S. Navy to seize “all vessels, goods and effects belonging to the Dey of
Algiers, or to his subjects ... and to cause to be done all such other acts of precaution or hostility
as the state of war will justify, and may, in his opinion, require.” The President was further
granted the discretionary authority to grant special commissions to “owners of private armed
vessels of the United States,” to permit them to lawfully subdue, seize, and capture “any Algerine
vessel, goods or effects” with the same authority as U.S. Navy vessels, subject to instructions
given by the President.15
Suppression of Piracy 1819-1823
During the years after the War of 1812, there was a notable increase in the number of attacks on
U.S. commercial shipping vessels in and around the Caribbean and Latin American coastal
waters. Some of this was stimulated by the chaotic conditions attendant to the struggles for
independence by South American colonies of Spain. Pirates attacked not only Spanish vessels in
the region, but vessels of other nations generally. In response to calls for action against these
predatory attacks on their vessels, American shippers petitioned Congress for action to protect
them from pirates. In response, on March 3, 1819, legislation was enacted “to protect the
commerce of the United States, and punish the crime of piracy.” This legislation authorized the
President to employ “the public armed vessels” of the United States as he deemed necessary to
protect “the merchant vessels of the United States and their crews from piratical aggressions and
depredations.” This legislation further authorized the President to instruct the commanders of the
“public armed vessels of the United States” to take various actions to combat piracy, including
attacking and seizing pirates and their vessels. The legislation also authorized U.S. vessels
attacked by pirates to take actions against their aggressors and seize their ships. The legislation
further established penalties for those that engaged in piracy. This 1819 statute was subsequently
made permanent law on January 30, 1823. It has been amended, but the current text, found in
Title 33 of the United States Code, contains substantially the same language as was enacted in
March of 1819.16

Formosa 1955
In a message to Congress on January 24, 1955, President Dwight Eisenhower, detailed a series of
“provocative political and military actions” by the Chinese Communist government that he
believed established a “pattern of aggressive purpose.” That purpose was the “conquest of
Formosa.” This situation, said Eisenhower, posed a “serious danger to the security of our country
and of the entire Pacific area and indeed to the peace of the world.” The President believed that
the U.S. should not wait for the United Nations to take steps to deal with the situation but should
be prepared to use its own armed forces “to assure the security of Formosa and the Pescadores.”
President Eisenhower stated that authority for “some of the actions which might be required
would be inherent in the authority of the Commander-in-Chief.” He noted that, pending
Congressional action, he “would not hesitate, so far as my Constitutional powers extend, to take
whatever emergency action might be forced upon us to protect the rights and security of the
United States.” However, he stated that a “suitable Congressional resolution would clearly and
publicly establish the authority of the President as Commander-in-Chief to employ” the U.S.
armed forces “promptly and effectively” as he deemed necessary to deal with the circumstances.
Such a resolution would “make clear the unified and serious intentions of our Government, our
Congress and our people.”17
In response to the President’s request, Congress passed legislation on January 29, 1955, that
authorized the President to “employ the Armed Forces of the United States as he deems necessary
for the specific purpose of securing and protecting Formosa, and the Pescadores against armed
attack....” The President was also authorized to take “such other measures as he judges to be
required or appropriate in assuring the defense of Formosa and the Pescadores.” The resolution
stated that it would expire when the President determined and reported to Congress that the
“peace and security of the area is reasonably assured....”18 The resolution was subsequently
repealed in 1974.19
Middle East 1957
In a special message to Congress on January 5, 1957, President Dwight D. Eisenhower requested
Congressional support for a program of military and economic cooperation with nations in the
general area of the Middle East to “deal with the possibility of Communist aggression, direct or
indirect” against nations in that region. As one component of this military and economic
assistance program, President Eisenhower sought authority to employ the “armed forces of the
United States to secure and protect the territorial integrity and political independence of such
nations, requesting such aid, against overt armed aggression from any nation controlled by
International Communism.” The President emphasized that such authority would not be utilized
by him “except at the desire of the nation attacked.”20

Declarations of War and Authorizations for the Use of Military Force

In response, the Congress passed legislation, enacted on March 9, 1957, that, among other things,
authorized the President “to undertake, in the general area of the Middle East, military assistance
programs with any nation or group of nations of that area desiring such assistance.” The joint
resolution further provided that “if the President determines the necessity thereof, the United
States is prepared to use armed forces to assist any such nation or group of such nations
requesting assistance against armed aggression from any country controlled by international
communism: Provided, that such employment shall be consonant with the treaty obligations of
the United States and with the Constitution of the United States.” The President was also to report
to Congress on his action under the joint resolution between January and July of each year. The
joint resolution further provided that it would expire when the President determined that the
“peace and security of the nations in the general area of the Middle East” was “reasonably
assured” or should Congress terminate it earlier by passage of a concurrent resolution.21 The
resolution has not been formally repealed.22
Southeast Asia 1964
In the early 1960s the United States had been providing military assistance and support to the
government of South Vietnam. Over time tensions, associated with the U.S. military presence in
Southeast Asia and support for the South Vietnamese government, grew between the U.S. and the
communist government of North Vietnam. On August 2, 1964, a U.S. destroyer, the U.S.S.
Maddox, while in international waters off the coast of North Vietnam (the Gulf of Tonkin) was
attacked by North Vietnamese torpedo boats. The attack was repulsed. The State Department
protested to the North Vietnamese government and noted that grave consequences would follow
additional offensive actions against U.S. forces. Subsequently, on August 4, further attacks by
North Vietnamese vessels against U.S. destroyers were reported to Washington. President Lyndon
Johnson responded on August 4 by sending U.S. military aircraft to bomb “gunboats and certain
supporting facilities” in North Vietnam that had allegedly been used in the actions against U.S.
naval vessels. After meeting with Congressional leaders, President Johnson on August 5, 1964,
formally requested a resolution of Congress that would “express the support of the Congress for

Services, in a joint report, noted that in considering the legislation various strongly held views had been “vigorously
expressed” regarding the constitutional powers of the President and of the Congress, as well as the proper constitutional
procedure to be followed in the situation contemplated by the legislation. The final legislative language adopted
reflected this debate. This language had, the Senate committees said, “the virtue of remaining silent on the question of
the relationship between the Congress and the President with respect to the use of the Armed Forces for the objectives
stated in the resolution.” The Senate committees also argued that although there was sharp division as to the “proper
constitutional processes” to follow in support of the President’s request, there was none regarding the substantive
policy involved. They stated that “the clear statement of policy in section 2 of the resolution as reported is preferable to
a blanket authorization to the President to use the Armed Forces in this area.” U.S. Congress. Senate. Committees on

all necessary action to protect our armed forces and to assist nations covered by the SEATO
Treaty.”23
Congress responded to President Johnson’s request by passing a joint resolution to “promote the
maintenance of international peace and security in southeast Asia.” This legislation has come to
be popularly known as the “Gulf of Tonkin resolution.” This joint resolution, enacted on August
10, 1964, stated that “the Congress approves and supports the determination of the President, as
Commander-in-Chief, to take all necessary measures to repel any armed attack against the forces
of the United States and to prevent further aggression.” The joint resolution further stated that
“[c]onsonant with the Constitution of the United States and the Charter of the United Nations and
in accordance with its obligations under the Southeast Asia Collective Defense Treaty, the United
States is, therefore, prepared, as the President determines, to take all necessary steps, including
the use of armed force, to assist any member or protocol state of the Southeast Asia Collective
Defense Treaty requesting assistance in defense of its freedom.” The joint resolution stated that it
would expire whenever the President determined that the “peace and security of the area is
reasonably assured” or if Congress chose to terminate it earlier by concurrent resolution.24
Congress repealed the resolution in 1971.25
Lebanon 1983
On July 6, 1982, President Ronald Reagan announced he would send a small contingent of U.S.
troops to participate in a multinational force for temporary peacekeeping in Lebanon. When the
forces began to land on August 25, President Reagan reported this action to Congress but did not
cite section 4(a)(1) of the War Powers Resolution,26 and said the agreement with Lebanon ruled
out any combat responsibilities. After overseeing the departure of the Palestine Liberation
Organization force, the U.S. Marines in the first Multinational Force left Lebanon on September
10, 1982. The second dispatch of Marines to Lebanon began on September 20, 1982. President
Reagan announced that the United States, France, and Italy had agreed to form a new
multinational force to return to Lebanon for a limited period of time to help maintain order until
the lawful authorities in Lebanon could discharge those duties. The action followed three events
that took place after the withdrawal of the first group of U.S. Marines: the assassination of
Lebanon President-elect Bashir Gemayel, the entry of Israeli forces into West Beirut, and the
massacre of Palestinian civilians by Lebanese Christian militiamen.
On September 29, 1982, President Reagan submitted a report to Congress that 1,200 Marines had
begun to arrive in Beirut, but again he did not cite section 4(a)(1), of the War Powers Resolution,
stating that the American force would not engage in combat. As a result of incidents in which
U.S. Marines were killed or wounded, there was controversy in Congress on whether the
President’s report should have been filed under section 4(a)(1). In mid-1983 Congress passed the
Lebanon Emergency Assistance Act of 1983 requiring statutory authorization for any substantial

expansion in the number or role of U.S. Armed Forces in Lebanon. It also included a section that
stated:
Nothing in this section is intended to modify, limit, or suspend any of the standards and
procedures prescribed by the War Powers Resolution of 1973.27
President Reagan reported on the Lebanon situation again on August 30, 1983, still not citing
section 4(a)(1), after fighting broke out between various factions in Lebanon and two Marines
were killed. The level of fighting heightened; and as the Marine casualties increased and the
action enlarged, there were more calls in Congress for invocation of the War Powers Resolution.
Several Members of Congress said the situation had changed since the President’s first report and
introduced legislation that took various approaches. Senator Charles Mathias introduced S.J.Res.
159 stating that the time limit specified in the War Powers Resolution had begun on August 31,
1983, and authorizing the forces to remain in Lebanon for a period of 120 days after the
expiration of the 60-day period. Representative Thomas Downey introduced H.J.Res. 348
directing the President to report under section 4(a)(1) of the War Powers Resolution. Senator
Robert Byrd introduced S.J.Res. 163 finding that section 4(a)(1) of the War Powers Resolution
applied to the present circumstances in Lebanon. The House Appropriations Committee approved
an amendment to the continuing resolution for FY1984 (H.J.Res. 367), sponsored by
Representative Clarence Long, providing that after 60 days, funds could not be “obligated or
expended for peacekeeping activities in Lebanon by United States Armed Forces,” unless the
President had submitted a report under section 4(a)(1) of the War Powers Resolution. A similar
amendment was later rejected by the full body, but it reminded the Administration of possible
congressional actions.
On September 20, 1983, congressional leaders and President Reagan agreed on a compromise
resolution invoking section 4(a)(1) of the War Powers Resolution and authorizing the Marines to
remain for 18 months. The Multinational Force in Lebanon Resolution became the first
legislation to be handled under the expedited procedures of the War Powers Resolution. On
September 28 the House passed H.J.Res. 364 by a vote of 270 to 161. On September 29 the
Senate passed S.J.Res. 159 by a vote of 54 to 46. The House accepted the Senate bill by a vote of
253 to 156 later the same day. The President signed the joint resolution into law on October 12,
1983. As passed, the joint resolution contained four occurrences that would terminate the
authorization before eighteen months: (1) the withdrawal of all foreign forces from Lebanon,
unless the President certified continued U.S. participation was required to accomplish specified
purposes; (2) the assumption by the United Nations or the Government of Lebanon of the
responsibilities of the Multinational Force; (3) the implementation of other effective security
arrangements; or (4) the withdrawal of all other countries from participation in the Multinational
Force. Congress also determined in the joint resolution that the requirements of section 4(a)(1) of
the War Powers Resolution became operative on August 29, 1983.28
In a statement made on signing S.J.Res. 159 on October 12, 1983, President Reagan expressed
appreciation for the support for the U.S. presence and policies in Lebanon he believed were
embodied in the legislation. He sharply differed, however, with various “findings, determinations,
and assertions” by the Congress on certain matters. He stated his concerns about the practical
problems associated with section 4(a)(1) of the War Powers Resolution, and the wisdom and

constitutionality of section 5(b). President Reagan noted that in signing the Lebanon resolution it
was important for him to state
that I do not and cannot cede any of the authority vested in me under the Constitution as
President and as Commander in Chief of United States Armed Forces. Nor should my
signing be viewed as any acknowledgment that the President’s constitutional authority can
be impermissibly infringed by statute, that congressional authorization would be required if
and when the period specified in section 5(b) of the War Powers Resolution might be
deemed to have been triggered and the period had expired, or that section 6 of the
Multinational Force in Lebanon Resolution may be interpreted to revise the constitutional
authority to deploy United States Armed Forces.29
Iraq 1991
On August 2, 1990, Iraqi troops under the direction of President Saddam Hussein invaded
Kuwait, seized its oil fields, installed a new government in Kuwait City, and moved toward the
border with Saudi Arabia. A week after the invasion, on August 9, President George H.W. Bush
reported to Congress “consistent with the War Powers Resolution” that he had deployed U.S.
armed forces to the region prepared to take action with others to deter further Iraqi aggression. He
noted that he did not believe involvement in hostilities was imminent. Throughout the rest of
1990, President Bush continued to work to establish an international coalition opposed to Iraq’s
aggression, while continuing to deploy additional U.S. military reinforcements into Saudi Arabia
and the Persian Gulf region. By the end of the year approximately 350,000 U.S. forces had been
deployed to the area.30
As the prospect of a war without congressional authorization increased, on November 20, 1990,
Representative Ron Dellums and 44 other Democratic Members of Congress sought a judicial
order enjoining the President from offensive military operations in connection with Operation
Desert Shield unless he consulted with and obtained an authorization from Congress. On
December 13, Judge Harold Greene of the federal district court in Washington, D.C. denied the
injunction, holding that the controversy was not ripe for judicial resolution because a majority of
Congress had not sought relief and the executive branch had not shown sufficient commitment to
a definitive course of action.31
By January, 1991, President Bush had secured the support of the United Nations and an
international coalition to use force, if necessary, to free Kuwait from Iraqi occupation. U.N.
Resolution 678 of November 29, 1990, authorized all U.N. member states “to use all necessary
means” to implement various U.N. resolutions seeking to end Iraqi occupation of Kuwait. It set a
January 15, 1991 deadline for Iraq to implement fully all relevant U.N. resolutions relating to its
invasion of Kuwait. On January 8, 1991, President George H.W. Bush, in a letter to the

suicide truck bombing, raising fresh questions in Congress and U.S. public opinion about U.S. participation in the
Lebanon peacekeeping endeavor. On February 7, 1984, President Reagan announced the Marines would be redeployed
and on March 30, 1984, reported to Congress that U.S. participation in the Multinational Force in Lebanon had ended.

