Armed Conflict in Syria: Overview and U.S. Response

Summary
The summer 2014 offensive in neighboring Iraq by the insurgent terrorist group known as the
Islamic State (IS, aka the Islamic State of Iraq and the Levant or ISIL/ISIS) has reshaped long-
standing debates over U.S. policy toward the three-year old conflict in Syria. The Islamic State
controls large areas of northeastern Syria, where it continues to clash with forces opposed to and
aligned with the government of Bashar al Asad. Meanwhile, fighting continues in other parts of
Syria, pitting government forces and their foreign allies against a range of anti-government
insurgents, many of whom also are engaged in battles with IS forces.
Since March 2011, the conflict has driven more than 3 million Syrians into neighboring countries
as refugees (out of a total population of more than 22 million). Millions more Syrians are
internally displaced and in need of humanitarian assistance, of which the United States remains
the largest bilateral provider, with more than $2.4 billion in funding identified to date. The United
States also has allocated a total of $287 million to date for nonlethal assistance to select
opposition groups. Prior to the Islamic State’s mid-2014 advances in Iraq, the Administration had
requested $2.75 billion in funding for the Syria crisis for FY2015.
Neither pro-Asad forces nor their opponents appear capable of achieving outright victory in the
short term. However, the prospect of international intervention to degrade the capabilities of the
Islamic State appears to be driving speculation among many parties to the conflict that dramatic
changes in the dynamics of what has remained a grinding war of attrition could soon be possible.
Some opposition forces seek to cast themselves as potential allies to outsiders who are opposed to
both the Islamic State and the Syrian government, while others reject the idea of foreign
intervention outright or demand that foreigners focus solely on toppling President Asad. Syrian
officials have stated their conditional willingness to serve as partners with the international
community in counterterrorism operations in Syria, a position that reflects their desire to create an
image and role for the Asad government as a bulwark against Sunni Islamist extremism.
For the United States and others examining options for weakening the Islamic State, these
conditions raise questions about how best to pursue new counterterrorism and regional security
goals without strengthening the Syrian government relative to the opposition groups and civilians
it has brutalized during the conflict. Similar questions arise in relation to options for countering
the Islamic State without bolstering other anti-U.S. Islamist groups. At present, anti-Asad armed
forces and their activist counterparts remain divided over tactics, strategy, and their long-term
political goals for Syria, with some powerful Islamist forces seeking outcomes that are contrary in
significant ways to stated U.S. preferences for Syria’s political future. The United Nations
Security Council also seeks continued Syrian government cooperation with efforts to verifiably
end Syria’s chemical weapons program. As of September 2014, all declared chemical weapons
had been removed from Syria, and all declared materials of priority concern had been destroyed.
Related facilities are set for destruction by March 2015.
Congress is now considering the President’s request for “train and equip” authority for vetted
Syrians under the pending continuing resolution H.J.Res. 124. For more information, see CRS
Report R43727, Proposed Train and Equip Authorities for Syria: In Brief, by Christopher M.
Blanchard and Amy Belasco. Senate committees have endorsed FY2015 defense appropriations
and authorization legislation (H.R. 4870/S. 2410) that also would support arming and training of
vetted opposition forces for select purposes.

Armed Conflict in Syria: Overview and U.S. Response

Overview
Fighting continues across Syria, pitting government forces and their foreign allies against a range
of anti-government insurgents, some of whom also are fighting amongst themselves. Government
forces are fighting on multiple fronts and have lost or ceded control of large areas of the country
since 2011, but hold most major cities in the western part of the country. The Asad government
continues to receive support from Russia, Iran, and Hezbollah. Contrary to some observers’
predictions, it has shown no indication of an imminent collapse or an intention to leave power.
Recent regime losses in confrontations with forces of the Islamic State (IS, aka the Islamic State
of Iraq and the Levant or ISIL/ISIS) in northeastern Syria may create new public pressure on the
government to improve military performance and leadership.
Opposition forces are formidable but lack unity of purpose, unity of command, and unified
international support. Various opposition groups have, depending on the circumstances,
cooperated and competed. At present, significant elements of the opposition are engaged in
outright conflict against one another. Much of the armed opposition seeks to replace the Asad
government with a state ruled according to some form of Sunni Islamic law, which non-Sunni
minority groups oppose. Kurdish groups control some areas of northeastern Syria and may seek
autonomy or independence in the future.
The Islamic State also controls large areas of the northeast, including most of the Euphrates River
valley and some areas adjacent to Syria’s borders with Turkey and Iraq. In conjunction with its
high-profile mid-2014 military offensive in Iraq, the Islamic State has worked to consolidate
control over its territory in Syria. Intensifying international and domestic debates now focus on
the Islamic State, the threats it may pose to regional and global security, and appropriate
international responses.
Meanwhile, chemical weapons inspectors work to oversee and implement the final requirements
associated with the September 2013 chemical disarmament agreement endorsed by the United
Nations (U.N.) Security Council in Resolution 2118. All of Syria’s declared chemical weapons
materials have been removed from the country and nearly completely destroyed. However, work
remains to be done to destroy specific chemical weapons-related facilities, amid ongoing
allegations of the use of chlorine gas by government forces. For more information on Syria’s
chemical weapons and U.S. and international participation in the disarmament process, see CRS
Report R42848, Syria’s Chemical Weapons: Issues for Congress, coordinated by Mary Beth D.
Nikitin.
For the moment, U.S. diplomatic efforts appear to be shifting away from efforts to achieve a
negotiated end to fighting and the establishment of a transitional governing body in Syria and
toward efforts to build regional and international consensus concerning responses to the rise of
the Islamic State. Some members of the Syrian opposition have expressed concern that
international efforts to combat the Islamic State will benefit the Asad government or undermine
international commitments to provide assistance to opposition groups seeking Asad’s ouster.
In Congress, Members are weighing the relative risks and rewards of direct action in Syria against
the Islamic State while considering a series of appropriations and authorization proposals that
could facilitate the potential provision of overt lethal security assistance to some vetted members
of select opposition groups, to include arms and training. Congress also may consider proposed
legislation to authorize, set conditions on, or prohibit the use of military force in Syria.

Armed Conflict in Syria: Overview and U.S. Response

In February 2014, Director of National Intelligence James Clapper estimated the strength of the
insurgency in Syria at “somewhere between 75,000 or 80,000 or up to 110,000 to 115,000
insurgents, who are organized into more than 1,500 groups of widely varying political leanings.”1
In spite of an apparent shared antipathy among opposition groups toward the brutality of the
Islamic State and the Asad government, many anti-Asad armed forces and their activist
counterparts remain divided over tactics, strategy, and their long-term political goals for Syria. As
of September 2014, the most powerful and numerous anti-Asad armed forces seek outcomes that
are contrary in significant ways to stated U.S. preferences for Syria’s political future.
Islamist militias seeking to enforce varying degrees of what they recognize as Sunni Islamic law
in Syrian society—among them members of the Islamic Front (see below), the Islamic State, and
Jabhat al Nusra (the Support Front)—have marginalized other armed groups, including some that
received U.S. nonlethal assistance. Earlier this year, U.S. intelligence community leaders
identified the approximately 26,000 members of ISIL, Jabhat al Nusra, and Ahrar al Sham
(Freemen of the Levant, a key component of the Islamic Front) both as extremists and as the most
effective opposition forces in the field. On September 3, National Counterterrorism Center
Director Matthew Olsen stated that as many as 12,000 foreign fighters have travelled to Syria,
including more than 1,000 Europeans, and more than 100 U.S. citizens.2 Previous U.S.
government assessments suggest that these fighters hail from more than 50 countries and that
among them are Al Qaeda-linked veterans of previous conflicts.
As clashes and diplomatic discussions continue, Syrian civilians continue to suffer in what U.S.
Director of National Intelligence James Clapper has described as an “apocalyptic disaster.” U.N.
sources report that since March 2011, the conflict has driven more than 3 million Syrians into
neighboring countries as refugees (out of a total population of more than 22 million; see Figure
1
). According to U.S. officials, more than 6.5 million Syrians are internally displaced. The United
States is the largest bilateral provider of humanitarian assistance, with more than $2.4 billion
allocated to date.3 In December 2013, the U.N. Office for the Coordination of Humanitarian
Assistance (UNOCHA) appealed for an additional $6.5 billion in humanitarian funding to
respond in 2014.4 For more information on humanitarian issues, see CRS Report R43119, Syria:
Overview of the Humanitarian Response
, by Rhoda Margesson and Susan G. Chesser.
The negative effects of the humanitarian and regional security crises emanating from Syria now
appear to be beyond the power of any single actor, including the United States, to independently
contain or fully address. The region-wide flood of Syrian refugees, the growth of armed extremist
groups in Syria, and the spread of conflict to neighboring Lebanon and Iraq are negatively
affecting overall regional stability. To date, policy makers in the United States and other countries
have appeared to feel both compelled to respond to these crises and cautious in considering
options for doing so that may have political and security risks such as the commitment of military
forces to combat or the provision of large-scale material assistance to armed elements of the
opposition. In light of these conditions and trends, Congress may face tough choices about U.S.
policy toward Syria and the related expenditure of U.S. relief and security assistance funds for
years to come.