congressional leaders, requested a congressional resolution supporting the use of all necessary
means to implement U.N. Security Council Resolution 678. He stated that he was “determined to
do whatever is necessary to protect America’s security” and that he could “think of no better way
than for Congress to express its support for the President at this critical time.” It is noteworthy
that the President’s request for a resolution was a request for congressional “support” for his
undertaking in the Persian Gulf, not for “authority” to engage in the military operation. In a press
conference on January 9, 1991, President Bush reinforced this distinction in response to questions
about the use of force resolution being debated in Congress. He was asked whether he thought he
needed the resolution, and if he lost on it would he feel bound by that decision. President Bush in
response stated: “I don’t think I need it .... I feel that I have the authority to fully implement the
United Nations resolutions.” He added that he felt that he had “the constitutional authority—
many attorneys having so advised me.”32
On January 12, 1991, both houses passed the “Authorization for Use of Military Force Against
Iraq Resolution.” Section 2(a) of that joint resolution authorized the President to use U.S. Armed
Forces pursuant to U.N. Security Council Resolution 678 to achieve implementation of the earlier
Security Council resolutions. Section 2(b) required as a precondition that the President would first
have to report to Congress that the United States had used all appropriate diplomatic and other
peaceful means to obtain compliance by Iraq with the Security Council resolution and that those
efforts had not been successful. Section 2(c) stated that it constituted specific statutory
authorization within the meaning of Section 5(b) of the War Powers Resolution. Section 3
required the President to report every 60 days on efforts to obtain compliance of Iraq with the
U.N. Security Council resolution.33
On signing H.J.Res. 77 into law, President Bush said the following:
As I made clear to congressional leaders at the outset, my request for congressional support
did not, and my signing this resolution does not, constitute any change in the long-standing
positions of the executive branch on either the President’s constitutional authority to use the
Armed Forces to defend vital U.S. interests or the constitutionality of the War Powers
Resolution.
He added that he was pleased that “differences on these issues between the President and many in

President Bush made the determination required by P.L. 102-1 that diplomatic means had not and
would not compel Iraq to withdraw from Kuwait. On January 18, he reported to Congress

Terrorist Attacks against the United States (World Trade Center and
the Pentagon) 2001

On September 11, 2001, terrorists hijacked four U.S. commercial airliners, crashing two into the
twin towers of the World Trade Center in New York City, and another into the Pentagon building
in Arlington, Virginia. The fourth plane crashed in Shanksville, Pennsylvania near Pittsburgh,
after passengers struggled with the highjackers for control of the aircraft. The death toll from
these incidents was nearly 3,000. President George W. Bush characterized these attacks as more
than acts of terror. “They were acts of war,” he said. He added that “freedom and democracy are
under attack,” and he asserted that the United States would use “all of our resources to conquer
this enemy.”36
In the days immediately after the September 11 attacks, the President consulted with the leaders
of Congress on appropriate steps to take to deal with the situation confronting the United States.
One of the things that emerged from discussions was the concept of a joint resolution of the
Congress authorizing the President to take military steps to deal with the parties responsible for
the attacks on the United States. Between September 13 and 14, draft language of such a
resolution was discussed and negotiated by the President’s representatives and the House and
Senate leadership of both parties. Other members of both Houses suggested language for
consideration. On Friday, September 14, 2001, the text of a joint resolution was introduced. It was
first considered and passed by the Senate in the morning of September 14, as Senate Joint
Resolution 23, by a vote of 98-0. The House of Representatives passed it later that evening, by a
vote of 420-1, after tabling an identical resolution, H.J.Res. 64, and rejecting a motion to
recommit by Representative John Tierney that would have had the effect, if passed and enacted,
of requiring a report from the President on his actions under the resolution every 60 days.37
President Bush signed the measure into law on September 18, 2001.38 The joint resolution
authorizes the President
to use all necessary and appropriate force against those nations, organizations, or persons he
determines planned, authorized, committed, or aided the terrorist attacks that occurred on
September 11, 2001, or harbored such organizations or persons, in order to prevent any
future acts of international terrorism against the United States by such nations, organizations
or persons.

Declarations of War and Authorizations for the Use of Military Force

The joint resolution further states that Congress declares that this resolution is intended to
“constitute specific statutory authorization within the meaning of section 5(b) of the War Powers
Resolution.” Finally, the joint resolution also states that “[n]othing in this resolution supersedes
any requirement of the War Powers Resolution.”
A notable feature of P.L. 107-40 is that, unlike all other major legislation authorizing the use of
military force by the President, this joint resolution authorizes military force against not only
nations but also organizations and persons linked to the September 11, 2001, attacks on the
United States. This authorization of military action against organizations and persons is
unprecedented in American history, with the scope of its reach yet to be determined. The
authorization of use of force against unnamed nations is more consistent with some previous
instances where authority was given to act against unnamed states as appropriate when they
became aggressors or took military action against the United States or its citizens.
President George W. Bush in signing S.J.Res. 23 on September 18, 2001, stated that the Congress
had acted “wisely, decisively, and in the finest traditions of our country.” He thanked the
“leadership of both Houses for their role in expeditiously passing this historic joint resolution.”
He noted that he had had the “benefit of meaningful consultations with members of the Congress”
since the September 11 attacks and that he would “continue to consult closely with them as our
Nation responds to this threat to our peace and security.” President Bush also asserted that
S.J.Res. 23 “recognized the authority of the President under the Constitution to take action to
deter and prevent acts of terrorism against the United States.” He also stated that “in signing this
resolution, I maintain the longstanding position of the executive branch regarding the President’s
constitutional authority to use force, including the Armed Forces of the United States, and
regarding the constitutionality of the War Powers Resolution.”39
The Bush Administration interpreted P.L. 107-40 broadly, to confirm the President’s authority as
Commander-in-Chief to conduct antiterrorism operations anywhere in the world, including within
the United States.40 In 2004, the Supreme Court affirmed the President’s powers to detain “enemy
combatants” captured in Afghanistan as part of the necessary force authorized by Congress, but
found that detainees could challenge their detention in federal court.41 In light of the Supreme
Court decisions, the Bush Administration interpreted the joint resolution to authorize any
measures that can be characterized as fundamental incidents of the conduct of war, even where
such measures are otherwise prohibited by statute (at least so long as the statute in question
contemplates a statutory exception). Thus, the Administration cited the joint resolution to support
the President’s power to detain persons he has deemed to be “enemy combatants” (whether
citizens or aliens and without regard to the location or circumstances of their capture)42 and to
conduct electronic surveillance of communications within the United States without following the

combatants for violations of the law of war.44
Authorization for Use of Force Against Iraq 2002
In the summer of 2002, the Bush Administration made public its views regarding what it deemed
a significant threat to U.S. interests and security posed by the prospect that Iraq had or was
acquiring weapons of mass destruction. Senior members of the Bush Administration cited a
number of violations of U.N. Security Council resolutions by Iraq regarding the obligation
imposed at the end of the Gulf War in 1991 to end its chemical, biological and nuclear weapons
programs. On September 4, 2002, President Bush met with leaders from both Houses and parties
at the White House. At that meeting the President stated that he would seek Congressional
support, in the near future, for action deemed necessary to deal with the threat posed to the United
States by the regime of Saddam Hussein of Iraq. The President also indicated that he would speak
to the United Nations shortly and set out his concerns about Iraq.
On September 12, 2002, President Bush addressed the U.N. General Assembly and set out the
history of Iraqi misdeeds over the last two decades and the numerous times that Iraq had not
fulfilled its commitments to comply with various U.N. Security Council resolutions, including
disarmament, since the Gulf War of 1991. He stated that the United States would work with the
U.N. Security Council to deal with Iraq’s challenge. However, he emphasized that if Iraq refused
to fulfill its obligations to comply with U.N. Security Council resolutions, the United States
would see that those resolutions were enforced.45
Subsequently, on September 19, 2002, the White House sent a “draft” joint resolution to House
Speaker Dennis Hastert, House Minority Leader Richard Gephardt, Senate Majority Leader
Thomas Daschle and Senate Minority Leader Trent Lott. This draft would have authorized the
President to use military force not only against Iraq but “to restore international peace and
security in the region.” Subsequently introduced as S.J.Res. 45 on September 26, it served as the
basis for an extensive debate over the desirability, necessity, and scope of a new Congressional
authorization for the use of force. The Senate used this bill as the focus for a debate which began,
after cloture was invoked, on October 3. The Senate debate continued from October 4 until
October 11, 2002, and involved consideration of numerous amendments to the measure. In the
end the Senate adopted H.J.Res. 114 in lieu of S.J.Res. 45.

Declarations of War and Authorizations for the Use of Military Force

The draft measure was not formally introduced in the House. Instead, the vehicle for House
consideration of the issue was H.J.Res. 114. Cosponsored by Speaker Hastert and Minority
Leader Gephardt and introduced on October 2, 2002, H.J.Res. 114 embodied modifications to the
White House draft that were agreeable to the White House, most House and Senate Republicans,
and the House Democratic leadership. The House International Relations Committee reported out
a slightly amended version of the joint resolution on October 7, 2002 (H.Rept. 107-721). The
House adopted the rule governing debate on the joint resolution (H.Res. 474) on October 8, 2002;
and debated the measure until October 10, when it passed H.J.Res. 114 by a vote of 296-133.
Subsequently, the Senate passed the House version of H.J.Res. 114 on October 11 by a vote of 77-
23, and President Bush signed the Authorization for Use of Military Force against Iraq Resolution
of 2002 into law on October 16, 2002.46
In signing H.J.Res. 114 into law, President Bush noted that by passing this legislation the
Congress had demonstrated that “the United States speaks with one voice on the threat to
international peace and security posed by Iraq.” He added that the legislation carried an important
message that “Iraq will either comply with all U.N. resolutions, rid itself of weapons of mass
destruction, and ...its support for terrorists, or will be compelled to do so.” While the President
noted he had sought a “resolution of support” from Congress to use force against Iraq, and
appreciated receiving that support, he also stated that
...my request for it did not, and my signing this resolution does not, constitute any change in
the long-standing positions of the executive branch on either the President’s constitutional
authority to use force to deter, prevent, or respond to aggression or other threats to U.S.
interests or on the constitutionality of the War Powers Resolution.
President Bush went on to state that on the “important question of the threat posed by Iraq,” his
views and goals and those of the Congress were the same. He further observed that he had
extensive consultations with the Congress in the past months, and that he looked forward to
“continuing close consultation in the months ahead.” He stated his intent to submit written reports
to Congress every 60 days on matters “relevant to this resolution.”47
The central element of P.L. 107-243 is the authorization for the President to use the armed forces
of the United States
as he determines to be necessary and appropriate in order to - (1) defend the national security
of the United States against the continuing threat posed by Iraq; and (2) enforce all relevant
United Nations Security Council resolutions regarding Iraq.
As predicates for the use of force, the statute requires the President to communicate to Congress
his determination that the use of diplomatic and other peaceful means will not “adequately protect
the United States ... or ... lead to enforcement of all relevant United Nations Security Council
resolutions” and that the use of force is “consistent” with the battle against terrorism. Like P.L.
102-1 and P.L. 107-40, the statute declares that it is “intended to constitute specific statutory

of Use of U.S. Armed Forces—Side-By-Side Comparison of Public Law 107-243 and Selected Legislative Proposals

Declarations of War and Authorizations for the Use of Military Force

authorization within the meaning of section 5(b) of the War Powers Resolution.” It also requires
the President to make periodic reports to Congress “on matters relevant to this joint resolution.”
Finally, the statute expresses Congress’s “support” for the efforts of the President to obtain
“prompt and decisive action by the Security Council” to enforce Iraq’s compliance with all
relevant Security Council resolutions.
P.L. 107-243 clearly confers broad authority on the President to use force. In contrast to P.L. 102-
1, the authority granted is not limited to the implementation of previously adopted Security
Council resolutions concerning Iraq but includes “all relevant ... resolutions.” Thus, it appears to
have incorporated resolutions concerning Iraq that were subsequently adopted by the Security
Council at least up to the expiration of the UN mandate on December 31, 2008, as well as those
resolutions adopted prior to the enactment of P.L. 107-243. The authority also appears to extend
beyond compelling Iraq’s disarmament to implementing the full range of concerns expressed in
those resolutions. Unlike P.L. 107-40, the President’s exercise of the authority granted is not
dependent upon a finding that Iraq was associated in some direct way with the September 11,
2001, attacks on the U.S. Moreover, the authority conferred can be used for the broad purpose of
defending “the national security of the United States against the continuing threat posed by Iraq.”
Nevertheless, P.L. 107-243 is narrower than P.L. 107-40 in that it limits the authorization for the
use of force to Iraq. It also requires as a predicate for the use of force that the President determine
that peaceful means cannot suffice and that the use of force against Iraq is consistent with the
battle against terrorism.48 P.L. 107-243 further limits the force used to that which the President
determines is “necessary and appropriate.” Finally, as with P.L. 107-40, the statutory
authorization for use of force granted to the President in P.L. 107-243 is not dependent for its
exercise upon prior authorization by the U.N. Security Council.
P.L. 107-243 does not contain explicit time requirements or call for the withdrawal of U.S. troops
by any specific date or set of criteria. Presumably, continued force is authorized so long as Iraq
poses a continuing threat to the United States and the U.S. military presence is not inconsistent
with relevant U.N. resolutions. While it may be argued that the specific threats posed by Iraq
during Saddam Hussein’s regime that were emphasized in the preamble to P.L. 107-243 no longer
exist, it seems reasonable to conclude that the authorization to use force includes authority to use
the military to occupy Iraq, consistent with the international law of armed conflict, until a new
government is able to maintain control over the territory.49 This conclusion is bolstered by U.N.
Security Council resolutions adopted in the aftermath of the invasion. Despite the initial lack of
consensus regarding the legality of the invasion, the Security Council adopted subsequent
resolutions recognizing the occupation of Iraq and generally supporting the coalition’s plans for
bringing about a democratic government in Iraq. Resolution 1511 (Oct. 16, 2003), in paragraph
13:
authorizes a multinational force under unified command to take all necessary measures to
contribute to the maintenance of security and stability in Iraq, including for the purpose of
ensuring necessary conditions for the implementation of the timetable and programme as

well as to contribute to the security of the United Nations Assistance Mission for Iraq, the
Governing Council of Iraq and other institutions of the Iraqi interim administration, and key
humanitarian and economic infrastructure.
Resolution 1546 reaffirmed the authorization for the multinational force (MNF) in Resolution
1511, “noting” that “the presence of the multinational force in Iraq is at the request of the
incoming Interim Government of Iraq.” The terms of the mandate for the MNF are expressed in
paragraph 12, in which the Security Council:
[d]ecides further that the mandate for the multinational force shall be reviewed at the request
of the Government of Iraq or twelve months from the date of this resolution, and that this
mandate shall expire upon the completion of the political process set out in paragraph four
[of Resolution 1546], and declares that it will terminate this mandate earlier if requested by
the Government of Iraq.
The termination of the UN mandate for the MNF is tied directly to the completion of the political
process rather than to any specific date set for that event. In Resolution 1637 (Nov. 11, 2005), the
Security Council reiterated its finding that “the situation in Iraq continues to constitute a threat to
international peace and security,” and extended the MNF mandate until 31 December 2006, to be
reviewed at the request of the Iraqi government or no later than 15 June 2006. The MNF mandate
was ultimately extended until December 31, 2008, at the request of the Iraqi government.50 As of
January 1, 2009, the U.S. presence is authorized by the Withdrawal Agreement,51 an Executive
Agreement negotiated between the United States and Iraq as part of the legal framework meant to
take the place of the UN mandate. It has been argued that the end of the U.N. mandate requires a
new authorization in order for a continued military presence in Iraq;52 however, Congress has
continued to provide finds for military operations in Iraq, and efforts to withdraw the resolution
authorizing force or otherwise bring about an end to the U.S. military presence in Iraq have not
succeeded.53

Declarations of War and Authorizations for the Use of Military Force

Implications Under International Law
Traditionally, peace and war have been deemed under international law to be distinctive forms of
relations between states. Thus, peace has been defined as
a condition in which States maintain order and justice, solve their problems by cooperation,
and eliminate violence. It is a condition in which States respect each other’s sovereignty and
equality, refrain from intervention and the threat or use of force and cooperate with one
another in accordance with the treaties which they have concluded.54
War, in contrast, has been described as “a condition of armed hostility between States,”55 “a
contention, through the use of armed force, between states, undertaken for the purpose of
overpowering another.”56 War has been said to terminate or suspend the laws and customs that
prevail in peacetime and to substitute for them the laws of war. Under the traditional laws of war
enemy combatants can be killed, prisoners of war taken, the enemy’s property seized or
destroyed, enemy aliens interned, and other measures necessary to subdue the enemy and impose
the will of the warring state taken.57 Moreover, the existence of a state of war traditionally has
been deemed to terminate diplomatic and commercial relations and most of the treaty obligations
existing between the warring States.58 A state of war also has brought into play the law of
neutrality with respect to relations between the belligerent and non-belligerent States.
In this traditional understanding a declaration of war has been deemed, in and of itself, to have
the effect of creating a state of war and changing the relationship between the states involved
from one of peace to one of war. That has been the case even if no hostilities actually occur. Some
question exists as to whether international law traditionally deemed a declaration of war to be a
necessary prerequisite to the existence of a state of war;59 but it is clear that under international

1686.
56 von Glahn, Gerhard, Law Among Nations (6th ed.) (1992), at 669.
57 In his treatise Law of Nations (1858), at 346, Emmerich de Vattel stated the general principles governing the conduct
of war as follows:
As soon, therefore, as we have declared war, we have a right to do against the enemy whatever we
find necessary for the attainment of that end—for the purpose of bringing him to reason, and
obtaining justice and security from him.
The lawfulness of the end does not give us a real right to anything further than barely the means
necessary for the attainment of that end. Whatever we do beyond that, is reprobated by the law of
nature, is faulty, and condemnable at the tribunal of conscience. Hence it is that the right to such or
such acts of hostility varies according to circumstances. What is just and perfectly innocent in war,
in one particular situation, is not always so on other occasions. Right goes hand in hand with
necessity and the exigency of the case, but never exceeds them.
58 Cushman K. Davis, A Treatise on International Law (1901), at 141 stated:
War abrogates all treaties between the belligerents; its suspends all commercial intercourse and
relations between their respective subjects, and makes them unlawful; it dissolves all partnerships
between subjects of the belligerents; it suspends the operation of all executory contracts during the
war .... It open a great gulf of non-intercourse between the two nations, and imposes disability upon
the subjects of each to do any kind of civil business with those of the other ....
59 Commentators differ on this issue. Grotius claimed that a declaration was a necessary precondition to the existence
of a war. See Ingrid Detter, The Law of War (2000), at 10. Vattel said a declaration communicated to the enemy was
demanded by “humanity” prior to the inception of a war, served as an inducement to the enemy to “terminate the

Declarations of War and Authorizations for the Use of Military Force

law a declaration of war has been viewed as “creating the legal status of war ... [and giving]
evidence that peace has been transmuted into war, and that the law of war has replaced the law of
peace.”60
Authorizations for the use of force, in contrast, have not been seen as automatically creating a
state of war under international law. The U.S. Court of Claims, in construing the statutes
authorizing the limited use of force against France in 1798, described how their effects differed
from those that followed in the wake of a war:
[Our naval vessels] might seize armed vessels only, and only those armed vessels which had
already committed depredations, or those which were on our coast for the purpose of
committing depredations, and they might retake an American vessel captured by such an
armed vessel. This statute is a fair illustration of the class of laws enacted at this time; they
directed suspension of commercial relations until the end of the next session of Congress, not
indefinitely ...; they gave power to the President to apprehend the subjects of hostile nations
whenever he should make “public proclamation” of war ..., and no such proclamation was
made; they gave him authority to instruct our armed vessels to seize French “armed,” not
merchant, vessels ..., together with contingent authority to augment the army in case war
should break out or in case of imminent danger of invasion ....
If war existed, why authorize our armed vessels to seize French armed vessels? War itself
gave that right, as well as the right to seize merchantmen which the statutes did not permit. If
war existed why empower the President to apprehend foreign enemies? War itself placed that
duty upon him as a necessary and inherent incident of military command. Why, if there was
war, should a suspension of commercial intercourse be authorized, for what more complete
suspension of that intercourse could there be than the very fact of war?
There was no declaration of war; the tribunals of each country were open to the other—an
impossibility were war in progress; diplomatic and commercial intercourse were admittedly
suspended; but during many years there was no intercourse between England and Mexico,
which were not at war; there was retaliation and reprisal, but such retaliations and reprisals

difference without the effusion of blood,” and was “the constant practice among the powers of Europe.” Vattel, supra
footnote 57, at 315. But he also stated that “there seems to be no absolute necessity for a formal declaration of war to
render it legal.” Id. at 316. Kent’s Commentary on International Law (1878), at169-171, stated:...
[I]t has become settled by the practice of Europe that war may lawfully exist by a declaration which
is unilateral only, or without a declaration on either side. It may begin with mutual hostilities. Since
the Peace of Versailles in 1763, formal declarations of war of any kind seem to have been
discontinued, and all the necessary and legitimate consequences of war flow at once from a state of
public hostilities, duly recognized, and explicitly announced, by a domestic manifesto or State
paper.”
A legal requirement of a formal declaration of war was included in the Hague Convention (III) Relative to the Opening
of Hostilities, negotiated in 1907 and ratified by 42 countries (including the U.S.), which stated as follows:
The Contracting Powers recognize that hostilities between themselves must not commence without
previous and explicit warning, in the form either of a reasoned declaration of war or of an
ultimatum with conditional declaration of war.
Although this treaty remains in effect for its Parties, its requirement regarding a declaration of war has generally fallen
into desuetude; and a declaration generally is no longer regarded as a legal prerequisite to the use of force. Von Glahn,
supra footnote 56, at 600, states: “ ... [G]eneral opinion has sanctioned a commencement of hostilities without issuing a
declaration of war or other formal notice of intent to resort to the use of force.”

Declarations of War and Authorizations for the Use of Military Force

have often occurred between nations at peace; there was a near approach to war, but at no
time was one of the nations turned into an enemy of the other in such manner that every
citizen of the one became the enemy of every citizen of the other; finally, there was not that
kind of war which abrogated treaties and wiped out, at least temporarily, all pending rights
and contracts, individual and national.61
Whether this traditional understanding of war and of the effect of a declaration of war continues
to be viable is a matter of considerable dispute among scholars. The right of a state to initiate war,
many contend, has been outlawed by such international agreements as the Kellogg-Briand Peace
Pact and the Charter of the United Nations. In the Kellogg-Briand Peace Pact,62 for instance, the
Parties stated that they “condemn recourse to war for the solution of international controversies,
and renounce it as an instrument of national policy in their relations with one another.”63 After
World War II the Nuremberg Tribunal gave teeth to this commitment by ruling that the Pact
rendered aggressive war illegal under international law and makes those who plan and wage such
a war guilty of a crime.64 The Charter of the United Nations, in turn, states one of its purposes to
be “to save succeeding generations from the scourge of war,” and it requires its Members “to
refrain from the threat or use of force against the territorial integrity or political independence of
any State, or in any other manner inconsistent with the Purposes of the United Nations.”65
Moreover, it provides for a system of collective security through the Security Council as the
primary means of maintaining or restoring international peace and security.66 Both instruments, it
is contended, recognize that the concept of war as a legal right of states, except in self-defense,67
has been superseded. (The United States, of course, is a Party not only to the Charter but also to
the Pact, and it still regards the latter as continuing to be in force.68) Whether the traditional
concept of war remains valid has been further complicated by the increasing participation in
armed conflict of non-State actors such as insurgents, freedom fighters, and terrorists.
The clarity of the consequences of a state of war in traditional international law has also become
muddied in the modern era. Most States since 1945, even when engaged in armed conflict, have
resisted describing the conflict as a war.69 States so engaged have not always automatically

terminated diplomatic and commercial relationships,70 and the discontinuance of treaty
obligations has increasingly been deemed to require a treaty-by-treaty examination.71 Moreover,
conventions that attempt to regulate the means used to wage war, such as the Hague Conventions
and other more recent agreements,72 and those that attempt to ameliorate the consequences of war
for certain categories of persons, such as the Geneva Conventions,73 are deemed to apply to
armed conflicts regardless of what label the Parties attach to them. A state of war still gives rise to
“a mutual right to kill in battle,”74 triggers application of the various conventions regulating the
means of waging war as well as of the general principles of necessity and proportionality, and
brings into play the Geneva Conventions. But its other legal consequences seemingly have
become less determinate.
Perhaps as a consequence of these developments, declarations of war have fallen into disuse and
are virtually never issued in modern conflicts. One commentator asserts that since 1945 “[t]here
are no cases of a formal declaration of war having been delivered by one state to another through
diplomatic channels....”75 As noted above, the United States last declared war in 1942 against
Rumania and has since adopted only authorizations for the use of force.
Thus, declarations of war may have become anachronistic in contemporary international law. The
legal right of States to engage in war has seemingly become constrained (for other than defensive
purposes), and the most salient international laws regarding the means of waging war and the

70 The modern codification of the law of diplomatic relations—the Vienna Convention on Diplomatic Relations, 23
UST 3227 (1972)—does not specifically address the effect of a declaration of war or of an authorization for the use of
force but does address what is required in cases of “armed conflict.” Whenever diplomatic relations are broken, the
Convention requires that diplomatic privileges and immunities not cease until the diplomat leaves the country and that
the receiving state assist diplomats and their families in leaving “at the earliest possible moment, ... even in case of
armed conflict” (Articles 38 and 44). The Convention also requires that a state respect and protect the premises of a
diplomatic mission and its property and archives during any time in which diplomatic relations have been broken,
including “in the case of armed conflict” (Article 45(a)).

Declarations of War and Authorizations for the Use of Military Force

protection of certain categories of persons apply to the circumstance of armed conflict regardless
of whether war has been declared. That circumstance can arise in the wake of an authorization to
use force as well. States likely still retain a right to issue declarations of war, at least in exercising
the right of self-defense; and such a declaration seemingly would still automatically create a state
of war. But it is not clear that the legal consequences under international law that would flow
from a declaration differ dramatically from those that occur if an armed conflict comes into being
pursuant to an authorization for the use of force.
Implications Under Domestic Law
Early American jurisprudence drew a distinction between general, or perfect, war and limited, or
imperfect, war, and understood a declaration of war under Article I, § 8, of the Constitution to
commit the nation to a general war. Justice Washington, in Bas v. Tinghy,76 described the
distinction as follows:
It may, I believe, be safely laid down, that every contention by force between two nations, in
external matters, under the authority of their respective governments, is not only war, but
public war. If it be declared in form, it is called solemn, and is of the perfect kind; because
one whole nation is at war with another whole nation; and all the members of the nation
declaring war are authorised to commit hostilities against all the members of the other, in
every place, and under every circumstance. In such a war all the members act under a general
authority, and all the rights and consequences of war attach to their condition.
...[H]ostilities may subsist between two nations more confined in its nature and extent; being
limited as to places, persons, and things; and this is more properly termed imperfect war;
because not solemn, and because those who are authorised to commit hostilities, act under
special authority, and can go no farther than to the extent of their commission. Still,
however, it is public war, because it is an external contention, by force, between some of the
members of the two nations, authorised by the legitimate powers.77
Justice Chase, more simply, stated: “Congress is empowered to declare a general war, or congress
may wage a limited war; limited in place, in objects, and in time.”78
Thus, at least in the 18th and 19th centuries, authorizations for the use of force were understood to
be included within Congress’s power to declare war and to have narrower legal consequences
than declarations of war. Declarations were reserved for general war against particular countries
and empowered the President “to use the whole land and naval force of the United States”
(United Kingdom in 1812), “to employ the militia, naval, and military forces of the United
States” (Mexico in 1846), or “to use the entire land and naval forces of the United States” (Spain
in 1898) to prosecute the war. Authorizations, in contrast, allowed the President to use the
American navy against the vessels of France, the Bey of Tripoli, and the Dey of Algiers, or
against piracy generally.
In the modern era authorizations have sometimes been quite broad79; and some have, arguably,
been equivalent in scope to a declaration of war. But the domestic legal consequences that flow

Declarations of War and Authorizations for the Use of Military Force

from such authorizations still are substantially more limited than those that would flow from a
declaration of war.
Both declarations of war and authorizations for the use of force have the effect of eliminating the
time limits otherwise imposed on the President’s use of the armed forces under the War Powers
Resolution; and both may legitimate the killing of foreign officials that might otherwise be
prohibited by the executive order on assassinations. The capture of enemy combatants on the
battlefield and their detention until hostilities have subsided is implied in an authorization to use
ground forces,80 just as it would be included in a formal declaration of war.
But a declaration of war automatically brings into effect a number of statutes that confer special
powers on the President and the Executive Branch, especially concerning measures that have
domestic effect. A declaration, for instance, activates statutes that empower the President to
interdict all trade with the enemy, order manufacturing plants to produce armaments and seize
them if they refuse, control transportation systems in order to give the military priority use, and
command communications systems to give priority to the military. A declaration triggers the
Alien Enemy Act, which gives the President substantial discretionary authority over nationals of
an enemy state who are in the United States. It activates special authorities to use electronic
surveillance for purposes of gathering foreign intelligence information without a court order
under the Foreign Intelligence Surveillance Act. It automatically extends enlistments in the armed
forces until the end of the war, can make the Coast Guard part of the Navy, gives the President
substantial discretion over the appointment and reappointment of commanders, and allows the
military priority use of the natural resources on the public lands and the continental shelf.
An authorization for the use of force does not automatically trigger any of these standby statutory
authorities. Some of them can come into effect if a state of war in fact comes into being after an
authorization for the use of force is enacted; and the great majority of them, including many of
the most sweeping ones, can be activated if the President chooses to issue a proclamation of a
national emergency. But an authorization for the use of force, in itself and in contrast to a
declaration of war, does not trigger any of these standby authorities.
On the other hand, the authorization to use force in response to the terrorist attacks of 2001 has
been asserted as legal authority for executive actions in the domestic context, the validity of
which remains unresolved. The executive branch asserted that the authorization permits detention
without trial of persons arrested in the United States on suspicion of Al Qaeda related terrorism,
which it regarded as bolstered by the Supreme Court’s Hamdi decision finding the detention of
enemy combatants captured in Afghanistan to be authorized as “a fundamental incident of waging
war.”81 While there is limited authority to support military trials of enemy soldiers captured

occurred on September 11, 2001 ....”) and P.L. 107-243 (Oct. 16, 2002) (authorizing the President to the use the armed
forces “as he determines to be necessary and appropriate in order to—(1) defend the national security of the United
States against the continuing threat posed by Iraq; and (2) enforce all relevant United Nations Security Council
resolutions regarding Iraq.”
80 See Hamdi v. Rumsfeld, 542 U.S. 507, 518 (2004) (O’Connor, J., plurality opinion); id. at588-589 (Thomas, J.,
dissenting). The plurality interpreted the AUMF as authorizing the detention of a U.S. citizen captured in Afghanistan
as a “fundamental incident of waging war,” and was thus a statute authorizing detention within the meaning of the Non-
Detention Act, 18 U.S.C.A. § 4001(a), which prohibits the detention of any citizen absent an act of Congress.