Armed Conflict in Syria: Overview and U.S. Response

Anti-Asad Forces
Syrian Opposition Coalition and Select Armed Elements
Anti-Asad forces have been engaged in a series of realignments and internal conflicts since mid-
2013, creating complications for external parties seeking to provide support. To date, the United
States has sought to build the capacity of the Syrian Opposition Coalition (SOC) and local
activists. Many armed Sunni groups disavowed the SOC’s participation in the January-February
2014 “Geneva II” talks with the Asad government in Switzerland. The U.S. government has
recognized the SOC as the legitimate representative of the Syrian opposition and in May 2014
determined that the SOC’s representative office in the United States would be considered a
foreign mission pursuant to the Foreign Missions Act (22 U.S.C. 4301-4316).5
In July, the SOC elected Hadi Bahra, a Syrian businessman reportedly with close ties to Saudi
Arabia, as its new leader. Bahra served as a negotiator at the U.S.-backed peace talks in early
2014, and has been an outspoken critic of U.S. suggestions that the opposition’s disorganization
and infighting have contributed to its lack of success. In June 2014, Bahra argued, “The
expansion of cross-border extremism is a result of the reluctance of our friendly countries,
including the United States, to give sufficient support for the Syrian people and the mainstream
rebels to curb the rise of extremist groups and terrorist organizations that are being imported from
Syria’s neighboring countries.”6 Under Bahra’s leadership, the SOC continues to advocate for an
expansion of U.S. and other third-party support to opposition groups as a means of combating
extremist groups in Syria and pressuring the Asad government to agree to a negotiated settlement
to the conflict.

5 According to an unnamed Administration official, the determination will not grant personnel of the office diplomatic
immunity or convey control or ownership of Syrian state property under U.S. jurisdiction to the SOC. As of June 2014,
the United States government had not formally withdrawn diplomatic recognition from the government of Bashar al
Asad, although the State Department had expelled some Syrian diplomats from the United States.

Armed Conflict in Syria: Overview and U.S. Response

What is the “Free Syrian Army”?
The term “Free Syrian Army” is used by some Syrian and foreign supporters of opposition forces in Syria to refer to a
number of disparate armed groups who refer to themselves as members of the Jaysh al Hurr (the Free Army). Some
of these groups are outwardly secular and some may have Sunni Islamist leanings but express willingness to work with
secular groups. As of September 2014, the term “Free Syrian Army” does not correspond to an organized command
and control structure with national reach and unified procurement, intelligence, logistics, or sustainment capabilities.
Since 2011 uprising, there has been and continues to be no single military leader of the movement. At first, a number
of Syrian military defectors identifying themselves as leaders of the “Free Syrian Army” attempted to provide unified
leadership and build these types of capabilities for emergent opposition forces across Syria but were unable to exert
control over the actions of individual brigades. Regional and personal rivalries, the ascendance of Islamist armed
groups, and competing foreign patrons continue to undermine these efforts. A Supreme Military Council (see below)
formed in an attempt to overcome these challenges has proven incapable of overcoming them to date.
At present, a number of fighting groups actively refer to themselves as part of a broader “Free Syrian Army” while
carrying on operations independently. Several armed groups in southern Syria refer to themselves as “Free Syrian
Army” supporters and continue to claim attacks on Syrian government forces in Damascus, some of its surrounding
areas, and Daraa province. New attempts to unify the “Free Syrian Army” movement are being made from inside
Syria and from outside Syria. In northern Syria, five influential “Free Syrian Army” groups announced plans in
September 2014 to unite under a single command structure known as the Fifth Legion (the 101st Division, the 13th
Division, the First Brigade, the Fursan al Haq (Knights of Truth), and the Falcons of Jebel Zawiya). Syrian
Revolutionaries Front commander Jamal Maarouf (see below) also continues efforts to provide leadership to northern
fighting groups and actively refers to his forces as supporters of the “Free Army.”
The other major component of U.S. assistance has been the provision of nonlethal and lethal
support to armed groups, nominally in coordination with a Supreme Military Command Council
(SMC), whose leadership has been in flux for much of 2014. In June 2014, several military
officers reportedly resigned from the SMC, and SMC leader Brigadier General Abdul-Ilah al
Bashir al Noemi warned that U.S. support for individual armed groups risked creating
“warlords.”7 General Salim Idris, the former leader of the SMC, and other commanders rejected
leadership changes earlier in 2014 and distanced themselves from the SMC’s general staff and the
SOC’s then-defense minister. On June 26, the opposition’s interim government reportedly issued
a decision disbanding the SMC, a move rejected by Bashir and others. In July, the SOC voted to
dissolve the opposition’s interim government, and subsequent reports suggest that efforts to
reorganize the military command and its liaison mechanisms with the SOC are under way. SOC
President Bahra said in July 2014 that the SOC leadership had,
begun studying the absorption of the active rebel battalions within the SMC as a step towards
organizing the military efforts under one banner to counter to the growing threat of extremist
groups. It has become clear that Asad will not be forced to sit at the negotiating table unless
the military situation on the ground is changed in favor of the revolutionary forces, a thing
that can only be achieved through organizing the rebel factions into a unified body.8
Some reports suggest the Syrian Revolutionaries Front (SRF) and one of its prominent
commanders, Jamal Maarouf, or individual elements formerly associated with the SMC may be
emerging as focal points for new external assistance from the United States and others seeking to
back relatively moderate armed opposition forces. In August 2014, the SRF and other groups
announced the formation of a new Revolutionary Command Council to coordinate their efforts. It
remains to be seen how effective the new coordination body may be or how it may relate to
SOC/SMC related efforts to provide command and control over opposition forces. Since April

Armed Conflict in Syria: Overview and U.S. Response

2014, a coalition of militia forces known as Harakat Hazm (Resoluteness Movement) and several
other groups have released videos of their operatives loading and firing what appears to be U.S.-
origin anti-tank weaponry in Syria.9 Specific public information is lacking about sources of
weaponry and which units or personnel may have continuing access to U.S.-origin weaponry.10 In
August, the Islamist militia coalition known as the Ansar al Islam Front posted similar videos that
purport to depict their personnel firing U.S.-origin anti-tank weapons.11 An official affiliated with
Harakat Hazm told the New York Times that “friendly states” had provided “modest numbers” of
the weapons.12 The commander of the group told the Washington Post that those who supplied the
missiles had U.S. government approval and said the shipment “suggests a change in the U.S.
attitude toward allowing Syria’s friends to support the Syrian people.”13 In a September2014
interview, a Hazm movement member reportedly said, “we deal with Americans to alleviate the
suffering of our people, and not to fulfil America’s interests in our country.”14
Asked about the reported shipments and use of U.S. origin weaponry by Syrian rebels, U.S.
National Security Council spokeswoman Bernadette Meehan said, “The United States is
committed to building the capacity of the moderate opposition, including through the provision of
assistance to vetted members of the moderate armed opposition. As we have consistently said, we
are not going to detail every single type of our assistance.”15 On May 5, an unnamed senior
Administration official reiterated that formulation to members of the press in a background
briefing, while stating that “asymmetry which exists on the ground militarily, unfortunately,
between the regime and the moderate opposition is problematic for the emergence of the kinds of
political conditions necessary for a serious political process. And we and others are focused on
that.”16 In June, the Administration requested funding and authority to arm and train vetted
opposition forces after endorsing a Senate Armed Services Committee proposal contained in
Section 1209 of S. 2410. As discussed below (see “Proposed Expansion of Lethal and Nonlethal
Assistance”), President Obama has signaled his intention to expand assistance to select opposition
groups in Syria as a component of new efforts to combat the Islamic State.

In late 2013, a number of powerful Islamist militias—some of which formerly participated in the
structure of the SMC—announced the formation of a new Islamic Front.17 In early 2014, the

Armed Conflict in Syria: Overview and U.S. Response

Islamic Front and other opposition coalitions active in northern Syria moved to evict Islamic State
fighters from areas of northern and western Syria, and they remain engaged in hostilities with IS
forces in many areas. Prior to the outbreak of the confrontation with the Islamic State, many
expert observers considered the Islamic Front to be the most powerful element of the armed
opposition in northern Syria. The pressures of confrontation between members of the Islamic
Front and the Islamic State appear to have undermined the cohesion of the Front, as differences in
ideology, strategy, priorities, and preferred tactics have encouraged individuals, units, and groups
within it to reconsider their positions. In July 2014, Islamic Front member groups in Aleppo
announced their complete merger under the leadership of former Liwa al Tawhid (Monotheism
Brigade) leader Abdelaziz Salameh. Zahran Alloush, the military commander of the Islamic
Front-affiliated Jaysh al Islam (Army of Islam), continues to lead anti-regime operations in the
eastern suburbs of Damascus, where a coalition of armed Islamist groups recently agreed to form
a separate Unified Military Command. On September 9, an explosion and fire killed many of the
leaders of the powerful Ahrar al Sham Islamic Movement at a meeting in Idlib province, leading
many observers to speculate about the group’s future, in spite of its size and capabilities.
The Islamic Front’s November 2013 charter declared its goals to include “the full overthrow of
the Al Asad regime in Syria and for building an Islamic state ruled by the sharia of God Almighty
alone.”18 In that document, the Front explicitly rejected the concepts of secularism and a civil
state, rejected “foreign dictates,” and stated its commitment to maintaining the territorial integrity
of Syria. Front leaders have rejected the SOC and issued a statement on January 20 in conjunction
with the Mujahedin Army and another group rejecting the Geneva II talks and setting a series of
conditions that must be achieved before they will contemplate a settlement.19 The statement called
for “the entire regime, including its head and all its criminal figures” to step down and called for
security bodies to be held legally accountable. The Front and its allies further demanded that there
be “no interference in the form of the future state after the regime [steps down] and no imposition
of any matter that conflicts with the Islamic identity of the masses or which takes away the rights
of any section of society.” A “Revolutionary Code of Honor” issued by the Front and other groups
in May 2014 drew criticism from some hard-line Islamist figures for not explicitly calling for an
Islamic state for post-Asad Syria. The Islamic Front sought to forbid its supporters from
participating in the June 2014 presidential election, but also forbid attacks on polling stations and
encouraged its supporters not to consider voters to be infidels.
Jabhat al Nusra, an Al Qaeda-affiliated militia and U.S.-designated Foreign Terrorist
Organization, first sought to mediate between the Islamic State and its adversaries, but is now in
outright conflict with the group (see Figure 2 for a timeline of the emergence of the Islamic State
and Jabhat al Nusra). Their confrontation has sent shockwaves through the global jihadist
community as different clerics, armed group leaders, and individual supporters have declared
their respective views on the infighting. In general, other Syrian opposition forces have viewed
Jabhat al Nusra as more accommodating and cooperative than the Islamic State, including some
groups who oppose Jabhat al Nusra’s ideology. Some members of the Islamic Front and other