Declarations of War and Authorizations for the Use of Military Force

within the United States, in previous wars the Alien Enemy Act would likely have been the chief
means of interning suspected enemies domestically.82 Under the executive branch view, the
authorization to use force could be construed as broader than a declaration of war in that it is seen
to authorize detention powers without any of the few rules or restrictions specified in the Alien
Enemy Act, and to authorize the detention of U.S. citizens as an exception to the Non-Detention
Act.83 Similarly, the executive branch argued that the authorization to use force must also be read
to permit the conduct of certain types of electronic surveillance outside of the strictures of the
Foreign Intelligence Surveillance Act, even though that act provides for only a two-week
exception triggered by a declaration of war.84 Accordingly, it is possible that any similarly broad
authorization to use force may be read to authorize any power that may properly be regarded as
“a fundamental incident of waging war” under the circumstances, at least as implied exceptions to
statutes that admit of statutory exception.
The following subsections give an overview of some of the more salient domestic legal
consequences of a declaration of war or authorization for the use of force. They are followed by a
section setting forth a detailed list of the standby statutory authorities that can be triggered by a
declaration of war, a state or war, and/or a proclamation of national emergency.
The War Powers Resolution
Both a declaration of war and an authorization for the use of force have significant implications
with respect to the War Powers Resolution (WPR).85 The WPR was enacted over President
Nixon’s veto in 1973 purportedly to restore a Congressional role in authorizing the use of force
that was thought by many to have been lost in the Cold War and the Vietnam War. To that end the
WPR mandates that the President consult with the Congress “in every possible instance” prior to
introducing U.S. armed forces into hostilities and regularly afterwards. Section 4(a) of the WPR
further requires the President, “in the absence of a declaration of war,” to report to Congress
within 48 hours in any case in which United States Armed Forces are introduced—

83 18 U.S.C. § 4001(a) provides that “No citizen shall be imprisoned or otherwise detained by the United States except
pursuant to an Act of Congress.” The 4th Circuit Court of Appeals validated the detention of a U.S. citizen on the basis
of his presence during hostilities in Afghanistan, but the government transferred the petitioner to federal court for trial
on terrorism charges before the Supreme Court could take the case on appeal. Padilla v. Hanft, 423 F.3d 386 (4th Cir.),
motion to vacate denied 432 F.3d 582 (4th Cir. 2005), cert. denied 547 U.S. 1062 (2006). A plurality of the 4th circuit
sitting en banc upheld the detention of a non-citizen suspected of being a “sleeper agent” for Al Qaeda, although the
court did not agree on a definition of “enemy combatant,” or individual subject to detention. The Supreme Court
vacated the decision at the request of the government after the petitioner was transferred to federal court for trial on
terrorism charges. Al-Marri v. Pucciarelli, 534 F.3d 213 (4th Cir. 2008)(per curiam), vacated and remanded sub nom.

84 The Bush Administration argued that intelligence collection is authorized as an incident to the use of force, and that
restrictions under FISA therefore did not apply to electronic surveillance conducted for anti-terrorism purposes because
section 109 of FISA provides an exception to the criminal prohibition against electronic surveillance unless “authorized
by statute.” (50 U.S.C.A. § 1809, prior to 2008 amendment to clarify meaning of “authorized by statute”). Congress
passed the Protect America Act , P.L. 110-55, to provide additional authority for electronic surveillance.

Declarations of War and Authorizations for the Use of Military Force

(1) into hostilities or into situations where imminent involvement in hostilities is clearly
indicated by the circumstances;
(2) into the territory, airspace or waters of a foreign nation, while equipped for combat,
except for deployments which relate solely to supply, replacement, repair, or training of such
forces; or
(3) in numbers which substantially enlarge United States Armed Forces equipped for combat
already located in a foreign nation.
Section 5(b) of the Resolution, in turn, requires that if a report has been submitted or was required
to be submitted under § 4(a)(1) above, the President shall terminate the involvement of U.S.
forces unless Congress
(1) has declared war or has enacted a specific authorization for such use of United States
Armed Forces;
(2) has extended by law such sixty-day period, or
(3) is physically unable to meet as a result of an armed attack upon the United States.86
Thus, congressional enactment of either a declaration of war or an authorization for the use of
force pursuant to § 5(b) has the effect of tolling the 60-90 day withdrawal mandate of the WPR.
Each of the last three authorizations for the use of force enacted—the 1991 Gulf War
authorization, the September 18, 2001, authorization with respect to terrorist attacks, and the
October 16, 2002, authorization with respect to Iraq—have explicitly stated that they constitute
the authorization required by § 5(b) of the WPR. Each, in other words, has tolled the 60-90 day
limitation that the WPR otherwise would impose on the use of military force by the President. All
three authorizations have further specified that “[n]othing in this resolution supercedes any
requirement of the War Powers Resolution.” That appears to mean that the consultation and
reporting requirements of the WPR still apply.
Trading with the Enemy Act and the International Emergency
Economic Powers Act

Two related statutes, the Trading With the Enemy Act87 (TWEA) and the International Emergency
Economic Powers Act88 (IEEPA), grant the President extraordinary powers to control foreign-
owned property and foreign trade transactions with designated countries under certain exceptional
circumstances. TWEA comes into effect upon a declaration of war or the existence of a state of
war, while IEEPA is triggered solely by a presidential declaration of national emergency. Neither
statute is triggered by an authorization for the use of force (unless, in the case of TWEA, the
authorization eventually leads to the existence of a state of war). IEEPA is the authority most
commonly invoked to freeze or block the assets of foreign states, companies, or individuals
located within the jurisdiction of the United States.

Declarations of War and Authorizations for the Use of Military Force

Until 1977 the broad range of economic authorities granted by TWEA could be exercised both in
times of war and in times of national emergency. However, in 1977 Congress limited the
prospective application of TWEA to times of declared or undeclared war only and enacted IEEPA
to apply during times of a national emergency declared by the President. Under TWEA the
President may
(A) investigate, regulate, or prohibit, any transactions in foreign exchange, transfers of credit
or payments or payments between, by, through, or to any banking institution, and the
importing, exporting, hoarding, melting, or earmarking of gold or silver coin or bullion,
currency or securities, and
(B) investigate, regulate, direct and compel, nullify, void, prevent or prohibit, any
acquisition, holding, withholding, use, transfer, withdrawal, transportation, importation or
exportation of, or dealing in, or exercising any right, power, privilege with respect to, or
transactions involving, any property in which any foreign country or a national thereof has
any interest, by any person, or with respect to any property, subject to the jurisdiction of the
United States; and any property or interest of any foreign country or national thereof shall
vest, when, as, and upon the terms, directed by the President, in such agency or person as
may be designated from time to time by the President, and upon such terms and conditions as
the President may prescribe such interest or property shall be held, used, administered,
liquidated, sold, or otherwise dealt with in the interest of and for the benefit of the United
States ....89
IEEPA replicates many of TWEA’s powers to regulate international transactions,90 but it does not
include TWEA authorities relative to purely domestic transactions, the regulation of bullion, and
seizure of records.91 It also does not contain TWEA’s general authority to take title to foreign
assets. But Congress did amend IEEPA in the “USA PATRIOT Act” in 2001 to authorize the
President to confiscate and take title to
any property, subject to the jurisdiction of the United States, of any foreign person, foreign
organization, or foreign country that he determines has planned, authorized, aided or engaged
in ... hostilities or attacks against the United States ....92
Congress further amended both IEEPA and TWEA in the “Terrorism Risk Insurance Act of 2002”
to provide that the assets of foreign terrorist states that have been frozen in the U.S. pursuant to
either statute may be used to satisfy certain civil judgments against them.93
As noted, IEEPA is triggered solely by a declaration of national emergency, while TWEA applies
in time of war. Thus, TWEA is not dependent upon a declaration of war, but it can be triggered by
such a declaration. Neither appears to be triggered by an authorization for the use of force, unless
and until, in the case of TWEA, a state of war actually develops.

Declarations of War and Authorizations for the Use of Military Force

Other Economic Authorities
As noted, a declaration of war gives the President full authority over trade relations with the
enemy. Other statutes triggered by a declaration give the President the authority to order plants to
convert to the production of armaments and to seize those that refuse to do so,94 to take control of
the Tennessee Valley Authority in order to manufacture explosives or for other military
purposes,95 to assume control of transportation systems for military purposes,96 to condemn land
for military uses,97 to have the right of first refusal over natural resources,98 and to take control of
communications facilities.99 It also gives the President full power over agricultural exports.100 An
authorization for the use of force, in itself, does not trigger any of these authorities.
Alien Enemy Act
First enacted in 1798, the Alien Enemy Act101 broadly authorizes the President to deport, detain,
or otherwise condition the stay of alien enemies in the U.S. in cases of “declared war” or “any
invasion or predatory incursion ... perpetrated, attempted, or threatened against the territory of the
United States by any foreign nation or government ....” The act implements the internationally
recognized right of every nation to protect itself during times of war from individuals whose
primary allegiance lies with a hostile foreign power. Given this premise, the Supreme Court has
observed that “[e]xecutive power over enemy aliens, undelayed and unhampered by litigation, has
been deemed, throughout our history, essential to war-time security.”102
The President must publicly proclaim the event that gives rise to activation of the act and make
regulations regarding the treatment of those aliens. But once he does so, his power to “apprehend,
restrain, secure, and remove” enemy aliens extends to all “natives, citizens, denizens, or subjects
of the hostile nation or government, being of the age of fourteen years and upward, who shall be
in the United States and not actually naturalized.”103 The President may intern or remove enemy
aliens or set lesser restraints on them, and may adopt any “regulations which are found necessary
in the premises and for the public safety.”104 Thus, President Woodrow Wilson, for example,
barred alien enemies during World War I from possessing firearms and explosives, coming within
a half a mile of a military facility or munitions factory, residing in certain areas, possessing
certain communications equipment, and publishing certain types of materials. President Franklin
D. Roosevelt authorized similar restrictions during World War II and, additionally, set up over
100 community hearing boards to make internment recommendations to the Attorney General.105

Declarations of War and Authorizations for the Use of Military Force

The procedural rights of aliens who are subject to the Alien Enemy Act are drastically restricted
compared with those that aliens otherwise enjoy, including hearing rights under the removal
provisions of the Immigration and Nationality Act.106 The scope of judicial review is equally
circumscribed.107 Among the few rights recognized under the act, alien enemies subjected to
removal may, if not chargeable with “actual hostility” or other crime against public safety, be
entitled to the time allowed by applicable treaty or order to wind up his or her affairs here.108 A
very limited right to judicial review under a petition for a writ of habeas corpus also is
recognized. Generally, however, the power of the President to control alien enemies under the act
is extraordinary.
As noted, the act does not appear to be triggered solely by an authorization for the use of force.
Criminal Law
There are a number of civilian federal criminal law provisions that apply explicitly to specified
conduct in time of war. They do not appear to distinguish between circumstances involving a
declaration of war and other situations in which a state of war may exist absent a declaration of
war, although courts (and Congress) have in some cases construed “time of war” or “at war” to
require a formal declaration by Congress. Thus, these statutes may be triggered by a declaration
of war, but they also may apply in circumstances where a state of war is deemed to exist.
Consequently, these criminal prohibitions do not appear to be triggered by an authorization for
the use of force, unless and until a state of war develops. These statutes include, for example:109
(a) 18 U.S.C.A. § 443 (willful secreting, mutilating, obliterating or destroying records of a
war contractor, that is, a holder of a prime or subcontract connected with or related to the
prosecution of a war);
(b) 18 U.S.C.A. § 757 (procuring the escape of a prisoner of war held by the United States or
any of its allies or the escape of an apprehended or interned enemy alien held by the United
States or its allies; aiding or assisting such escape or assisting the prisoner of war or enemy
alien after his escape; or attempting or conspiring to do any of the above);
(c) 18 U.S.C.A. § 792 (harboring or concealing persons known or believed to have
committed or to be about to commit an offense under 18 U.S.C. §§ 793 or 794);
(d) 18 U.S.C.A. § 793 (gathering, transmitting or losing information related to the national
defense with the intent or reason to believe that it is to be used to the injury of the United
States or to the benefit of a foreign nation. Includes, among other things, such actions with
respect to information on any place in which any vessel, aircraft, arms, munitions, or other
materials or instruments for use in time of war are being prepared, repaired, stored, or are the
subject of research or development; or with respect to any prohibited place so designated by

with the intent or reason to believe that it is to be used to the injury of the United States or to
the advantage of a foreign nation. Subsection (b) deals with recording, publishing, or
communicating or attempting to elicit information regarding movements, numbers, condition
or disposition of Armed Forces, ships, aircraft or war materials, with the intent that the
information be communicated to the enemy in time of war. It also covers communicating to
the enemy in time of war information on plans or conduct of naval or military operations or
defense measures.)110
(f) 18 U.S.C.A. § 1091 (genocide in time of peace or in time of war);
(g) 18 U.S.C.A. § 1653 (aliens who are found and taken on the sea making war against the
United States or engaging in piracy against U.S. vessels or property);
(h) 18 U.S.C.A. § 2153 (when the United States is at war or when a national emergency has
been declared, willful destruction of war material, war premises, or war utilities, with intent
or reason to believe that such actions may injure, interfere with, or obstruct the United States
or associate nations in their war or defense activities; and conspiracy to do so);
(i) 18 U.S.C.A. § 2154 (in times of war or national emergency, willfully producing defective
war material, war premises, or war utilities with intent to injure, interfere with, or obstruct
the war or defense activities of the United States or associate nations);
(j) 18 U.S.C.A. § 2381 and U.S. Constitution, Art. 3, Sec. 3, Cl. 1 (while owing allegiance to
the United States, levying war against the United States or adhering to its enemies, giving
them aid and comfort. Constitution requires confession in open court or testimony of two
witnesses to the same overt act to convict for treason);
(k) 18 U.S.C.A. § 2382 (misprision of treason);
(l) 18 U.S.C.A. § 2384 (seditious conspiracy to overthrow or destroy by force the
Government of the United States or to levy war against the United States);
(m) 18 U.S.C.A. § 2388 (willfully engaging in certain activities in time of war with intent to
adversely affect armed forces of the United States or to obstruct enlistment or recruitment;
conspiracy to do so; harboring a person knowing or having reason to believe that the person
has engaged in such conduct);
(n) 18 U.S.C.A. § 2389 (recruiting soldiers or sailors within U.S. jurisdiction to engage in
armed hostilities against the United States); and
(o) 18 U.S.C.A. § 2441 (war crimes).