Armed Conflict in Syria: Overview and U.S. Response

non-Islamist opposition groups coordinate their operations with Jabhat al Nusra in different areas.
The pressures of combat against the Islamic State and the incompatibility of political goals among
the groups produce pressure for and against such coordination.
Secretary Kerry has accused the Asad government of “funding some of those extremists—even
purposely ceding some territory to them in order to make them more of a problem so he can make
the argument that he is somehow the protector against them.”20 Several press reports allege that
opposition groups have sold oil and petroleum products from areas under their control to agents
of the Syrian government. The Asad government’s past permissiveness toward anti-U.S. Sunni
extremist groups during the U.S. presence in Iraq and Asad’s release of several prominent
extremists from prison in 2011 raise further questions about the regime’s strategy.
The intra-opposition battles and the mid-2014 offensive launched by the Islamic State have drawn
increased global attention to the composition and direction of the Syrian opposition and the
provision of external support to its armed elements. The formation of the Islamic Front in
November 2013 raised questions about which forces actually remained affiliated with the SMC
and whether they are credible partners for the United States and others. Then, in December,
Islamic Front fighters took control of facilities and equipment belonging to the U.S.-backed SMC,
including some U.S.-supplied materiel. The incident, the Front’s rejection of the U.S.-preferred
strategy of negotiation, and the group’s long-term goal of establishing an Islamic state in Syria
raise fundamental questions about whether and how the United States should engage them.
In a January 2014 communiqué from their meeting in Paris, the United States and other members
of the “Friends of Syria core group of countries” (aka the “London 11” or “Core Group”)21 stated
that “all armed groups must respect democratic and pluralistic values, recognize the political
authority of the National Coalition [SOC] and accept the prospect of a democratic transition
negotiated in Geneva.... ”22 It remains to be seen whether statements by the Islamic Front and
others rejecting secular democracy, the political authority of the SOC, and negotiations with the
Asad government will preclude engagement by outsiders with the Front and its allies against the
Islamic State, Al Qaeda-affiliated groups, and/or against pro-Asad forces.
Threats Posed by Syria- and Iraq-Based Sunni Extremists
Since January 2014, U.S. officials have made several public statements describing the potential
for Syria-based extremists to pose terrorist threats to the United States. In particular, U.S. and
European officials have highlighted the threat that may be posed by foreign fighters, some of
whom hold U.S. and European passports. Central Intelligence Agency Director John Brennan said
in testimony before the House Permanent Select Committee on Intelligence in February 2014 that
there are three groups of people that are a concern, from an extremist standpoint; Ahrar al
Sham, Jabhat al Nusra, which is the Al Qaeda element within Syria, and the Islamic State of
Iraq and the Levant (ISIL). It’s those latter two I think are most dedicated to the terrorist
agenda. We are concerned about the use of Syrian territory by the Al Qaeda organization to
recruit individuals and develop the capability to be able not just to carry out attacks inside of

Syria, but also to use Syria as a launching pad. So it’s those elements—Al Qaeda and ISIL -
that I’m concerned about, especially the ability of these groups to attract individuals from
other countries, both from the West, as well as throughout the Middle East and South Asia,
and with some experienced operatives there who have had experience in carrying out a
global jihad.... There are camps inside of both Iraq and Syria that are used by Al Qaeda to
develop capabilities that are applicable, both in the theater, as well as beyond.23
Brennan called the threat posed by these groups “a near-term concern, as well as a long-term
concern,” and said that “the intelligence community, including CIA, is working very closely with
our partners internationally to try to address the terrorist challenge.”
In August 2014, the U.S. government supported the adoption of U.N. Security Council Resolution
2170, which strengthened international sanctions measures designed to combat the Islamic State,
Jabhat al Nusra, and Al Qaeda-affiliated entities. The resolution calls upon all Member States “to
take national measures to suppress the flow of foreign terrorist fighters to, and bring to justice, in
accordance with applicable international law, foreign terrorist fighters of, ISIL, ANF and all other
individuals, groups, undertakings and entities associated with Al Qaida,” and reiterates Member
States’ obligation to prevent terrorist travel, limit supplies of weapons and financing, and
exchange information on the groups. On September 5, Secretary of State John Kerry and
Secretary of Defense Chuck Hagel announced plans to “form a multinational task force to share
more information about the flow of foreign fighters into Syria and from Syria into Iraq,” saying,
“These foreign fighters represent an acute threat to our NATO allies.”24
The Islamic State (IS, aka the Islamic State of Iraq and the Levant, ISIL/ISIS)
The Islamic State is a transnational Sunni Islamist insurgent and terrorist group that has expanded
its control over areas of northwestern Iraq and northeastern Syria since 2013, threatening the
security of both countries and drawing increased attention from the international community.
In September 2014, National Counterterrorism Center Director Matthew Olsen stated that the
group poses “a direct and significant threat to us—and to Iraqi and Syrian civilians—in the region
and potentially to us here at home.”25 Olsen said “its strategic goal is to establish an Islamic
caliphate through armed conflict with governments it considers apostate—including Iraq, Syria,
and the United States.” Olsen further said that “we have no credible information that ISIL is
planning to attack the U.S.,” and highlighted potential threats posed by foreign fighters with
Western passports. According to Olsen, U.S. counterterrorism officials “remain mindful of the
possibility that an ISIL-sympathizer—perhaps motivated by online propaganda—could conduct a
limited, self-directed attack here at home with no warning.” However, Olsen noted that, “In our
view, any threat to the U.S. homeland from these types of extremists is likely to be limited in
scope and scale.” A CIA spokesperson provided an updated estimate of the IS organization’s size
in September 2014, saying the group could muster 20,000 to 31,500 individuals. Chairman of the
Joint Chiefs of Staff General Martin Dempsey told the Senate Armed Services Committee on
September 16 that two-thirds of the Islamic State organization’s personnel remain in Syria.

Armed Conflict in Syria: Overview and U.S. Response

In Syria, the Islamic State remains strongest in the province of Al Raqqah and in the eastern
provinces of Dayr az Zawr and Hasakah, adjacent to western Iraq. Its recent military operations in
Syria have focused on seizing control of Syrian government military bases in Al Raqqah
province, specifically the 93rd Brigade north of Al Raqqa city and the Taqba airbase. The
government-controlled Al Kuwayris airfield east of Aleppo also remained under siege. Islamic
State fighters continue to clash with other Syrian opposition forces in areas northeast of Aleppo
and remain engaged in combat with Syrian Kurdish militias and Arab tribal militias in Hasakah
and Dayr az Zawr provinces.
In Iraq, the Islamic State’s attempts to assert control over the cities of Fallujah and Ramadi in Al
Anbar province and its mid-2014 offensive across northern and western Iraq have underscored
the group’s lethality and ability to conduct combat operations and manage partnerships with local
groups in multiple areas over large geographic distances. Reports suggest that the Islamic State’s
possession of military weaponry and its willingness to use brutal tactics against its adversaries
contribute to the group’s ability to leverage its relatively limited size to control communities
through intimidation across a wide area. As of early September 2014, the Islamic State controlled
Mosul and areas west to the Syrian border, exercised control over areas of the Euphrates River
valley from the Syrian border to Abu Ghraib on the outskirts of Baghdad, and was conducting
intense military operations in communities along the Tigris River valley, including in Tikrit and
Sammara. The durability of the Islamic State’s partnerships is questionable given ongoing clashes
with other armed groups in Syria and past opposition to the Islamic State’s antecedents from Arab
tribes, other Islamists, Kurdish groups, and Baathists in Iraq.
Background
The group’s ideological and organizational roots (Figure 2) lie in the forces built and led by the
late Abu Musab al Zarqawi in Iraq from 2002 through 2006—Tawhid wal Jihad (Monotheism and
Jihad) and Al Qaeda in the Land of the Two Rivers (aka Al Qaeda in Iraq, or AQ-I). Following
Zarqawi’s death at the hands of U.S. forces in June 2006, AQ-I leaders repackaged the group as a
coalition known as the Islamic State of Iraq (ISI). ISI lost its two top leaders in 2010 and was
weakened, but not eliminated, by the time of the U.S. withdrawal in 2011. Under the leadership of
Ibrahim Awad Ibrahim al Badri al Samarra’i (aka Abu Bakr al Baghdadi),26 ISI rebuilt its
capabilities. By early 2013, the group was conducting dozens of deadly attacks a month inside
Iraq. The precise nature of ISI’s relationship to Al Qaeda leaders from 2006 onward is unclear. In
recent months, Islamic State leaders have stated their view that their group “is not and has never
been an offshoot of Al Qaeda,”27 and that, given that they view themselves as a state and a
sovereign political entity, they have given leaders of the Al Qaeda organization deference rather
than pledges of obedience.
In April 2013, Abu Bakr al Baghdadi announced his intent to merge his forces in Iraq and Syria
with those of the Syria-based Jabhat al Nusra, under the name the Islamic State of Iraq and the
Levant (ISIL/ISIS). Jabhat al Nusra and Al Qaeda leaders rejected the merger, underscoring
growing tensions among Sunni extremists in the region. In July 2013, ISIL attacked prisons at
Abu Ghraib and Taji in Iraq, reportedly freeing several hundred detained members and shaking
international confidence in Iraq’s security forces. ISIL continued a fierce wave of attacks across

26 Al Baghdadi was arrested and detained by U.S. forces in Iraq at Camp Bucca, until his release in 2009.

northern, western, and central Iraq, while in Syria the group consolidated control over the city and
province of Raqqa and expanded its presence in northwestern areas then controlled by other rebel
forces.
Late 2013 saw the Iraqi government seeking expanded counterterrorism and military assistance
from the United States, ostensibly to meet the growing Islamic State threat. Inside Syria, the
Islamic State alienated its rebel counterparts further, and an anti-IS campaign erupted there in
early 2014, expelling the group from some areas it had controlled and unleashing a cycle of
ongoing infighting. Following the launch of its mid-2014 assault in northern Iraq, ISIL changed
its name yet again to “the Islamic State” and announced the formation of a caliphate bridging
areas in its control in Iraq and Syria under the leadership of Abu Bakr Al Baghdadi.