110 It should be noted that other espionage provisions in 18 U.S.C.A. §§ 793-799 do not explicitly require a state or time
of war to apply, but would presumably apply in wartime as well as peacetime. Unlawful communication of, receipt of,
tampering with, or disclosure of restricted data with respect to special nuclear material is addressed in 42 U.S.C.A. §§
2274-77. Here again, wartime is not distinguished from other times in the application of these provisions.
Congressional Research Service

Declarations of War and Authorizations for the Use of Military Force

It should also be noted that other federal and state criminal law provisions,111 which do not draw
distinctions between conduct in time of war and at other times, also apply during wartime.112 For
example, 18 U.S.C.A. § 175 prohibits knowing development, stockpiling, acquisition, possession
or retention of any biological agent, toxin, or delivery system for use as a weapon, or knowing
assistance to a foreign state to do so. 18 U.S.C.A. § 229, with certain exceptions, prohibits similar
conduct with respect to chemical weapons. 18 U.S.C.A. § 831 prohibits specific transactions or
actions involving nuclear materials, while 42 U.S.C.A. § 2284 deals with sabotage of nuclear
facilities or fuel. 18 U.S.C.A. § 2332a prohibits certain uses of weapons of mass destruction.
Other explosives offenses are covered in 18 U.S.C.A. § 844. Hostage-taking is addressed in 18
U.S.C.A. § 1203, while kidnapping is covered by 18 U.S.C.A. § 1201. 18 U.S.C.A. § 1116 deals
with murder or manslaughter of foreign officials, official guests, or internationally protected
persons. 18 U.S.C.A. § 1114 addresses the murder or attempted murder of federal officers and
employees, including members of the uniformed services, while they are engaged in or on
account of the performance of official duties. It also covers murder or attempted murder of any
person assisting an officer or employee of the United States in the performance of those duties or
on account of that assistance.113
Statutes of limitations, which preclude prosecutions after a specific amount of time has lapsed
(typically five years), may also be affected during wartime. When the United States “is at war” or
Congress has authorized the use of military force within the meaning of the War Powers
Resolution, the Wartime Suspension of Limitations Act (“Suspension Act”), codified at 18 U.S.C.
§ 3287, extends the statute of limitations for the prosecution of certain crimes against the United
States for five years beyond the termination of hostilities. Originally enacted during World War II,
the Suspension Act previously extended the statute of limitations in relevant cases until three
years after the end of hostilities only “when the United States is at war.” One court had construed
this language to refer only to a war declared by Congress, and held that the 1990-91 Persian Gulf
conflict, although authorized by Congress, did not qualify.114 Apparently also construing the

111 The provisions noted in this paragraph are intended as examples, rather than as an exhaustive list.
112 There are also a number of provisions in 18 U.S.C.A. §§ 958-67 that may be triggered by conduct during wars
involving other nations with whom the United States is at peace or during wars in which the United States is neutral.
These deal, for example, with: enlisting in the service of a foreign government to serve in war against a nation with
whom the United States is at peace; taking part in or facilitating a military or naval expedition against a friendly nation;
strengthening the armed vessel of a foreign nation which is at war with a nation with whom the United States is at
peace; arming a vessel to be used against a friendly nation; authorizing the taking out or attempting to take out of a U.S.
port a detained vessel of a belligerent nation; delivering an armed vessel to a belligerent nation in a conflict in which
the United States is neutral; or authorizing the taking out or attempting to take out of a U.S. port a vessel the departure
of which has been prohibited in aid of neutrality.
113 Some of these statutes are among a number of federal statutes which implicitly or explicitly have extraterritorial
application. This raises a question as to whether or to what extent the existence of a state of open hostilities or a
declaration of war would affect the availability of extraterritorial application of such provisions. An exploration of this
issue is beyond the scope of this report. For a general discussion of extraterritorial application of federal criminal law,
including appendices addressing federal criminal laws which enjoy express extraterritorial application and federal
crimes subject to federal prosecution when committed overseas, see, CRS Report 94-166, Extraterritorial Application
of American Criminal Law

1) the extent of the authorization given by Congress by the President to act; 2) whether the conflict
is deemed a “war” under accepted definitions of the term and the rules of international law; 3) the
size and scope of the conflict (including the cost of the related procurement effort); and 4) the

phrase “is at war” to mean pursuant to a declaration of war,115 Congress amended the provision in
2008116 to trigger its application also upon the enactment of an authorization to use military force
“as described in section 5(b) of the War Powers Resolution (50 U.S.C. 1544 (b)).”117 (The
military counterpart to the provision, found in 10 U.S.C. § 843(f), was not amended. It continues
to suspend the applicable statute of limitations for three years beyond the end of hostilities, and
applies “when the United States is at war.”)
There are other criminal law provisions applicable to the military in the Uniform Code of Military

Accompany S. 2892, 110th Cong., 2nd sess., July 25, 2008, S.Rept. 110-431. The Report explains that:
Technically, Section 3287 only applies to declared wars, not circumstances where Congress has
authorized the use of military force, as in the recent wars in Iraq and Afghanistan. The amendment
to Section 3287 specifically tracks the text of the Congressional authorizations for the use of the
Armed Forces in Iraq and Afghanistan and refers only to those authorizations described in the War
Powers Resolution (50 U.S.C. 1544(b)). As a result, only significant military actions requiring
Congressional action would trigger this suspension of the statute of limitations. This amendment is
not intended to apply to peacekeeping missions under the auspices of the United Nations or military
actions not specifically authorized by Congress pursuant to the War Powers resolution. This
language is intended to apply the suspension of statute of limitations to the wars in Iraq and
Afghanistan.
Id. at 5.
The language of S. 2892 (110th Cong.) was later incorporated into the Consolidated Security, Disaster Assistance, and
Continuing Appropriations Act, 2009, H.R. 2638, and Duncan Hunter National Defense Authorization Act for Fiscal
Year 2009, S. 3001. Both were enacted, but the later-enacted version was subsequently repealed retroactively, P.L.

116 P.L. 110-329, title VIII, § 8117. The amended provision also requires notice to Congress if hostilities are ended
pursuant to presidential proclamation.
117 In a case subsequent to the enactment of the amendment but involving offenses that occurred earlier, the court
dismissed some counts of a complaint as time-barred based on the absence of a formal declaration of war. United States
v. Western Titanium, Inc.
, 2010 WL 2650224 (S.D. Cal. 2010). The court explained that its initial inclination was to
adopt the Prosperi approach to determine whether the United States was at war when the offenses were committed, it
ultimately concluded that the “extensive post-hoc factual determinations required by Prosperi render its application too
ambiguous and uncertain in the context of a criminal statute of limitation.” Id. at *3. The court further remarked that:
Whatever Congress intended by the phrase “at war” in the WSLA, it cannot have meant a definition
not capable of determination until a court conducts a subjective analysis years after the commission
of an offense.

Declarations of War and Authorizations for the Use of Military Force

Foreign Intelligence Surveillance
The Foreign Intelligence Surveillance Act (FISA), as amended, in pertinent part, authorizes
electronic surveillance, physical searches, and the use of pen registers and trap and trace devices
to gather foreign intelligence information and sets out the procedures and circumstances under
which each of these investigative tools may be used.119 In the event of a declaration of war, FISA
authorizes the use of each of these investigative tools to gather foreign intelligence for up to 15
days without a court order. For electronic surveillance subsequent to a declaration of war, FISA
provides, at 50 U.S.C.A. § 1811, that:
Notwithstanding any other law, the President, through the Attorney General, may authorize
electronic surveillance without a court order under this subchapter to acquire foreign
intelligence information for a period not to exceed fifteen calendar days following a
declaration of war by the Congress.
In the context of physical searches, 50 U.S.C.A. § 1829 includes language similar to that in
§ 1811:
Notwithstanding any other provision of law, the President, through the Attorney General,
may authorize physical searches without a court order under this subchapter to acquire
foreign intelligence information for a period not to exceed 15 calendar days following a
declaration of war by the Congress.
For pen registers and trap and trace devices, 50 U.S.C.A. § 1844 provides that
Notwithstanding any other provision of law, the President, through the Attorney General,
may authorize the use of a pen register or trap and trace device without a court order under
this subchapter to acquire foreign intelligence information for a period not to exceed 15
calendar days following a declaration of war by Congress.
None of these provisions appears to be triggered by an authorization for the use of force or the
existence of a state of war under any authority other than a congressional declaration of war.120
In addition to the foregoing provisions, FISA has been amended to authorize the use of these
investigative tools without a court order for foreign intelligence purposes in “emergency”
circumstances as determined by the Attorney General. To do so the Attorney General must (1)
find that an emergency exists, (2) determine that the factual basis for the issuance of an order to
approve such surveillance, physical search, or pen register or trap and trace device also exists, (3)
advise a judge of the U.S. Foreign Intelligence Surveillance Court (FISC) that a decision to use
the emergency authority has been made, and (4) apply to the FISC judge so notified for a court
order as soon as practicable (but no later than within 72 hours in the case of an electronic
surveillance or physical search or 48 hours in the case of a pen register or trap and trace

119 Electronic surveillance under FISA is addressed at 50 U.S.C.A. §§ 1801 et seq.; foreign intelligence physical
searches are addressed at 50 U.S.C. §§ 1821 et seq.; and pen registers and trap and trace devices under FISA are dealt
with at 50 U.S.C. §§ 1841 et seq.
120 The Bush Administration took the position that the authorization to use force in response to the 9/11 attacks, P.L.
107-40, implicitly authorized wiretaps without judicial order without time limits as a fundamental incident of waging
war, notwithstanding the existence of these provisions. See DOJ White Paper, supra footnote 43; CRS Report R40888,

device).121 These provisions do not expressly address the question of whether such emergency
procedures might be triggered either by an authorization for the use of force or by a
Congressional declaration of war. However, depending upon the circumstances involved, these
emergency powers, or other provisions within FISA,122 might be utilized.
Assassination
As noted in the foregoing discussion of criminal law, 18 U.S.C.A. § 1116 makes it a crime to kill
or attempt to kill a “foreign official, official guest, or internationally protected person.” The term
“foreign official” includes, among others, a Chief of State or the political equivalent thereof while
he or she is in the United States. “Internationally protected person” covers, among others, a Chief
of State or the political equivalent thereof, whenever such person is in a country other than his or
her own. This criminal provision does not apply to the killing or attempted killing of an
internationally protected person in his or her own country. The United States courts may exercise
jurisdiction over the killing or attempted killing of internationally protected persons in violation
of 18 U.S.C. § 1116 committed outside the United States where the victim is a representative,
officer, employee or agent of the United States; where a perpetrator is a U.S. national; or where
an offender is later found in the United States.
In addition, Part 2.11 of Executive Order 12333 forbids any person employed by or acting on
behalf of the United States Government from engaging in, or conspiring to engage in,
assassination. Part 2.12 of that executive order further prohibits any agency of the Intelligence
Community from participating in or requesting any person to undertake activities forbidden by
the order. The executive order does not define “assassination,” nor does either the criminal statute
or the executive order specifically address the applicability of the prohibition to an armed conflict
in which the U.S. is engaged. However, in times of war, the targeting of an enemy’s command
and control structures may be regarded as strategically important, is lawful under international
law, likely is not intended to be barred by E.O. 12333, and does not appear to be covered by 18
U.S.C. § 1116. Hence, a declaration of war, because it creates a state of war regardless of whether
actual hostilities have occurred, arguably creates a situation where such an act is not prohibited by
domestic law. Less clear is the effect of an authorization for the use of force. Once a state of war
comes into existence following such an authorization, then the legal situation appears to be the
same as with a declaration. But prior to that development, the legal effect of an authorization for
the use of force on the assassination ban appears somewhat ambiguous.

121 For pertinent criteria and procedures applicable to such emergency situations, see 50 U.S.C. §§ 1805(e) (electronic
surveillance), 1824(e) (physical search), or 1843 (pen register or trap and trace device. This authority is applicable only
to gathering foreign intelligence information not concerning a United States person or information to protect against
international terrorism or clandestine intelligence activities, provided that such an investigation of a U.S. person may
not be conducted solely on the basis of First Amendment protected activities).
122 See, e.g., 50 U.S.C. § 1802 (electronic surveillance directed solely at acquisition of communications, not involving
U.S. persons, of a foreign government or governments or components thereof, factions of a foreign nation or nations
not substantially composed of U.S. persons, or entities openly acknowledged to be directed and controlled by a foreign
government or governments, without a court order for periods up to one year in specific circumstances; this provision
also covers electronic surveillance directed solely at acquisition of technical intelligence, other than spoken
communications of individuals, from property or premises of such foreign governments, factions, or entities). For a
more detailed discussion of FISA, see CRS Report RL30465, The Foreign Intelligence Surveillance Act: An Overview
of the Statutory Framework and U.S. Foreign Intelligence Surveillance Court and U.S. Foreign Intelligence
Surveillance Court of Review Decisions

Declarations of War and Authorizations for the Use of Military Force

An executive order may be revoked by the President through another executive order. To the
extent that an executive order is issued pursuant to authority granted by statute, Congress may
repeal it or terminate the underlying statutory authority upon which it rests. The assassination ban
is part of an executive order issued by President Reagan in 1981 under both statutory and
constitutional authority. The order does not indicate the nature of the authority underlying the
assassination ban in particular. If one were to argue that a statutory basis for the ban exists, then
one might contend that an authorization for a use of force would, by implication, modify the ban
or repeal it with respect to the context in which the use of force was authorized.
The Defense Production Act of 1950
Conversely, declarations of war or authorizations for the use of force do not appear to have any
particular consequences for the broad authorities conferred by the Defense Production Act of
1950 (DPA), as amended.123 The DPA was first enacted in 1950 to mobilize the nation’s
productive capacity after the outbreak of the Korean War. It currently plays a key role in enabling
the United States to maintain a national defense/military readiness capability that will support a
rapid and effective response to any threat to U.S. national security, including “an attack on the
United States.” The DPA has been reauthorized and amended a number of times, most recently in
2009. The original 1950 act contained seven titles, four of which were rescinded in 1953.124
Currently, three titles of the DPA are in effect, and they are due to expire on September 30, 2014,
unless renewed.125 The authorities contained in the act are not triggered by any particular event
but are continuously available “to ensure the national defense preparedness, which is essential to
national security ....”126
Title I (Priorities and Allocations)
This title127 provides the President with the authority to require the priority performance of
defense contracts and to allocate scarce critical and strategic materials essential to the national
defense. This authority may also be extended to support the military requirements of allied
nations when such extension is in the U.S. national defense interest. Priority contract
performance, especially as implemented with respect to industrial resources, is intended to ensure
sources of supply and timely delivery of required items for defense purposes.128
The post-Cold War use of this authority includes the 1990-1991 operations in the Persian Gulf
(Desert Shield/Storm). During this operation, such items as computer and communications

123 50 U.S.C.A. App. §§ 2061 et seq.
124 Titles II, IV, V, and VI pertained to Korean War-era economic stabilization measures (controlling prices, wages,
credit, etc.).
125 P.L. 111-67, § 2 (Sep. 30, 2009) extended the sunset date for these provisions from September 30, 2009 to
September 30, 2014.
126 50 U.S.C.A. App. § 2062.
127 Id. §§ 2071-2078.
128 Similar authority to require the priority performance of defense contracts, including those for the Nuclear
Regulatory Commission, if the President determines that “it is in the interest of national security” to do so, is conferred
by 50 U.S.C.A. App. § 468. That statute also authorizes the President to take immediate possession of any plant, mine,
or other facility that fails to honor such a priority requirement, including steel production facilities that fail to honor
priority directives regarding the apportionment of steel to entities producing steel products or materials for the armed
forces.

equipment, Global Positioning System receivers, chemical warfare protective clothing, and
medical supplies were urgently required by both U.S. and Allied nation forces. More recently,
DPA authority has been used to ensure timely delivery of critically needed items to support the
deployment of U.S. and NATO troops in Bosnia and nearby areas and the availability of natural
gas in California’s energy crisis in December, 2000, and January, 2001.
Title I contains a section that prohibits the President from exercising his priorities and allocations
authority unless he makes certain findings supporting the need for such action. Additional
sections provide the President with authority relating to the hoarding of designated materials,
penalties for the violation of any provision of Title I, small business preferences, etc.
Title III (Expansion of Productive Capacity and Supply)
This title129 is used only in cases where domestic sources are required and domestic firms cannot,
or will not, act on their own to meet a national defense production need. Because private firms
may be reluctant to invest in production capabilities for a new material unless a near-term demand
for the material is relatively certain, Title III authorizes the use of financial incentives to expand
defense-related productive capacity of critical components, critical technology items, and
industrial resources “essential to the national defense.” These financial incentives include loan
guarantees, direct federal loans, purchases, purchase guarantees, and installation of equipment in
contractor facilities. The authorities conferred in this title become broader in times of a national
emergency declared by the President or Congress.
Title VII (General Provisions)
This title130 includes various provisions with relevance to defense industrial preparedness.
Examples include (a) Section 708, which authorizes the President to provide antitrust defenses to
private firms participating in voluntary agreements aimed at solving production and distribution
problems involving national defense preparedness; (b) Section 710, which establishes a National
Defense Executive Reserve (NDER) composed of recognized experts from various segments of
the private sector and government (except full-time federal) employees for training for possible
employment in the federal government in the event of an emergency; and (c) Section 721, a
provision popularly known as the “Exon-Florio Amendment,” which authorizes the President to
suspend or prohibit the acquisition, merger, or takeover of a domestic firm by a foreign firm if
such action would threaten to impair national security.131
Insurance Contracts
Another domestic legal issue implicated by declarations of war and authorizations for the use of
force is their effect, if any, on insurance contracts, particularly with respect to clauses that exclude
coverage for “acts of war.” The overwhelming characterization of the events of September 11,
2001, as an “act of war” by public officials, sovereigns, international organizations, and the
media, for instance, caused concern that insurance companies and the courts would interpret so

Declarations of War and Authorizations for the Use of Military Force

called “war risk” exclusion clauses in the pertinent insurance contracts to deny claims related to
the attacks. However, even a declaration of war by Congress does not appear to have an
authoritative effect upon the construction of material terms contained in private contracts. The
intent of the parties, not the description of Congress, is what is most relevant to understanding
whether the events of September 11 or any future terrorist attacks constitute “acts of war” within
the meaning of private contracts,132 and it is not uncommon for such exclusion clauses in
insurance contracts to be given narrow constructions in order to allow recovery to the insured.133
In the leading case in this area, Pan American World Airways, Incorporated v. Aetna Casualty and
Surety Company,
134 a jet was hijacked and destroyed by political dissidents in the Middle East.
“Notwithstanding the obvious political overtones of the event,” the court ruled that “the hijacking
was too contained to come under the war or insurrection exclusion.”135 A rule of causation and a
rule of identity informed this conclusion. According to the Pan Am decision, when a court
interprets an insurance policy excluding from coverage any injuries “caused by” a certain class of
conditions, “the causation inquiry stops at the efficient physical cause of the loss; it does not trace
events back to their metaphysical beginnings.”136 In the Pan Am case, the court examined contract
language excluding from coverage losses caused by a “military or usurped power” and stated that
an act causing such a loss “must be at least that of a de facto government.”137 On the facts of the
case, the court then found that the terrorist organization that highjacked the Pan Am airplane “was
not a de facto government in the sky over London when the 747 was taken”138 and held that the
exclusion clause, therefore, did not apply.
This issue will not likely arise with respect to any future acts of terrorism on U.S. territory. In the
aftermath of September 11, 2001, Congress enacted the Terrorism Risk Insurance Act to ensure
the availability of commercial insurance coverage for losses due to acts of terrorism.139

personnel, and disability and death as the result of combat duty. None appear necessarily to
require a declaration of war to be applicable, but a declaration can trigger their application.
Crimes under the UCMJ
Various crimes defined under the Uniform Code of Military Justice (i.e., the UCMJ, set out at 10
U.S.C.A. §§ 801 et seq.) occur either primarily or exclusively in the context of states of hostilities
(e.g., “misbehavior before the enemy” under section 899; “subordinate compelling surrender”
under section 900; “improper use of countersign” under section 901; “forcing a safeguard” under
section 902; “aiding the enemy” under section 904; “misconduct as prisoner” under section 905;
and rules concerning “spies” under section 906). Several of these crimes either only occur or
occur in aggravated form “in time of war.”
The Manual for Courts Martial sets out Rules for Court Martial. Rule 103(19) defines the
expression “time of war,” as follows:
For purpose [sic] of ... implementing the applicable paragraphs of Parts IV and V of this
Manual only, “time of war” means a period of war declared by Congress or the factual
determination by the President that the existence of hostilities warrants a finding that a “time
of war” exists for purposes of ... Parts IV and V of this manual.140
Thus, a congressional declaration is not indispensable to prosecutions of these crimes but can
trigger their application. They do not appear to be triggered by an authorization for the use of
force unless a state of war develops. In the absence of a presidential or congressional declaration,
military courts have applied a variety of pragmatic tests to determine whether a “time of war”
existed in connection with specific offenses.141
For some offenses, the statutes of limitations may be tolled in “time of war.”142 When the United
States is “at war,” the statute of limitations on offenses involving fraud against the United States
or offenses committed in connection with U.S. property or procurement of contracts related to the
prosecution of the war is suspended until three years after the termination of hostilities (10
U.S.C.A. § 843(f)).143 These provisions have been held to apply during hostilities that were
initiated without a declaration of war or congressional authorization to use force.144

140 Part IV of the Manual for Courts-Martial implements the punitive articles of the UCMJ; Part IV implements non-
judicial punishment under art. 15, UCMJ.
141 See Joseph Romero , “Of War and Punishment: ‘Time of War’ In Military Jurisprudence and a Call for Congress to
Define its Meaning,” 51 Naval Law Review 1, 8-38 (2005).
142 10 U.S.C.A. § 843(a) eliminates the statute of limitations for absence without leave or missing movement in time of
war. Under 10 U.S.C.A. § 843(e),the President may extend the statute of limitations for any offense until six months
after hostilities end by certifying to the Secretary of Defense that a trial would be “detrimental to the prosecution of the
war or inimical to the national security.”
143 Military courts have not required a declaration of war in order for the suspension to apply, but rather, have applied
various tests to determine probable congressional intent in the context of the statute.

sleeping on post a capital offense); United States v. Ayers, 4 C.M.A. 220 (C.M.A. 1953) (statute of limitations tolled for
absence without leave in time war where offense was committed in the continental United States during the Korean
conflict); United States v. Taylor, 4 C.M.A. 232 (C.M.A. 1954) (statute of limitations tolled during Korean conflict
with respect to charge of fraud against the United States under 10 U.S.C.A. § 843(f).

Declarations of War and Authorizations for the Use of Military Force

The jurisdiction of the military expands during time of war. Prior to 2006, the UCMJ permitted
trial by court-martial of “persons serving with or accompanying an armed force in the field” in
time of war (10 U.S.C.A. § 802(a)(10)).When faced with the court-martial of civilians, courts
interpreted the phrase “in time of war” to mean only during wars declared by Congress.145
However, Congress amended 10 U.S.C.A. § 802(a)(10) to extend military jurisdiction in “time of
declared war or a contingency operation.”146 The provision has reportedly resulted in one
conviction of a civilian contractor in Iraq,147 a non-U.S. citizen whose Iraqi citizenship precluded
jurisdiction under the Military Extraterritorial Jurisdiction Act.148
In time of war or conditions of martial law, military commissions may provide a special venue for
trying persons not otherwise subject to the UCMJ.149 Military jurisdiction expands during war to
cover civilians accused of violating sections 904 or 906 (aiding the enemy and spying), as well as
other “offenders or offenses that by ... the law of war may be tried by military commissions,
provost courts, or other military tribunals” (§ 821), at least insofar as the Constitution permits.150
The Military Commissions Act of 2009, chapter 47A of Title 10, U.S. Code, permits the trial by
military commission of “alien unprivileged enemy belligerents” suspected of committing
violations against the law of war or “other offenses triable by military commission.”151 The
commissions may try such persons for offenses committed “before, on, or after September 11,
2001,”152 without any requirement for the authorization for the use of force in response to the
terrorist attacks of that date to have been in effect at the time the offense was committed. The
definition of “unprivileged enemy belligerent” is restricted to those who engaged in or
substantially supported hostilities against the United States or its coalition partners, except that
those who were members of al Qaeda at the time of the offense need not have such a connection
to hostilities.153 Thus, offenses defined by or under the jurisdiction of the Military Commissions
Act do not depend on a declaration of war or authorization to use force.

146 P.L. 109-364, § 552 (Oct. 17, 2006). “Contingency operation” is defined under 10 U.S.C. § 101(a)(13) to mean a
military operation that:
(A) is designated by the Secretary of Defense as an operation in which members of the armed
forces are or may become involved in military actions, operations, or hostilities against an enemy
of the United States or against an opposing military force; or
(B) results in the call or order to, or retention on, active duty of members of the uniformed services

Declarations of War and Authorizations for the Use of Military Force

Activation of Reserves
Chapter 1209 of title 10 of the United States Code (10 U.S.C.A. §§ 12301 et seq.) relates
generally to activation of reserve forces. The Ready Reserve forces include members of the Army
National Guard and the Air National Guard (see 10 U.S.C.A. § 10145(b)). The authority
conferred under sections 12302 through 12304 can be exercised without a congressional
declaration of war or national emergency; but those sections only allow reserve forces to be called
to active duty for fixed statutory periods (i.e., up to 24 consecutive months under sections 12302
and 12303 and up to 270 days under section 12304). By contrast, the authority conferred under
section 12301 can be exercised “[i]n time of war or of national emergency declared by Congress”
and allows reserve forces to be called to active duty “for the duration of the war or national
emergency and for six months thereafter.” The Standby Reserve (as distinguished from the Ready
Reserve and Selected Reserve forces) can only be called to active service under the authority
conferred by section 12301 (see section 12306). While the Retired Reserve can be called to active
service for up to 12 months under 10 U.S.C.A. § 688, it can be called to service “for the duration”
under the authority conferred by section 12301 (see section 12307). So-called “stop loss”
authority is conferred under section 12305. This authority allows the President, whenever persons
are called to active service under sections 12301, 12302, or 12304, to “suspend any provision of
law relating to promotion, retirement, or separation” with respect to any member of the armed
forces who the President determines is essential to the national security of the United States. This
means that, when persons have been called to active service under the authority conferred by
section 12301 “for the duration” of a war or national emergency declared by Congress, otherwise
applicable rules concerning promotions, retirements, and separations may not apply. Thus, for all
of these sections, a declaration of war is not a necessary predicate, but it can trigger the
application of section 12301 and related provisions. Reemployment rights for reservists called to
active duty available under the Uniformed Services Employment and Reemployment Rights Act
(USERRA, 38 U.S.C.A. §§ 4301 et seq.) and benefits available through the Servicemembers
Civil Relief Act (50 U.S.C.A. App. §§ 501—596) do not require a declaration of war, but depend
generally on the authority under which the call to active duty was made, and may vary according
to whether service was rendered during a period of war.
Coast Guard
Section 3 of title 14 of the United States Code specifies that “[u]pon the declaration of war if
Congress so directs in the declaration or when the President directs, the Coast Guard shall operate
as a service in the Navy ....”154 Thus, a congressional declaration of war is not indispensable to
bring the Coast Guard under the control of the Navy, but it would have that effect.
Tax Provisions
There are several provisions of the Internal Revenue Code which apply to taxpayers involved
directly or indirectly with war. A congressional declaration of war is not needed to render any of
these provisions applicable.
Perhaps the most significant relevant provision of the Internal Revenue Code is section 112 under
which some or all of the pay received by members of the uniformed services for active service in

154 The language “if Congress so directs in the declaration” was added by P.L. 109-241 (2006).

Declarations of War and Authorizations for the Use of Military Force

a combat zone is excluded from gross income (i.e., is received tax-free). The same exemption
applies to military pay received by service members hospitalized due to injuries sustained while
serving in a combat zone, subject to a two-year limitation. The term “combat zone” is specially
defined for purposes of this rule and means an area so designated by the President of the United
States in an Executive Order, and such an Executive Order must be issued to make the tax
exemption apply. No reference is made in this provision to any declaration by Congress of the
existence of a state of war and, by its express terms, it applied to service in the Korean and
Vietnam conflicts.
The pay of POWs and those listed as “missing in action” is also exempt (see (IRC § 112(d)).
In addition, pay received tax-free because of IRC § 112 is exempt from federal income-tax
withholding under IRC § 3401(a)(1). Qualified military benefits are exempt from tax under IRC §
134, and these include bonus payments made by a state or its political subdivision to a current or
former member of the Armed Forces, or to his or her dependents, by reason of service in a combat
zone designated under § 112. Due dates for filing returns and for paying taxes, according to IRC §
7508, are deferred for members of the uniformed services serving in a combat zone designated by
the President for purposes of IRC § 112. Telephone calls originating from combat zones
designated under IRC § 112 are exempt from the federal excise tax that would otherwise apply
(see IRC § 4253(d)). The so-called “additional estate tax” does not apply in the case of the estate
of a member of the Armed Forces who is killed in action in a combat zone designated under IRC
§ 112 or who dies as a result of wounds, disease, or injury suffered in such a combat zone (see
IRC § 2201).
An exemption from federal income tax for the current taxable year and any prior taxable year
ending on or after the first day of service in a combat zone and the preceding taxable year is
allowed under IRC § 692 for a member of the Armed Forces who dies in a combat zone
designated under IRC § 112 or who dies as a result of wounds, disease, or injury suffered in such
a combat zone. In addition, any unpaid taxes owed at the time of death will be forgiven. A similar
exemption is also allowed in the case of a civilian federal employee killed in any military action
involving the United States (see IRC § 692).
Special rules for spouses of persons who become missing in action also appear in the Code (see
IRC §§ 2(a)(3) and 6013).
Disability and Death
Subchapter II of chapter 11 of title 38 of the United States Code (38 U.S.C. §§ 1110 et seq.)
relates to “wartime disability compensation.” Relevant disability must result from personal injury
suffered or disease contracted in the line of duty in active military, naval, or air service “during a
period of war.”155 Thus, there is no explicit requirement of a congressional declaration of war. On
the other hand, such a declaration would obviously assure that the particular period of hostilities
in question is indeed a period of war. Some other veterans’ benefits depend on whether the person
seeking benefits served during a period of war.