Armed Conflict in Syria: Overview and U.S. Response

Ideology
Statements and media materials released by ISIL reflect an uncompromising, exclusionary
worldview and a relentless ambition. Statements by Abu Bakr al Baghdadi and ISIL’s spokesman
Abu Mohammed al Adnani feature sectarian calls for violence and identify Shiites, non-Muslims,
and unsupportive Sunnis as enemies in the group’s struggle to establish “the Islamic State” and to
revive their vision of “the caliphate.”28 The group describes Iraqi Shiites derogatorily as
“rejectionists” and “polytheists” and paints the Iraqi government as a puppet of Iran. Similar ire is
aimed at Syrian Alawites and the Asad government, although some sources allege that Islamic
State operatives have benefitted from evolving financial and security arrangements with
Damascus dating back to the time of the U.S. presence in Iraq.
In July 2012, ISIL leader Abu Bakr al Baghdadi warned U.S. leaders that “the mujahidin have set
out to chase the affiliates of your armies that have fled.... You will see them in your own country,
God willing. The war with you has just begun.”29 In January 2014, Al Baghdadi threatened the
United States directly, saying, “Know, O defender of the Cross, that a proxy war will not help you
in the Levant, just as it will not help you in Iraq. Soon, you will be in direct conflict—God
permitting—against your will.”30 English language propaganda and recruiting material released
by the group in connection with its recent executions of U.S. citizens James Foley and Stephen
Sotloff suggest the group is attempting to portray itself as responding to U.S. aggression, a
posture adopted by its predecessors and now rivals in Al Qaeda.
Potential Effects of Islamic State Operations in Iraq on Syria31
IS gains in Iraq are likely to facilitate the flow of weapons and fighters into eastern Syria to the
Islamic State and other groups, and may increase bilateral cooperation between the Iraqi and
Syrian governments. Captured U.S.-origin military equipment provided to Iraqi security forces
has appeared in photos reportedly taken in Syria and posted on social media outlets. Islamic State
advances in Iraq could weaken the Syrian government’s ability to hold ground in contested areas,
as some Iraqi Shia militants who had previously fought alongside Asad forces return home to
combat IS forces.32 Syrian forces reportedly conducted air strikes against IS-held areas of Raqqah
and Hasakah in coordination with the Iraqi government, according to the London-based Syrian
Observatory for Human Rights.33 Increased cooperation between Damascus and Baghdad could
alter the dynamics in both conflicts. It could undermine ongoing U.S. efforts to encourage Iraqi
leaders to press Asad to step down in favor of a transitional government. Increased Iraqi-Syrian
cooperation could also make Baghdad less likely to comply with U.S. requests to crack down on
Iranian overflights of weapons and equipment to Damascus.

Armed Conflict in Syria: Overview and U.S. Response

It is unclear what impact IS gains in Iraq would have outside of eastern Syria. At least half of
Syria-based IS fighters are Syrian or Iraqi tribesmen, according to a Syrian IS defector.34 Like
other segments of the Syrian opposition, Syrian tribes have at times been reluctant to expand
engagement with government forces beyond their own local areas. Since early 2014, the Islamic
State has concentrated its forces in Syria’s northeast, and has largely avoided regular
confrontations in the country’s main urban areas in Syria’s western half. Any Iraqi or U.S. efforts
to disrupt or sever IS supply lines linking eastern Syria and western Iraq could benefit Syrian
military and Al Qaeda-affiliated Jabhat al Nusra forces also operating in the area.
Pro-Asad Forces35
The Syrian government has continued military and security operations against insurgents while
pursuing political measures intended to boost Asad’s domestic and international legitimacy.
Government forces continued operations throughout Western Syria in an effort to isolate rebels
and sever their supply lines.36 The government since the beginning of the year has also conducted
more than 40 local truces with rebel groups in besieged areas of Damascus, the Damascus
countryside, and Homs that have allowed it to gain greater control in some contested areas.37
On August 25, Syrian Foreign Minister Walid al Muallem at a news conference in Damascus
emphasized the regional threat from terrorist groups such as the Islamic State, and stated that
Damascus was open to counterterrorism cooperation with the West as long as any operations were
coordinated with the Syrian government. Muallem added that coordination would also serve to
“prevent a misunderstanding. This is because we have air defense systems. Unless there is
coordination, we might get to this point.”38 However, some observers contend that Syria’s air
defense network provides uneven coverage—heaviest in areas around Damascus and minimal in
the sparsely populated northeast where the Islamic State is most prevalent.39
Prior to the Islamic State’s rapid territorial advance in the summer, some observers suggested that
the Asad government had not devoted significant resources to countering the group—in part
because its presence supported the government’s characterization of the opposition as dominated
by extremists. The government also appeared to see some benefit in the Islamic State’s tendency
to combat other Syrian opposition groups.40 However, as the Islamic State increased attacks on
isolated military outposts in the northeast, Syrian forces in August stepped up airstrikes against IS
positions in Aleppo, Raqqah, Dayr az Zawr, and Hasakah provinces.41 Despite its use of airpower

against the Islamic State, the military’s concentration of ground forces in western Syria appears to
have significantly limited its ability to recover territory in the country’s northeast.
Asad in July was sworn in for a third seven-year term as president after winning elections
condemned as illegitimate by Syrian oppositionists, the United States, and the European Union. 42
Elections were held in all provinces except Raqqah in northern Syria, which remains under the
control of the Islamic State.43 Syrian government officials reported that Asad won with 88.7% of
the vote—falling short of the 97% victory he claimed in the 2007 presidential referendum.44
Opposition leaders were effectively disqualified from running by Syria’s revised election law,
which stipulates that candidates must have maintained continuous residence in Syria for 10 years
prior to nomination and hold no other nationality or prior criminal convictions.45 Syria’s Supreme
Constitutional court put voter turnout at 73.4%, although some Asad opponents stated that they
voted primarily to avoid retribution.46 Syrian oppositionists, as well as the United States and the
European Union, condemned the vote as illegitimate.47
The United States and other members of the Core Group on Syria had previously rejected Asad’s
candidacy, noting that a decision to hold presidential elections was inconsistent with the Geneva
Communique’s call for the establishment of a transitional governing body.48 Although the Syrian
government participated in the Geneva II negotiations in early 2014, its representatives insisted
that counterterrorism issues be addressed before any discussion of a potential transition. Asad
appears disinclined to make concessions that would significantly undermine his hold on power,
particularly if he assesses that his military ultimately can prevail over insurgents or at least hold
them at bay. Asad may judge that his move to declare and destroy his government’s chemical
weapons has eased international pressure on his government. Syrian officials may also hope that
Western fears of Islamic State expansion in the region could lead to renewed cooperation with the
Asad government, bolstering its legitimacy.
Shia Armed Groups and Iranian Support for the
Syrian Government

The involvement of Shia militias and Iran in the Syrian conflict has evolved since 2011 from an
advisory to an operational role, with forces in some cases fighting alongside Syrian troops.
Lebanese Hezbollah and Iran have traditionally depended on the presence of a friendly
government in Damascus to facilitate the transit of weapons from Iran to Hezbollah and to
preserve their ability to challenge Israel. Hezbollah and Iranian roles in Syria appear designed to
bolster Asad’s ability to suppress the opposition but also to secure their interests in Syria in the
event that the Asad government does not survive.49

Armed Conflict in Syria: Overview and U.S. Response

Hezbollah
In August 2012, the U.S. Treasury Department sanctioned Hezbollah for providing training,
advice, and logistical support to the Syrian government.50 U.S. officials also noted that Hezbollah
has helped the Syrian government push rebel forces out of some areas in Syria. Hezbollah
Secretary General Hassan Nasrallah, who was personally sanctioned for his role in overseeing
Hezbollah’s assistance to Damascus, publicly acknowledged Hezbollah’s involvement in Syria in
May 2013. Nasrallah also recently expressed confidence that the risk of the Asad regime’s defeat
and the partition of Syria had passed even if a war of attrition may persist.51 He further referred to
the need for reconciliation initiatives to bolster the Asad government’s support among Syrians.
As of September 2014, Hezbollah fighters remained engaged in operations in the Qalamoun
region northwest of Damascus, where the departure of some Iraqi paramilitary forces could place
additional pressure on the group.52 The London-based Syrian Observatory for Human Rights in
August reported that at least 561 Hezbollah fighters had been killed in Syria since early 2013.53 A
senior Israeli military official in March 2014 stated that Hezbollah currently maintains 4,000 to
5,000 fighters in Syria.54
Over the past year, Hezbollah has worked with the Syrian military to protect regime supply lines
by helping to clear rebel-held towns along the Damascus-Homs stretch of the M-5 highway.55
Hezbollah personnel in 2013 played significant roles in battles around Al Qusayr and the
Qalamoun Mountains region, in which rebel presence along the highway threatened the
government’s ability to move forces and to access predominantly Alawite strongholds on the
coast.56 Hezbollah forces on the Lebanese side of the border reportedly monitor and target rebel
positions near the border that facilitate attacks in Syria and Lebanon.
Last year saw an uptick in violence against Hezbollah targets in Lebanon, and the militia’s
support for the Asad government appears to be contributing to the rise in sectarian violence and
tension in Lebanon. Jabhat al Nusra and ISIL have claimed responsibility for attacks on
Hezbollah-controlled areas of Beirut and eastern Lebanon, describing the attacks as retaliation for
Hezbollah’s intervention in Syria.57
Iraqi Militias
Analysts estimate that there are between 2,000 and 5,000 Iraqi Shia fighting in Syria on behalf of
the Syrian government.58 Many hail from Iraqi Shia political and militia groups including Asa’ib

Ahl al Haq and Kata’ib Hezbollah. Members identify their objective as the defense of Shia holy
sites such as the tomb of Sayyida Zeinab, the granddaughter of the Prophet Mohammad, in
southern Damascus. Other reports describe these groups as assuming a broad operational role,
noting that militias have formed sniper teams, led ambushes, established checkpoints, and
provided infantry support for Syrian armored units.59
It is difficult to assess the motivations of individual Iraqi fighters in Syria or determine whether
Asad’s survival is their primary goal. Some of the fighters appear to be young volunteers driven
by a desire to protect Shia holy sites, while others are trained militiamen who previously fought
coalition forces in Iraq. Reports suggest that Iraqi fighters receive training in Iran before being
flown in small batches into Syria, and that they work closely with Lebanese Hezbollah.60
However, it is unclear who ultimately exercises command and control over these militias. Clashes
between Iraqi and local Syrian militias in mid-2013 resulted in some Iraqi combatants refusing to
fight under Syrian command.61 Recent gains by ISIL in Iraq have prompted some Iraqi fighters in
Syria to return home and join local militias.62
Iranian Support
Since 2011, Iran has provided technical, training, and financial assistance both to the Syrian
government and to pro-regime Shia militias operating in Syria. In February 2012, the U.S.
Treasury Department sanctioned the Iranian Ministry of Intelligence and Security (MOIS) for
providing substantial technical assistance to Syrian intelligence, noting that MOIS also
participated in multiple joint projects with Hezbollah.63 Treasury also designated the Islamic
Revolutionary Guard Corps-Quds Force (IRGC-QF) for training Syrian forces, and Iraqi Shia
militias fighting in Syria have credited Iran for providing training and coordinating their travel
into the country. Mohammad Ali Jafari, head of the IRGC, acknowledged in September 2012 that
some members of the Quds Force were present in Syria,64 and U.S. officials have described them
as also working closely with Hezbollah. Regional observers in March 2014 estimated that
between 1,000 and 1,500 IRGC members were present in Syria.65 In terms of nonlethal aid, Iran
has provided Syria with billions of dollars in credit to purchase oil, food, and import goods
from Iran.66
Chemical Weapons and Disarmament67
A major policy concern of the United States has been the use or loss of control of chemical
weapons stocks in Syria during the ongoing civil war. The United States and other countries have
assessed that the Syrian government has used chemical weapons repeatedly against opposition

forces and civilians in the country. Syria is believed to have possessed more than 1,000 metric
tons of chemical warfare agents and precursor chemicals. This stockpile included several hundred
metric tons of the nerve agent sarin, which represented the bulk of Syria’s chemical weapons
stockpile. Damascus also had several hundred metric tons of mustard agent in ready-to-use form
and several metric tons of the nerve agent VX.68
The largest-scale use to date was reportedly an attack using nerve gas on August 21, 2013, which
the U.S. government estimated killed over 1,400 people.69 The U.N. Mission to Investigate
Allegations of the Use of Chemical Weapons in the Syrian Arab Republic released its report on
September 16, 2013, concluding that surface-to-surface rockets containing the chemical weapons
nerve agent sarin were used in the Ghouta area of Damascus against civilians on a “relatively
large scale.” The U.N. investigative mission was not tasked with assigning culpability for the
attacks.
Chlorine gas attacks in northern Syria have been repeatedly reported since mid-April 2014. The
OPCW established a Fact-Finding Mission to investigate these allegations. In their second report
released on September 10, the investigators concluded they have “compelling confirmation” that
a toxic chemical was used “systematically and repeatedly” as a weapon against villages in
northern Syria.70 The Fact-Finding Mission concludes that “chlorine, either pure or in mixture”
was used in attacks on the villages of Talmanes, Al Tamanah, and Kafr Zeta. The report’s findings
are based on interviews and other evidence. The mission came under attack gathering evidence
onsite in May. Chlorine is not required to be declared or destroyed under the Chemical Weapons
Convention (CWC), although its use in warfare is still prohibited under the Convention.
By mid-August 2014, the international community had removed and destroyed Syrian declared
chemical weapons stocks, including nerve agents. A year earlier, in August 2013, the Obama
Administration had threatened military action against Syria in response to alleged nerve gas
attacks by Syrian government forces. As part of a diplomatic solution to the crisis based on a
U.S.-Russian joint proposal, the Administration withdrew the threat of military force and Syria
agreed to give up its chemical weapons and join the international Chemical Weapons Convention
(CWC), which bans the use of any toxic chemicals in warfare and requires Syria to destroy all of
its chemical weapons stocks and production facilities under international supervision. The
Executive Council of the OPCW, an intergovernmental body tasked with implementation of the
CWC, approved a destruction plan under which Syria was required to destroy all chemical
weapons by June 30, 2014. According to the Director General, Syria did not meet the June 30
deadline for destruction of all chemical weapons and production facilities,71 but all declared
chemical weapons agents had been removed from the country as of June 23, 2014. One hundred
percent of the most dangerous “priority” chemical weapons agents declared by Syria had been
destroyed by August 8, 2014, and 96% of all other chemicals.72 However, despite this progress,

destruction of facilities is still underway, and the United States has raised questions over whether
Syria has declared all of its chemical weapons.
Removal of Chemicals
A joint mission of U.N. and OPCW personnel was created to monitor and facilitate Syrian
chemical weapons disarmament.73 OPCW-U.N. experts arrived in Damascus on October 1, 2013,
and began to inspect Syria’s declared chemical weapons facilities. The first stage of destruction
activities focused on destroying “critical equipment” at chemical weapons production facilities.
The OPCW spokesman told reporters on October 31, 2013, that the Syrian government met the
deadline for disabling production equipment, and that all chemical weapons stocks and agents in
Syria were under “tamper-proof” seal.
The second stage of the chemical weapons destruction process involved transportation and
removal of chemical weapons agents from the country. These were liquid chemicals that have not
been loaded into delivery vehicles. The OPCW Executive Council on November 14, 2013,
approved the destruction of Syria’s chemical weapons agents (“priority 1” chemicals) outside of
Syria due to the security situation in the country. The United States and others provided
equipment to the OPCW-U.N. Joint Mission to help safely transfer these chemicals from storage
facilities to the Syrian port of Latakia. Once the chemicals arrived at the port, Danish and
Norwegian ships picked up the chemicals and removed them from Syria. The first quantity of
priority chemicals was moved to the port of Latakia in early January 2014, and the last shipment
was on June 23, 2014. This was the first time all of a country’s declared chemical weapons agents
have been removed from its territory.
While this task was completed in six months, Syria had repeatedly missed several previous
deadlines. According to the OPCW Director General, the delays were caused by “security
concerns, the procurement and delivery of large quantities of packaging and transportation
materials and equipment, and adverse weather conditions.”74 There was active military
engagement in the areas near storage sites. These delays raised questions about the intentions of
the Syrian government. In February, the U.N. Security Council called upon Syria to expedite
removal of the chemicals. The United States in particular had been critical of the slow progress by
the Syrian government. As U.S. Ambassador to the OPCW Robert Mikulak said,
The international community has put into place everything that is necessary for transport and
destruction of these chemicals. Sufficient equipment and material has been provided to Syria.
The ships to carry the chemicals away from Syria are waiting. The U.S. ship to destroy CW
agent and precursors is now in the region and waiting. Commercial facilities to destroy other
chemicals have been selected and contracts awarded; they are waiting. And yet Syria
continues to drag its feet.75
In March, OPCW-U.N. Joint Mission Special Coordinator Sigrid Kaag described “important
progress” in efforts to expedite the transfer and destruction of chemicals and encouraged the