155 For a list of “periods of war,” see CRS Report RS21405, U.S. Periods of War, by Barbara Salazar Torreon. For
information about requirements to qualify for veterans’ benefits, see CRS Report RL33113, Veterans Affairs: Basic

Declarations of War and Authorizations for the Use of Military Force

Chapter 13 of title 38 of the United States Code (38 U.S.C.A. §§ 1301 et seq.) relates to service-
connected deaths. Compensation in connection with such deaths is accorded without regard to
whether or not they occurred during or as a result of a war declared by Congress.
Rules under 38 U.S.C.A. § 2402 relating to the eligibility of members of the Armed Forces who
die while on active duty to be buried in national cemeteries (including Arlington National
Cemetery) and other rules concerning burial benefits are not contingent on a congressional
declaration of war.
Itemization of Standby Statutory Authorities
Under ordinary circumstances the President exercises the powers conferred on him by the
Constitution and by statutes enacted by Congress. As noted in the preceding section, in
extraordinary circumstances a number of additional statutory powers may become available; and
his Constitutional powers are likely to be given a generous interpretation by the courts. The
standby statutory authorities potentially available to the President and the executive branch
number in the hundreds. Some are triggered by a declaration of war, some by the existence of a
state of war (and, thus, also by a declaration of war), and some pursuant to a declaration or the
existence of national emergency. Most can be triggered by one or more of the foregoing
circumstances. None of these special authorities appears to be triggered by an authorization for
the use of force (unless and until it leads to a state of war). With respect to those statutes that are
triggered by the existence of a national emergency or of a state or time of war, the determination
of whether such a condition exists would be made in the first instance by the executive branch.
Those authorities that require a declaration of national emergency as a predicate for coming into
effect are not automatically activated by such a declaration. National emergency powers can be
exercised only pursuant to the strictures of the National Emergencies Act.156 In addition to
requiring that the President publicly declare a national emergency, that act requires that he specify
the emergency statutory authorities that he intends to use prior to their use and that he publish that
information in the Federal Register and report it to Congress.157 (On September 14, 2001,
President Bush, for example, took this step by issuing a “Declaration of National Emergency by
Reason of Certain Terrorist Attacks” and specifying 10 statutory authorities that he intended to
use.158) Moreover, the act provides that Congress can terminate a declared emergency at any time
by joint resolution and that, in any event, the emergency declaration and any statutory powers
activated pursuant to it expire after one year unless the President specifically renews the
declaration.159
The following subsections identify the standby authorities that become available to the President
and the executive branch upon (1) a declaration of war, (2) the existence of a state of war, and (3)
pursuant to a declaration of national emergency.160 It is important to emphasize that a declaration

of war activates not only the statutes listed in the first subsection but also—because a declaration

Many of following provisions can be triggered by circumstances other than a declaration of war.
But all would come into effect upon enactment of a declaration of war:
Congressional Budget Act
2 U.S.C.A. § 198(b)—provides that the rule mandating that Congress adjourn sine die by
July 31 of each year unless each House adopts a concurrent resolution, “shall not be
applicable in any year if on July 31 of such year a state of war exists pursuant to a
declaration of war by the Congress.”
2 U.S.C.A. § 641—provides that the requirement that amendments to a reconciliation bill not
increase budget outlays or decrease budget outlay reductions, revenues, or revenue increases
unless they include offsetting budget outlay reductions or revenue increases does not apply
“if a declaration of war by the Congress is in effect.”
2 U.S.C.A. § 642(a)—provides that the requirement making bills, amendments, motions, and
conference reports which provide new budget authority that would exceed what Congress
has set forth in the concurrent resolution on the budget for that fiscal year or that would
reduce revenues below what has been set forth in that concurrent resolution out of order in
the House does not apply “when a declaration of war by the Congress is in effect.”
2 U.S.C.A. § 643(b)(2)—provides that the requirement making any bill, amendment, motion,
or conference report that exceeds the discretionary spending limits set forth in 2 U.S.C.A.
App. 901(c) out of order in the Senate does not apply “if a declaration of war by the
Congress is in effect or a joint resolution pursuant to section 258 of the Balanced Budget and
Emergency Deficit Control Act of 1985 [2 U.S.C.A. § 907a] has been enacted”

Declarations of War and Authorizations for the Use of Military Force

2 U.S.C.A. § 907a(b-c)—states that sequestration reports and orders and certain other
requirements of the Budget Act are precluded or suspended “upon the enactment of a
declaration of war” but that the sequestration procedures are restored “effective with the first
fiscal year that begins in the session after the state of war is concluded by Senate ratification
of the necessary treaties ....”
Agricultural Exports
7 U.S.C.A. § 5712(c)—allows the President to prohibit or curtail the export of any
agricultural commodity “during a period for which the President has declared a national
emergency or for which the Congress has declared war.”
Armed Forces
10 U.S.C.A. § 123b—provides that the President may waive the statutory ceiling placed on
the number of members of the armed forces who may be stationed abroad in any fiscal year
“if the President declares an emergency” and that the ceiling “does not apply in the event of a
declaration of war or an armed attack on any member nation of the North Atlantic Treaty
Organization, Japan, the Republic of Korea, or any other ally of the United States.”
10 U.S.C.A. § 802(a)—subjects “persons serving with or accompanying an armed force in
the field ... in time of declared war or a contingency operation” to the Uniform Code of
Military Justice.
10 U.S.C.A. § 2350j(e)(3)(A)—allows the Secretary of Defense to carry out a military
construction project financed by contributions from designated countries or regional
organizations without prior explanation and justification to Congress if the project is
necessary to support the armed forces “by reason of a declaration of war, or a declaration by
the President of a national emergency pursuant to the National Emergencies Act that is in
force at the time of the commencement of the project.”
10 U.S.C.A. § 2662(g)—provides that the congressional notice and wait provisions
governing certain real property transactions by the Secretary of a military department and by
the GSA for the Department of Defense do not apply, inter alia, if the transaction results
from “a declaration of war ... or a declaration of a national emergency by the President
pursuant to the National Emergencies Act.”
10 U.S.C.A. § 2808(a)—provides that the Secretary of Defense and the Secretaries of the
military departments, with his authorization, may “without regard to any other provision of
law” undertake military construction projects “not otherwise authorized by law” if necessary
to support the use of the armed forces “in the event of a declaration of war or the declaration
by the President of a national emergency under the National Emergencies Act that requires
use of the armed forces.”
10 U.S.C.A. § 12311—provision for the Secretaries of the military departments to permit a

(2) Statutory Authorities Triggered by the Existence
of a State of War (and Thus Also by a Declaration
of War)

In addition to the statutes that are explicitly triggered by a declaration of war, a number come into
the effect if a state of war, or period of war, or simply “war” exists. Because a declaration of war
automatically creates a state of war, these authorities also are triggered by the enactment of a
declaration of war. But they can come into effect even if no declaration of war is adopted. As is
the case with respect to many of the statutes in the foregoing subsection, many of these statutes
can also be triggered pursuant to a declaration of national emergency, and at least one comes into
play if Congress has enacted a specific authorization for the use of the Armed Forces. The statutes
are set forth in the order in which they appear in the U.S. Code:
Administrative Procedure
5 U.S.C.A. § 551(1)—excludes “military authority exercised in the field in time of war or in
occupied territory” from the definition of “agency” for purposes of general administrative
procedure.

occupied territory” from the definition of “agency” for purposes of judicial review of

Federal Employees

employees be preserved for those employees whose civilian service is interrupted by “service
with the armed forces or by service in essential non-Government civilian employment during
a period of war or national emergency.”
5 U.S.C.A. § 5343(e)(3)—requires that step increases mandated for federal prevailing rate
employees be preserved for those employees whose civilian service is interrupted by “service
with the armed forces or by service in essential non-Government civilian employment during
a period of war or national emergency.”
5 U.S.C.A. § 8114(e)(3)—prohibits accounting for “bonus or pay for particularly hazardous
service in time of war” when computing pay to compensate government employees for work
injuries.
5 U.S.C.A. § 8332(g)—provides that a civil service employee who leaves his civilian
position to serve in the military “during the period of a war, or of a national emergency as
proclaimed by the President or declared by Congress” is deemed not to be separated from his
civil service position for purposes of determining his or her creditable service for retirement
purposes, unless the military service extends beyond 5 years.

renunciation as “not contrary to the interests of national defense.”

(3) Statutory Authorities Triggered by Declaration or
Existence of National Emergency

As noted, many of the statutes in the previous two subsections can also be triggered not only by a
declaration of war or the existence of a state of war but also by a declaration of national
emergency. There are, in addition, a number of statutes that can be triggered only upon a
declaration of national emergency or the existence of such an emergency. These standby
authorities do not automatically come into effect upon the issuance of a declaration of national
emergency but only in conformity with the procedures set forth in the National Emergencies Act.
The statutes, listed generally in the order in which they appear in the U.S. Code Annotated,
include the following:
Federal Employees
5 U.S.C.A. § 3326—allows retired members of the armed forces to be appointed to civil
service positions in the Department of Defense for 180 days after their retirement if “a state

Congressional Procedures for Declaring War or
Authorizing the Use of Force

The following section discusses how Congress would act on a joint resolution or bill to declare
war or authorize the use of force if the House and Senate were to consider that measure under the
regular procedures of each house. It also describes how a measure declaring war or authorizing
the use of force would be considered under the procedures contained in the War Powers
Resolution of 1973.165
Regular Procedures
The Senate’s published precedents do not suggest that a measure proposing to declare war or
authorize the use of force, if considered outside the framework of the War Powers Resolution,
would be immune from the potentially laborious process to which other bills and joint resolutions
are subject (except those that benefit from special expedited procedures under rule-making
statutes). For example, a joint resolution declaring war or authorizing the use of force presumably
would not be eligible for immediate floor consideration at the time it is introduced, and it
presumably would be subject to possible delays resulting from the Senators’ exercise of their right
to debate at length.
Similarly, the precedents of the House apparently do not grant privilege to a joint resolution
declaring war or authorizing the use of force either under the “leave to report” authority that
House rules and precedents give to certain House committees or as a question of the privileges of
the House. Concerning the latter, former House Parliamentarian Wm. Holmes Brown has
observed that “Rule IX [on questions of privilege] is concerned not with the privileges of the
Congress as a legislative branch, but only with the privileges of the House itself.” Thus, neither
the enumeration of legislative powers in Article I, sec. 8 of the Constitution nor the prohibition of
that article against any withdrawal from the Treasury except by enactment of an appropriation
renders a measure purporting to exercise or limit those powers a question of the privileges of the
House.166
Because a joint resolution declaring war or authorizing the use of force proposes to exercise a
constitutional power of “the Congress as a legislative branch,” not of the House alone, it would
seem, therefore, not to qualify as a question of privilege. If so, the House would consider the joint
resolution according to its established procedures for dealing with other legislative measures,167
unless the proposed declaration or authorization were to be considered under the terms of the War
Powers Resolution.
Congress has adopted eight declarations of war during the 20th century—two at the outset of U.S.
involvement in World War I and six in the course of World War II. House and Senate
consideration of the initial declarations in each of these wars is illustrative of the process that

Declarations of War and Authorizations for the Use of Military Force

Congress followed. On both occasions, the House and Senate acted to declare war in response to
urgent presidential requests made personally before joint sessions of Congress. In light of the
importance that most Members attached to these requests, it is not surprising that, in both cases,
the two houses acted on the joint resolutions quickly and without following all their regular
legislative procedures.
By way of illustration, the following is a brief summary of how the House and Senate considered
the initial joint resolutions to declare war in 1917 and 1941.
World War I
Congress convened on April 2, 1917, and on that evening, President Wilson addressed both
houses to request that Congress declare war against Germany. Immediately after the President’s
address, Senator Martin introduced S.J.Res. 1, to declare war, which was referred to the
Committee on Foreign Relations. Also on April 2, Representative Flood introduced a companion
resolution, H.J.Res 24, which was referred to the Committee on Foreign Affairs.
The Senate committee reported S.J.Res. 1 with an amendment on the following day. Senator
LaFollette objected to a unanimous consent request that the Senate consider the measure
immediately. Consequently, the joint resolution had to lie over for a day, pursuant to paragraph
4(a) of Senate Rule XVII. On April 4, the Senate agreed by unanimous consent to consider the
joint resolution, agreed to the committee amendment, and, after considerable debate, passed the
joint resolution by a roll call vote of 82-6.
The House committee reported H.J.Res. 24 on April 4, and the House then agreed, by unanimous
consent, to consider the measure on the following day “under the general rules of the House.”
Because the joint resolution, once reported, was placed on the Union Calendar, “the general rules
of the House” required that it be considered in Committee of the Whole. Consequently, when the
House convened on April 5, Representative Flood moved that the House resolve into Committee
of the Whole to consider H.J.Res. 24. Before the House agreed to his motion, however, it also
agreed to Representative Flood’s unanimous consent request that the House instead consider
S.J.Res. 1, which the Senate already had passed. After much debate, and after rejecting two
amendments in Committee of the Whole and a motion to recommit with instructions in the
House, the House passed S.J. Res. 1 by a roll call vote of 373-50.
World War II
On December 8, 1941, President Franklin D. Roosevelt addressed a joint session of Congress and
asked for a declaration of war against Japan. Immediately after the joint session ended, the Senate
reconvened and, following a live quorum call, Senator Connolly introduced a joint resolution
declaring war. At Senator Connolly’s request, and by unanimous consent, the Senate agreed to
consider the joint resolution immediately, without committee consideration. Within minutes, and
after brief statements by Senators Connolly and Vandenberg, the Senate passed the joint
resolution by a roll call vote of 82-0.
Also immediately after the President’s address, the House acted by considering and agreeing to
Representative McCormack’s motion to suspend the rules and pass H.J.Res. 254, which
Representative McCormack introduced at that time. December 8 being a Monday, suspension
motions were in order on that day. Immediately after the House passed H.J.Res. 254 by a roll call

vote of 388-1, the House received a message from the Senate that it already had passed its joint
resolution, now numbered S.J. Res. 116. The House then agreed to Representative McCormack’s
unanimous consent request that the House take the Senate joint resolution from the Speaker’s
table and agree to it. This action was necessary in order for both houses to pass the same measure,
making it eligible to be presented to the President for his signature.
Congressional Procedures Under The War Powers Resolution
Enactment of the War Powers Resolution in November 1973 created special expedited procedures
by which the House and Senate can act on joint resolutions or bills to declare war or authorize the
use of force, if those measures are considered in accordance with the other, related provisions of
that law.168
These expedited procedures were enacted into law as part of the War Powers Resolution as an
exercise of the constitutional rule-making powers of the House and Senate. Article I of the
Constitution empowers each house to set its own rules. When Congress enacts into law provisions
that affect only the internal operations of the House or Senate, or both, those provisions are
known as rule-making provisions of law that are enacted pursuant to this grant of power under
Article I. Such rule-making provisions have exactly the same force and effect as provisions
contained in the Standing Rules of the House and Senate.169 Consequently, the house to which
certain rule-making provisions apply may enforce, ignore, waive, suspend, supplement, or amend
them by its own unilateral action, as it sees fit. For example, the House could adopt a special rule,
or the Senate could agree to a unanimous consent request, that would supersede some or all of the
procedures described here.
Section 4(a) of the War Powers Resolution directs the President to submit a report to Congress
within 48 hours after U.S. armed forces are introduced “into hostilities or into situations where
imminent involvement in hostilities is clearly indicated by the circumstances.”170 Section 5(a)
provides for the receipt and for the referral to committee of any such presidential report. Under
Section 5(b), the President is required to terminate use of the armed forces within 60 calendar
days (90 days in some circumstances) after submitting his report unless Congress takes any one
of several actions. One of these actions is to declare war; another is to “enact a specific
authorization for such use of United States Armed Forces” as an alternative to declaring war.
Under another section of the War Powers Resolution, Congress can also adopt a bill or joint
resolution at any time requiring the President to remove the armed forces unless a declaration of
war or statutory authorization has been enacted.171

168 These expedited procedures are ambiguous in several respects. The description presented here should not be
considered a substitute for consultations with the House or Senate Parliamentarian.
169 Other examples of rule-making provisions of law are the various congressional procedures enacted as part of the
Congressional Budget and Impoundment Control Act of 1974 and related laws, and the “fast-track” provisions found in
the Trade Act of 1974 and related laws.
170 Presidential reports also are required under two other conditions enumerated in Sec. 4(a).
171 Prior to 1983, the WPR provided that Congress could mandate the removal of U.S. armed forces by adopting a
concurrent resolution. Given the virtual certainty that this procedure was unconstitutional following the Supreme
Court’s decision in June, 1983, in INS v. Chadha, 462 U.S. 919 (1983), Congress added a new provision to the War
Powers Resolution later in 1983 providing for expedited procedures for a bill or joint resolution to require the removal
of U.S. armed forces. See 50 U.S.C.A. § 1546a.