Syrian government “to sustain the current pace.”76 On April 29, the Joint Mission estimated that
the Syrian government had moved 18 shipments of chemicals to the port of Latakia, representing
around 92.5% of total stocks to be removed (up from 53.6% in mid-March).77 Ambassador
Mikulak on April 29, 2014, said that “almost 100 tons of Priority 1 and Priority 2 chemicals still
remain in Syria.” He also said that the storage site where the remaining stocks were located was
occupied by Syrian government forces and therefore packing and preparation for transport should
have started immediately.78 Fighting in the region of the site, which is northeast of Damascus, had
raised concerns about the overland transportation of the materials. The Syrian government said
the material could not be moved due to security concerns in the surrounding area. However, on
June 23, 2014, the OPCW announced that it had supervised the removal of the final shipment of
chemicals to the port of Latakia and they were successfully transferred and removed from the
port.79
Destruction of Chemical Weapons Outside of Syria
No country had agreed to conduct destruction operations on its territory due to public concerns
about the dangers of the material, but also due to the short timeline for destruction which in some
cases would not have allowed for the required environmental and health impact assessments.
Therefore, the United States offered to neutralize the liquid chemical weapons agents on board
the Maritime Administration’s Motor Vessel (MV) Cape Ray using newly installed field
deployable hydrolysis systems (FDHS). This ship received 600 metric tons of both mustard agent
and DF compound, a key component in sarin.80 U.S. personnel, including 64 Army chemical
specialists, ran the operation. Once removed from Latakia, the most dangerous compounds in
approximately 60 containers were transferred to the Cape Ray at the Italian port of Gioia Tauro
for destruction at sea in international waters. Less sensitive chemicals will be shipped to
commercial processing facilities in Finland, the United Kingdom, and the United States.
Companies in Finland and the United States were awarded contracts for processing the liquid
waste from the destruction process.81
As of July 24, 2014, all 1300 metric tons of chemicals removed from the Syrian Arab Republic
had been successfully delivered to destruction facilities outside of Syria.82 On July 2, 2014, 600
metric tons of Priority 1 chemical weapons were successfully loaded onto the U.S. vessel MV
Cape Ray
in the port of Gioia Tauro, Italy. The destruction of the chemical weapons onboard was

completed on August 18, 2014. This included 581 metric tons of DF, and 19 metric tons of sulfur
mustard.83
The remaining 700 metric tons of chemicals have been successfully delivered to Riihimaki,
Ellesmere Port, and Port Arthur, Texas—commercial land-based facility locations in Finland, the
United Kingdom, and the United States, respectively. On August 7, 2014, the United Kingdom
announced that it destroyed its consignment of chemical weapons from Syria—190 metric tons of
Priority 1 chemicals—at Ellesmere Port.84
Destruction of Production Facilities
The Syrian government did not meet the deadline of March 15, 2014, for destruction of its 12
declared chemical weapons production facilities, and has proposed that the underground facilities
not be completely destroyed but instead made inaccessible.85 The CWC requires that production
facilities be “physically destroyed.” U.S. Ambassador to the OPCW Robert Mikulak said in a
February statement that the Executive Council should require Syria to physically destroy the
facilities in line with the Convention.86 The OPCW has been developing a destruction plan for
these facilities with Syria. Ambassador Mikulak said in a statement on April 29, 2014, that 12
chemical weapons production facilities declared by Syria remain “structurally intact.” Syria had
first requested that the facilities be converted for other military purposes. Mikulak noted that
Syria should be held to the same standards as other countries that have destroyed their chemical
weapons facilities, such as the United States. After negotiations with the OPCW technical
secretariat, Syria has agreed to comply with the methodology for destroying the above-ground
chemical weapons productions facilities in hangars, according to the Director General.87 On July
24, 2014, the OPCW Executive Council decided that 7 of the 12 hangers will be “razed to the
ground” while the remaining five hangars will be “sealed permanently to make them
inaccessible.”88 Special Coordinator Kaag said that on October 1, the OPCW would “begin
destroying the 12 remaining chemical weapons facilities—seven so-called hangars and five
tunnels.”89 This work is expected to be completed in March 2015.
Completeness of the Declaration
Another area of ongoing concern is whether or not Syria has declared all of its chemical weapons
stocks to the OPCW as required by the CWC. U.S. Ambassador Mikulak said in a July 8
statement that “Syria must respond to all outstanding questions and requests for information and

demonstrate that it has fully declared all aspects of its chemical weapons arsenal and program.”90
A White House statement on August 18 marking the end of destruction operations on the MV
Cape Ray said that “serious questions remain with respect to the omissions and discrepancies in
Syria’s declaration to the OPCW and about continued allegations of use.”91 U.S. Ambassador to
the United Nations Samantha Power said on September 4 that, “The United States is concerned
about all discrepancies, also the potential that there are real omissions in the declaration.”92 On
September 4, Special Coordinator Kaag said that dialogue continues with the Syrian government
about discrepancies in the declaration. According to press reports, the OPCW-UN Joint Mission
will return to Syria in September to further verify that Syria has declared all stocks. As noted
above, chlorine is not required to be declared or destroyed under the Chemical Weapons
Convention (CWC), although its use in warfare is still prohibited under the Convention.
Funding for CW Elimination Efforts
The international community, including the United States, has contributed both technical and
financial assistance to the OPCW-U.N. Joint Mission. In-kind technical assistance to date
includes specialized packaging from the United States for transporting chemical weapons in
Syria, security-related support from Russia for Syrian ground movement of the materials, and
cargo ships and naval vessels from Denmark and Norway.93 Italy has volunteered to provide a
port for transferring the agent from the cargo ships to the Cape Ray; the United Kingdom and
Germany have provided a chemical processing facility for the destruction of some of the chemical
materials.
According to the State Department, the United States has given approximately $6 million in
financial assistance to the OPCW and U.N. joint mission through the State Department-
administered Nonproliferation and Disarmament Fund. The United States has also given
significant in-kind assistance to international inspectors. The largest contribution to the
international effort has come from the Department of Defense Cooperative Threat Reduction
(CTR) Program. On April 8, Deputy Assistant Secretary of Defense for Countering Weapons of
Mass Destruction Rebecca K.C. Hersman said that the CTR program had allocated $160 million
to support the CW elimination effort. DOD CTR also accepted $19 million in contributions from
Germany, the UK, and Canada to assist with CTR programs, including the effort in Syria. Since
the bulk of this funding was spent preparing the MV Cape Ray and equipping inspectors, the
budget request for FY2015 is less than what was spent this past year—$15.7 million for technical
expertise and resources to support the U.N.-OPCW Joint Mission in FY2015.

Armed Conflict in Syria: Overview and U.S. Response

U.S. Policy and Assistance
Debates over U.S. policy toward Syria since 2011 have repeatedly returned to the questions of
assistance for the opposition and potential U.S. military intervention, whether to protect civilians,
target terrorist groups, or punish Syrian forces suspected of involvement in chemical weapons
attacks or other attacks on opposition-held areas. The contours of these debates are shifting amid
intensifying discussion of the wisdom, scope, costs, and risks of potential participation in newly
proposed multilateral efforts to combat the Islamic State in Iraq and/or Syria. To date,
Administration officials have stated that U.S. military intervention to shape the outcome of
Syria’s civil conflict or to change the Syrian regime may not achieve U.S. objectives, and may
lead to unintended negative consequences.
In more recent comments about the threats posed by the Islamic State, U.S. officials have
announced new multifaceted and multilateral efforts to combat the organization. President Obama
said on September 10 that he “will not hesitate to take action against ISIL, in Syria, as well as
Iraq.” As of early September 2014, no significant changes in stated U.S. policy objectives toward
the broader conflict in Syria had been announced, and President Obama had revised his June 2014
request to Congress for authority and funding to establish an overt, Department of Defense-
implemented training and equipment program for vetted Syrians (see the “Administration “Train
and Equip” Proposal and Congressional Responses” section).
U.S. officials had rejected Syrian government demands for cooperation in the fight against the
Islamic State organization, saying that the United States would not “ask for permission from the
Syrian regime” in pursuit of its anti-IS objectives. On August 25, White House spokesman Josh
Earnest told reporters that, in the view of the Administration, there was not a “lesser of two evils”
between the Islamic State and the government of Bashar al Asad. Earnest said:
In the judgment of this Administration, the people of Syria should have the opportunity to
determine the future of their country; they should have the opportunity to exercise some
influence over what kind of country they want to live in. That is a basic fundamental human
right, a basic fundamental value that this administration supports. It’s why we have weighed
in heavily in support of the moderate opposition in Syria. It’s why we urged President Asad
to leave power. And it is why we do not believe that ISIL would be acting in the best interest
of the people of Syria if they were to take over leadership of that country. …We’re not
interested in trying to help the Asad regime. In fact, we have been calling for a number of
years now for the Asad regime to step down.
While condemning Asad as a thug and a murderer and aiding some of his adversaries,
Administration officials have continued to stress the need for a negotiated political solution to the
conflict in the hopes of keeping the Syrian state intact, securing its weapon stockpiles and
borders, and combating extremist groups now active there. Administration officials have cited a
number of reasons for their reluctance to undertake direct military intervention in Syria or provide
large-scale assistance to shift the balance of power there, including fears of exacerbating the
violence; inviting greater regional spillover or intervention; or opening a power vacuum that
could benefit extremists.94 Uncertain costs, military constraints, and domestic political opposition
to such involvement also have been likely factors shaping Administration considerations.

94 Other competing foreign policy priorities also have influenced the Administration’s position, such as a desire to
maintain Russian and Chinese support for international sanctions on Iran’s nuclear program and concern that sectarian

Armed Conflict in Syria: Overview and U.S. Response

Some critics of the Administration’s policy argue that many of these negative outcomes are
occurring even in the absence of U.S. intervention and suggest that the image and influence of the
United States are weakened by a refusal to intervene to protect civilians or respond to
provocations by Asad or extremist forces. Others express concern that military intervention will
exacerbate negative conditions prevailing on the ground and suggest that the United States cannot
ensure that such intervention or support provided to opposition groups will not benefit extremists.
Recent Administration statements concerning potential terrorist threats emanating from Syria
have led to a reconsideration of many of these questions by some Members of Congress and the
public. The Administration’s June 2014 request for funding and authority to arm and train vetted
Syrian opposition forces signaled that such reconsideration had taken place, and consideration of
a broader anti-Islamic State campaign appears to be driving further reconsideration.
The implementation of U.S. strategy in Syria to date has included the provision of both nonlethal
and lethal assistance to select Syrian opposition groups, a sustained international diplomatic effort
to establish a negotiated transition, and the provision of humanitarian assistance in Syria and
neighboring countries. Through 2013, these initiatives were implemented under the auspices of an
ad hoc series of assistance notifications to Congress providing for the waiver of certain
restrictions on the use of U.S. funds for assistance in Syria and the assertion of emergency
contingency authorities to reprogram and allocate funds for use in response to the crisis.
In 2014, a shift toward independently authorized and funded assistance programs appeared to be
underway when the terms of the debate began shifting in response to the Islamic State’s offensive
in Iraq. Cumulatively, congressional notifications and requests submitted to date illustrate an
evolution of U.S. involvement in the direction of seeking deeper partnership with select
opposition actors on the ground in Syria, while seeking to bolster and unify opposition figures
based outside of Syria. The stated goal of these efforts has been to place greater pressure on
President Asad and his supporters to negotiate a transition agreement that will bring conflict in
Syria to an end. If current trends continue, the focus of these efforts could increasingly include
supporting entities in Syria that can assist in multilateral counterterrorism operations or assume
control of Islamic State-held territory and resources in the wake of any coalition military
operations targeting the group.
As of September 2014, the United States had allocated more than $287 million in support of the
non-armed opposition (including the SOC and local activists), more than half of which had been
delivered as of late March.95 The delivery of some assistance to select groups resumed after
having been suspended as a result of the Islamic Front’s seizure of SOC/SMC-controlled
warehouse facilities and intra-opposition fighting in northern Syria.96 The FY2014 Consolidated
Appropriations bill (H.R. 3547, P.L. 113-76) provided new authority for the Administration to
use FY2014 and previously appropriated monies in the Economic Support Fund (ESF) account to
provide nonlethal assistance for certain purposes in Syria (see textbox).

Armed Conflict in Syria: Overview and U.S. Response


FY2014 Consolidated Appropriations Act and Nonlethal Assistance in Syria
Section 7041(i) of Division K of the FY2014 Consolidated Appropriations Act (H.R. 3547, P.L. 113-76)
significantly expands the Administration’s authority to provide nonlethal assistance in Syria for certain purposes using
the Economic Support Fund (ESF) account. Such assistance had been restricted by a series of preexisting provisions of
law (including some terrorism-related provisions) that required the President to assert emergency and contingency
authorities to provide such assistance to the Syrian opposition and communities in Syria. The new authority makes
FY2014 and prior year ESF funding available “notwithstanding any other provision of law for nonlethal assistance for
programs to address the needs of civilians affected by conflict in Syria, and for programs that seek to—
(A) establish governance in Syria that is representative, inclusive, and accountable;
(B) develop and implement political processes that are democratic, transparent, and adhere to the rule of law;
(C) further the legitimacy of the Syrian opposition through cross-border programs;
(D) develop civil society and an independent media in Syria;
(E) promote economic development in Syria;
(F) document, investigate, and prosecute human rights violations in Syria, including through transitional justice
programs and support for nongovernmental organizations; and
(G) counter extremist ideologies.”
The act requires the Secretary of State to “take all appropriate steps to ensure that mechanisms are in place for the
adequate monitoring, oversight, and control of such assistance inside Syria,” and requires the Secretary of State to
“promptly inform the appropriate congressional committees of each significant instance in which assistance provided
pursuant to the authority of this subsection has been compromised, to include the type and amount of assistance
affected, a description of the incident and parties involved, and an explanation of the Department of State’s response.”
The act further requires the Obama Administration to submit a comprehensive interagency strategy prior to using
the authority that would include a “mission statement, achievable objectives and timelines, and a description of inter-
agency and donor coordination and implementation of such strategy.” The strategy, which may be classified, must also
include “a description of oversight and vetting procedures to prevent the misuse of funds.” Al funds obligated
pursuant to the new authority are subject to established congressional notification procedures.
FY2015 Budget Request for Syria
The FY2015 basic foreign assistance request for Syria reflects the two main elements of the
Obama Administration’s policy response: (1) humanitarian assistance to meet the needs of
internally displaced Syrians and refugees in neighboring countries, and (2) political, economic,
and nonlethal military support for national and local opposition groups. Funds provided since
2011 in Syria and in neighboring countries for these combined purposes exceed $2.6 billion to
date.
Of the total $1.26 billion in FY2015 funding requested specifically for Syria in the basic foreign
operations budget request, $1.1 billion in Overseas Contingency Operations funds would support
humanitarian response needs from the Migration and Refugee Assistance (MRA-OCO) and
International Disaster Assistance (IDA-OCO) accounts. A further $155 million from the
Economic Support Fund-Overseas Contingency Operations (ESF-OCO), International Narcotics
Control and Law Enforcement-Overseas Contingency Operations (INCLE-OCO), and
Nonproliferation, Anti-terrorism, De-mining, and Related Programs (NADR) accounts would
support the Syrian opposition and transition related initiatives. Specific proposals for the use of
those funds are not yet available. The House (H.R. 5013) and Senate (S. 2499) versions of the
FY2015 Foreign Operations Appropriations bill would extend “notwithstanding” assistance
authority for FY2015 funds, contingent on an update of a strategy required under P.L. 113-76.

Proposed Expansion of Lethal and Nonlethal Assistance
Congressional Proposals
In the 113th Congress, proposals to authorize the expanded provision of nonlethal and lethal
assistance in Syria with various provisos have been introduced or considered in committees, and
would place various conditions on assistance, establish reporting requirements, grant diverse
authorities, and set different time limitations.
• On September 15, the House Rules Committee approved consideration of an
amendment introduced by Representative Howard "Buck" McKeon (hereinafter
the McKeon Amendment)97 to the proposed FY2015 continuing resolution
(H.J.Res. 124) that represents a counterproposal to the President’s revised request
for assistance authority.
• The Senate Armed Services Committee reported version of the FY2015 National
Defense Authorization Act (Section 1209 of S. 2410) would authorize the
Department of Defense, with the concurrence of the State Department, to train
and equip vetted members of select Syrian opposition forces for limited purposes
through the year 2018.
• S. 960, the Syria Transition Support Act of 2013, was approved by the Senate
Foreign Relations Committee as amended by a 15-3 vote in May 2013.
• H.R. 1327, the Free Syria Act of 2013, was introduced in March 2013.

Armed Conflict in Syria: Overview and U.S. Response

• As noted above, House and Senate Foreign Operations Appropriations bills under
consideration for FY2015 would extend FY2014 authorities to provide nonlethal
assistance in Syria for select purposes (H.R. 5013 and S. 2499).
• Section 10010 of the House-passed Defense Department appropriations bill for
FY2015 (H.R. 4870) would prohibit the use of defense funds “to transfer man-
portable air defense systems (MANPADS) to any entity in Syria.”
• Other proposals, such as H.R. 2503 and H.R. 2432, seek to prohibit any
military assistance to combatants in Syria.
Administration “Train and Equip” Proposal and Congressional Responses
President Obama’s requests to Congress for authority and resources to train and equip vetted
members of the Syrian opposition in support of U.S. efforts to combat the Islamic State
organization have reinvigorated congressional debate on the subject. For a comparison and
analysis of specific provisions of the request and congressional proposals see CRS Report
R43727, Proposed Train and Equip Authorities for Syria: In Brief, by Christopher M. Blanchard
and Amy Belasco.
The Administration’s June 2014 request for FY2015 Overseas Contingency Operations (OCO)
funds included a request for funds and authorities for a proposed $1.5 billion Syria Regional
Stabilization Initiative (RSI), $500 million of which would support an overt training and
equipment program for select Syrians.98 In September, the President revised that request and
sought authorization from Congress to “to provide assistance, including the provision of defense
articles and defense services, to appropriately vetted elements of the Syrian opposition and other
appropriately vetted Syrian groups or individuals” for the following purposes:
(1) Defending the Syrian people from attacks by the Islamic State of Iraq and the Levant and
the Syrian regime, facilitating the provision of essential services, and stabilizing territory
controlled by the opposition;
(2) Protecting the United States, its friends and allies, and the Syrian people from the threats
posed by terrorists in Syria;
(3) Promoting the conditions for a negotiated settlement to end the conflict in Syria
As of early September, congressional consideration of this request had merged with congressional
consideration of a proposed continuing resolution to fund government operations after September
30, 2014 (H.J.Res. 124). The McKeon Amendment to H.J.Res. 124 represents a counterproposal
to the President's revised request for assistance authority. The two versions differ in significant
ways. For analysis of these differences and other congressional proposals see CRS Report

and Amy Belasco.