Declarations of War and Authorizations for the Use of Military Force

Section 6 of the War Powers Resolution contains the expedited, or “fast-track,” procedures that
were included in the law to enable the House and Senate to act within the 60 calendar-day period
on a bill or joint resolution contemplated by Section 5(b).172
If, under Section 6(a), such a measure is introduced at least 30 calendar days before the end of the
60-day period, the measure is referred to the House Foreign Affairs Committee or the Senate
Foreign Relations Committee, as the case may be. That committee is required to report one such
measure, with its recommendations, not later than 24 calendar days before the end of the 60-day
period. This provision suggests that the committee can report the measure with the committee’s
proposed amendments, if any. The subsection also provides that its provisions are to govern
“unless such House shall otherwise determine by the yeas and nays.” In other words, the House or
Senate can, by a rollcall vote decided by a simple majority, release its committee from the
obligation to report a measure proposing to declare war or to take some other action enumerated
in Section 5(b).
If the House or Senate committee does report, it is not required to report the measure favorably.
Instead, it may report it unfavorably or without recommendation. But what if either the Senate or
House committee fails to report a covered bill or joint resolution within the time permitted? The
Senate Parliamentarian has stated that the Senate Foreign Relations Committee would be
automatically discharged if it failed to report as required by this subsection. The House
Parliamentarian has stated that, should the House Foreign Affairs Committee fail to report in a
timely manner, a privileged motion to discharge that committee would be in order on the House
floor.
Section 6(b) governs initial House and Senate floor consideration of a joint resolution reported
from committee pursuant to Section 6(a). Under Section 6(b), the bill or joint resolution, once
reported (or once the committee is discharged), “shall become the pending business” of the House
or Senate, as the case may be. By making a covered measure the pending business on the House
or Senate floor, the War Powers Resolution evidently makes the measure privileged for floor
consideration in the House (without the need for the Rules Committee to report a special rule for
that purpose), or obviates the need for a motion (that usually is debatable) to proceed to the
measure’s consideration in the Senate. Because Section 6(b) contains no provisions to the
contrary, the measure presumably would be amendable on the floor of either house to the same
extent as any other bill or joint resolution that house considers, or could be tabled.
Section 6(b) goes on to require that the House or Senate vote on final passage of the measure
within three calendar days after having become the pending business, “unless such House shall
otherwise determine by yeas and nays.” The effect of this subsection probably is more significant
for the Senate than the House, because it is designed to preclude a filibuster on the Senate floor.
In addition, the last provision of the subsection evidently gives either house options to adjust the
timing and length of floor consideration by adopting any of several conceivable motions by
rollcall vote. For example, either house might agree by motion to postpone consideration of the
measure to a date certain. Alternatively, either house might dispose of the measure by a rollcall
vote in favor of a motion to table or recommit it or to postpone its consideration indefinitely.
Under the same authority, the House or Senate also might be able to shorten the debate to less
than three calendar days or to extend the time for debate.

172 A subsequent section of the WPR mandates expedited procedures for House and Senate consideration of a bill or
joint resolution requiring the removal of U.S. armed forces. See 50 U.S.C.A. §1546a.
Congressional Research Service

Declarations of War and Authorizations for the Use of Military Force

Sections 6(c) and 6(d) address the process for the House and Senate to reach agreement when
each has passed a measure covered by Section 5(b). In summary, Section 6(c) provides for
expedited committee and floor action in one house on a covered measure that the other house
already has passed. Finally, Section 6(d) states that if a conference is necessary to reach a
compromise between House and Senate versions of a covered measure, the conferees are to be
appointed “promptly,” the conferees are to report in either agreement or disagreement within
specified time periods, and the two houses are to act on the conference report before the end of
the 60-day period.
These last two subsections raise the problem that no rules or rule-making statute can compel the
House and Senate to reach agreement. All that expedited procedures can do is to require that the
conferees report, and that the House and Senate act on their report, by a time certain. The War
Powers Resolution cannot ensure that both houses will agree on the same position by the end of
the 60-day period. If the two houses were unable to agree by the end of the 60 days, that situation
presumably would be reflected in (1) votes by one or both houses to reject a conference report in
agreement, or (2) votes by both houses to agree to a conference report in disagreement (in other
words, votes in each house to accept the report of the conferees that they were unable to reach
agreement within the time allotted them). In either case, there is nothing in the statute that would
preclude the two houses from appointing a new conference committee that might present a new
conference report in agreement at some later date. However, a conference report filed in the
Senate after the expiration of the 60-day period might well be subject to extended debate because,
presumably, consideration of the report no longer would be governed by Section 6. Instead, the
report would be considered under the Senate’s regular procedures.

West Pacific Area and particularly of Formosa and the Pescadores; and
Whereas the secure possession by friendly governments of the Western Pacific Island chain, of
which Formosa is a part, is essential to the vital interests of the United States and all friendly
nations in or bordering upon the Pacific Ocean; and
Whereas the President of the United States on January 6, 1955, submitted to the Senate for its
advice and consent to ratification a Mutual Defense Treaty between the United States of America
and the Republic of China, which recognizes that an armed attack in the West Pacific area
directed against territories, therein described, in the region of Formosa and the Pescadores, would
be dangerous to the peace and safety of the parties to the treaty: Therefore be it
Resolved by the Senate and House of Representatives of the United States of America in Congress
assembled,

Armed Forces of the United States as he deems necessary for the specific purpose of securing and

area is reasonably assured by international conditions created by action of the United States or
otherwise, and shall so report to the Congress.

STATEMENTS OF POLICY
SEC. 5. (a) The Congress declares that the participation of the armed forces of other countries in
the Multinational Force in Lebanon is essential to maintain the international character of the
peacekeeping function in Lebanon.
(b) The Congress believes that it should continue to be the policy of the United States to promote

withdrawal of all foreign troops from Lebanon and establishing an environment which will permit
the Lebanese Armed Forces to carry out their responsibilities in the Beirut area.
(c) It is the sense of the Congress that, not later than one year after the date of enactment of this
joint resolution and at least once a year thereafter, the United States should discuss with the other

month period beginning on the date of enactment of this resolution unless the Congress extends
such authorization, except that such authorization shall terminate sooner upon the occurrence of
any one of the following:
(1) the withdrawal of all foreign forces from Lebanon, unless the President determines and
certifies to the Congress that continued United States Armed Forces participation in the
Multinational Force in Lebanon is required after such withdrawal in order to accomplish the
purposes specified in the September 25, 1982, exchange of letters providing for the
establishment of the Multinational Force in Lebanon; or

warrant, and nothing in this joint resolution shall preclude the Congress by joint resolution from
directing such a withdrawal.
(b) Nothing in this joint resolution modifies, limits or supersedes any provision of the War
Powers Resolution or the requirement of section 4(a) of the Lebanon Emergency Assistance Act

To authorize the use of United States Armed Forces against those responsible for the recent
attacks launched against the United States.

Whereas, on September 11, 2001, acts of treacherous violence were committed against the United
States and its citizens, and
Whereas, such acts render it both necessary and appropriate that the United States exercise its
rights to self-defense and to protect United States citizens both at home and abroad, and

Authorization of the Use of Force Against Iraq Resolution of 2002
(P.L. 107-243, 116 Stat. 1498, October 16, 2002 [H.J.Res. 114])
To authorize the use of United States Armed Forces against Iraq.
Whereas in 1990 in response to Iraq’s war of aggression against and illegal occupation of Kuwait,
the United States forged a coalition of nations to liberate Kuwait and its people in order to defend
the national security of the United States and enforce United Nations Security Council resolutions
relating to Iraq;
Whereas after the liberation of Kuwait in 1991, Iraq entered into a United Nations sponsored
cease-fire agreement pursuant to which Iraq unequivocally agreed, among other things, to
eliminate its nuclear, biological, and chemical weapons programs and the means to deliver and
develop them, and to end its support for international terrorism;
Whereas the efforts of international weapons inspectors, United States intelligence agencies, and
Iraqi defectors led to the discovery that Iraq had large stockpiles of chemical weapons and a large
scale biological weapons program, and that Iraq had an advanced nuclear weapons development
program that was much closer to producing a nuclear weapon than intelligence reporting had
previously indicated;
Whereas Iraq, in direct and flagrant violation of the cease-fire, attempted to thwart the efforts of
weapons inspectors to identify and destroy Iraq’s weapons of mass destruction stockpiles and
development capabilities, which finally resulted in the withdrawal of inspectors from Iraq on
October 31, 1998;
Whereas in P.L. 105-235 (August 14, 1998), Congress concluded that Iraq’s continuing weapons
of mass destruction programs threatened vital United States interests and international peace and
security, declared Iraq to be in “material and unacceptable breach of its international obligations”
and urged the President “to take appropriate action, in accordance with the Constitution and
relevant laws of the United States, to bring Iraq into compliance with its international
obligations”;
Congressional Research Service
103

Declarations of War and Authorizations for the Use of Military Force

Whereas Iraq both poses a continuing threat to the national security of the United States and
international peace and security in the Persian Gulf region and remains in material and
unacceptable breach of its international obligations by, among other things, continuing to possess
and develop a significant chemical and biological weapons capability, actively seeking a nuclear
weapons capability, and supporting and harboring terrorist organizations;
Whereas Iraq persists in violating resolution of the United Nations Security Council by
continuing to engage in brutal repression of its civilian population thereby threatening
international peace and security in the region, by refusing to release, repatriate, or account for
non-Iraqi citizens wrongfully detained by Iraq, including an American serviceman, and by failing
to return property wrongfully seized by Iraq from Kuwait;
Whereas the current Iraqi regime has demonstrated its capability and willingness to use weapons
of mass destruction against other nations and its own people;
Whereas the current Iraqi regime has demonstrated its continuing hostility toward, and
willingness to attack, the United States, including by attempting in 1993 to assassinate former
President Bush and by firing on many thousands of occasions on United States and Coalition
Armed Forces engaged in enforcing the resolutions of the United Nations Security Council;
Whereas members of al Qaida, an organization bearing responsibility for attacks on the United
States, its citizens, and interests, including the attacks that occurred on September 11, 2001, are
known to be in Iraq; Whereas Iraq continues to aid and harbor other international terrorist
organizations, including organizations that threaten the lives and safety of United States citizens;
Whereas the attacks on the United States of September 11, 2001, underscored the gravity of the
threat posed by the acquisition of weapons of mass destruction by international terrorist
organizations;
Whereas Iraq’s demonstrated capability and willingness to use weapons of mass destruction, the
risk that the current Iraqi regime will either employ those weapons to launch a surprise attack
against the United States or its Armed Forces or provide them to international terrorists who
would do so, and the extreme magnitude of harm that would result to the United States and its
citizens from such an attack, combine to justify action by the United States to defend itself;
Whereas United Nations Security Council Resolution 678 (1990) authorizes the use of all
necessary means to enforce United Nations Security Council Resolution 660 (1990) and
subsequent relevant resolutions and to compel Iraq to cease certain activities that threaten
international peace and security, including the development of weapons of mass destruction and
refusal or obstruction of United Nations weapons inspections in violation of United Nations
Security Council Resolution 687 (1991), repression of its civilian population in violation of
United Nations Security Council Resolution 688 (1991), and threatening its neighbors or United
Nations operations in Iraq in violation of United Nations Security Council Resolution 949 (1994);
Whereas in the Authorization for Use of Military Force Against Iraq Resolution (P.L. 102-1),
Congress has authorized the President “to use United States Armed Forces pursuant to United
Nations Security Council Resolution 678 (1990) in order to achieve implementation of Security
Council Resolution 660, 661, 662, 664, 665, 666, 667, 669, 670, 674, and 677”;
Congressional Research Service
104

Declarations of War and Authorizations for the Use of Military Force

Whereas in December 1991, Congress expressed its sense that it “supports the use of all
necessary means to achieve the goals of United Nations Security Council Resolution 687 as being
consistent with the Authorization of Use of Military Force Against Iraq Resolution (P.L. 102-1),”
that Iraq’s repression of its civilian population violates United Nations Security Council
Resolution 688 and “constitutes a continuing threat to the peace, security, and stability of the
Persian Gulf region,” and that Congress, “supports the use of all necessary means to achieve the
goals of United Nations Security Council Resolution 688”;
Whereas the Iraq Liberation Act of 1998 (P.L. 105-338) expressed the sense of Congress that it
should be the policy of the United States to support efforts to remove from power the current Iraqi
regime and promote the emergence of a democratic government to replace that regime;
Whereas on September 12, 2002, President Bush committed the United States to “work with the
United Nations Security Council to meet our common challenge” posed by Iraq and to “work for
the necessary resolutions,” while also making clear that “the Security Council resolutions will be
enforced, and the just demands of peace and security will be met, or action will be unavoidable”;
Whereas the United States is determined to prosecute the war on terrorism and Iraq’s ongoing
support for international terrorist groups combined with its development of weapons of mass
destruction in direct violation of its obligations under the 1991 cease-fire and other United
Nations Security Council resolutions make clear that it is in the national security interests of the
United States and in furtherance of the war on terrorism that all relevant United Nations Security
Council resolutions be enforced, including through the use of force if necessary;
Whereas Congress has taken steps to pursue vigorously the war on terrorism through the
provision of authorities and funding requested by the President to take the necessary actions
against international terrorists and terrorist organizations, including those nations, organizations,
or persons who planned, authorized, committed, or aided the terrorist attacks that occurred on
September 11, 2001, or harbored such persons or organizations;
Whereas the President and Congress are determined to continue to take all appropriate actions
against international terrorists and terrorist organizations, including those nations, organizations,
or persons who planned, authorized, committed, or aided the terrorist attacks that occurred on
September 11, 2001, or harbored such persons or organizations;
Whereas the President has authority under the Constitution to take action in order to deter and
prevent acts of international terrorism against the United States, as Congress recognized in the
joint resolution on Authorization for Use of Military Force (P.L. 107-40); and
Whereas it is in the national security interests of the United States to restore international peace
and security to the Persian Gulf region: Now, therefore, be it
Resolved by the Senate and House of Representatives of the United States of America in Congress
assembled,

Resolution of 2002.”

determination that—
(1) reliance by the United States on further diplomatic or other peaceful means alone either