Armed Conflict in Syria: Overview and U.S. Response

If the President’s request were approved by Congress as requested, the use of the train and equip
authority would be not be limited by a spending cap. On September 16, Secretary of Defense
Hagel provided an updated summary of the Administration’s proposal, saying
The $500 million request the president made in June for this train-and-equip program reflects
CENTCOM's estimate of the cost to train, equip and resupply more than 5,000 opposition
forces over one year. The package of assistance that we initially provide would consist of
small arms, vehicles and basic equipment like communications as well as tactical and
strategic training. As these forces prove their effectiveness on the battlefield, we would be
prepared to provide increasingly sophisticated types of assistance to the most trusted
commanders and capable forces.99
Additional funding would be required to sustain or expand the program. As requested, the
authority would allow the U.S. government to accept foreign contributions to authorized efforts to
provide such assistance.
The Administration’s June 2014 request also sought funding and authority for expanded efforts to
“build the capacity of the Syrian opposition and of neighboring countries including Jordan,
Lebanon, Turkey, and Iraq to manage the growing spillover effects of the Syrian conflict.”
According to the June request, the Administration intends to use any funds provided by Congress
for the RSI to “leverage existing security cooperation and assistance programs, expand training
and related infrastructure, and tailor support packages to meet identified regional needs for areas
contending with refugees and other destabilizing effects from the Syrian conflict.”
Following consideration of the FY2015 continuing resolution, Members of Congress also may
return to consideration of other congressional proposals that would provide expanded authority or
funding for enhanced U.S. support to the Syrian opposition.
• As noted above, the Senate Armed Services Committee reported version of the
FY2015 National Defense Authorization Act (Section 1209 of S. 2410) also
would authorize the Department of Defense, with the concurrence of the State
Department, to train and equip vetted members of select Syrian opposition forces
for limited purposes through the year 2018.
• Section 9015 of the Senate Appropriation Committee’s version of the FY2015
Defense Appropriations bill (H.R. 4870) would authorize assistance, including
the provision of defense articles and defense services, to appropriately vetted
elements of the Syrian opposition, for, among other purposes, “protecting the
United States, its friends and allies, and the Syrian people from threats posed by
terrorists in Syria.” Under this section, the committee specifies that up to $500
million from the Defense Department’s Operation and Maintenance (O&M), a
Defense-wide account, may be used for a support program. The Senate
Appropriations Defense subcommittee considered and rejected a proposed
amendment that would have stripped the authority and funding for the Syria
program from the bill.
In addition, the Senate Appropriation Committee’s version of H.R. 4870 includes O&M
appropriations that may be used to “reimburse the government of Jordan, in such amounts as the
Secretary of Defense may determine, to maintain the ability of the Jordanian armed forces to

maintain security along the border between Jordan and Syria.” Finally, the Senate Appropriations
Committee’s version of H.R. 4870 includes $1 billion in OCO funding for the Department of
State’s Complex Crises Fund (CCF) that may be made available for the purposes of “undertaking
counterterrorism partnership efforts, responding to crises, and addressing regional instability
resulting from the conflict in Syria.”
Potential Operations against the Islamic State and Issues Shaping
Future U.S. Policy toward Syria

President Obama has stated that the United States seeks to “degrade and ultimately destroy” the
Islamic State.100 U.S. counterterrorism, defense, and diplomatic officials have referred to several
elements of an Administration strategy to achieve those objectives in public remarks. In general
terms, the Administration seeks to leverage the combined, but as yet fully defined efforts of a
multilateral global coalition to use diplomatic, military, intelligence, and law enforcement
mechanisms to “defeat” the Islamic State. It remains to be seen whether the President will take
military action against IS targets inside Syria. For discussion of related war powers and
authorities questions related to potential military action, see CRS Report IN10147,
Considerations for Possible Authorization for Use of Military Force Against the Islamic State, by
Matthew C. Weed, and CRS Report R43720, U.S. Military Action Against the Islamic State:
Answers to Frequently Asked Legal Questions
, by Michael John Garcia and Jennifer K. Elsea.
On September 5, President Obama and Secretary of State Kerry suggested that local and regional
actors would be expected to continue to bear the burden of conducting ground combat operations
with the potential future backing of such a coalition, whose members may provide training,
equipment, advice, assistance, and/or conduct supportive military operations.101 President Obama
said,
With respect to the situation on the ground in Syria, we will not be placing U.S. ground
troops to try to control the areas that are part of the conflict inside of Syria. I don’t think
that’s necessary for us to accomplish our goal. We are going to have to find effective
partners on the ground to push back against ISIL. And the moderate coalition there is one
that we can work with. We have experience working with many of them. They have been, to
some degree, outgunned and outmanned, and that’s why it’s important for us to work with
our friends and allies to support them more effectively.102
As noted above, in his address to the nation on September 10, President Obama reiterated his
request to Congress for “additional authorities and resources to equip these [vetted Syrian
opposition] fighters.”
To date, Iraqi security forces, Syrian and Iraqi Kurdish militias, Iraqi Shiite militias, Syrian
government forces, and a broad range of Syrian opposition militias remain the principal military
forces engaged in active ground combat against the forces of the Islamic State. It remains to be
determined what types of support these entities may be eligible to receive from an emergent anti-
Islamic State coalition and on what terms.

Armed Conflict in Syria: Overview and U.S. Response

Advocates of continued U.S. support for select opposition groups in Syria have argued that the
withdrawal or reduction of such assistance would bolster less cooperative or friendly groups.
Advocates have further argued that if the United States withdraws or reduces its support, then it
may “force” moderate groups to turn to extremist groups for funding and support—thereby
increasing the influence of extremists while reducing U.S. leverage.
Critics of continued or expanded U.S. support have argued that such assistance risks exacerbating
rivalry among opposition groups and reducing the credibility of groups and individuals seen to be
aligned with the United States. Critics of support proposals also have pointed to problems in
ensuring the identity and intentions of end users of provided support and the uses of U.S.-
provided materiel.
The purposes of any expanded U.S. or coalition assistance to armed opposition groups also may
be controversial among Syrians. President Obama has suggested that U.S. engagement will
remain focused “narrowly” on assisting Syrians in combatting the Islamic State, while continuing
“to look for opportunities” to support a political resolution to Syria’s conflict.103 Some Syrian
political and military opposition forces may resent such a narrow focus and insist on broader
support for their anti-Asad goals as a condition of working with a U.S.-backed coalition against
the Islamic State.
Significant political and strategic questions may be raised by proposals that would further benefit
certain non-state actors relative to national governments (such as Kurdish groups) or that might
unpredictably alter prevailing dynamics among adversaries in Syria. As noted above, the prospect
of potential international cooperation or coordination with the Asad government has already
become controversial. The timing and duration of any anti-Islamic State military operations may
also be influenced by calculations of the likely relative benefit of such operations for opposition
and government forces in Syria. Operations that seriously degrade Islamic State capabilities prior
to improvements in the organization and capabilities of U.S.-preferred armed groups could result
in substantial military gains for pro-Asad forces or other extremist groups, particularly Jabhat al
Nusra. U.S. officials have not publicly estimated how long it may take to train and equip Syrian
partner forces.
From a practical perspective, as with humanitarian assistance, U.S. efforts to directly support
security and service delivery efforts inside Syria to date have been hindered by a lack of regular
access to areas in need. According to Administration officials, border closures, ongoing fighting,
and risks from extremist groups have presented unique challenges. The infighting among
opposition forces and the empowerment of the Islamic State in eastern Syria and north and
western Iraq creates further complications. Presumably, similar access issues could hinder efforts
to expand support to forces fighting the Islamic State.
The provision of overt military assistance to anti-Islamic State or anti-Asad forces would
represent a significant evolution in U.S. efforts to support armed opposition elements. President
Obama said on September 6, that “in terms of controlling territory, we're going to have to develop
a moderate Sunni opposition that can control territory and that we can work with.”104 To date,

103 The President said, “our attitude towards Asad continues to be that you know, through his actions, through using
chemical weapons on his own people, dropping barrel bombs that killed innocent children that he—he has foregone
legitimacy. But when it comes to our policy and the coalition that we're putting together, our focus specifically is on
ISIL. It’s narrowly on ISIL.” President Obama interview with NBC News Meet the Press, September 6, 2014.

Armed Conflict in Syria: Overview and U.S. Response

U.S. officials have not publicly described which elements of the Syrian opposition may already
have received U.S. training, what any training may have entailed, what types of weaponry may
have been provided, or what safeguards may be in place to monitor the disposition of equipment
and the actions of any U.S.-trained personnel.105
Overt U.S. assistance to opposition military forces has remained restricted to nonlethal items. In
late September 2013, the Administration notified Congress of its intent to use emergency
authorities available to the President under the Foreign Assistance Act to provide additional
“nonlethal commodities and services” to the SMC. On October 22, 2013, Secretary Kerry said
that the “London 11” group had “agreed to direct military aid exclusively through the Supreme
Military Council ... to curtail the influence of extremists, to isolate the extremists, and to change
the balance on the ground.”106 In January 2014, the State Department referred to completed
deliveries of food, medical equipment, and vehicles and “planned deliveries of satellite access
equipment, laptops, radio communication equipment, and medical kits to moderate SMC
elements” in a summary of its nonlethal support efforts to date.107
As discussed above, several prominent Islamist militia groups continue to coordinate their
operations independently and have rejected the political and military leadership of the SOC/SMC.
Other non-Islamist groups also are acting independently to consolidate their operations, and
emergent coalitions seek to unite some Islamist and non-Islamist armed groups. Disputes among
former SMC commanders over leadership also may complicate international efforts to engage
with the SMC as a conduit for support to moderate armed elements, whether to increase pressure
on President Asad or to combat the Islamic State and other extremist groups. It remains to be seen
whether these realignments, disputes, and policy statements have decisively changed the context
in which the United States and its allies are providing support to the armed opposition, or whether
or how such support may change in the near future. In recent months, Administration officials,
including President Obama, have referred to the disorganization of the armed opposition as a
liability, while describing U.S. plans to increase support to select opposition elements in pursuit
of U.S. objectives.
Possible Questions for Congressional Oversight
• What international and domestic authority might the Administration seek or
assert in order to carry out military operations against the Islamic State or other
extremist groups in Syria? How much might such operations cost? How long
might they last? What geographic, durational, financial, or tactical guidance or
restrictions might Congress wish to enact, if any?

105 In June 2013, Deputy National Security Adviser for Strategic Communications Ben Rhodes said that the President
had “authorized the expansion of our assistance to the Supreme Military Council,” and Secretary of Defense Chuck
Hagel said in a September 2013 hearing before the Senate Foreign Relations Committee that the Administration was
taking steps to provide arms to some Syrian rebels under covert action authorities. Secretary Hagel said, “it was June of
this year that the president made the decision to support lethal assistance to the opposition. As you all know, we have
been very supportive with hundreds of millions of dollars of nonlethal assistance. The vetting process that Secretary
Kerry noted has been significant, but—I'll ask General Dempsey if he wants to add anything—but we, the Department
of Defense, have not been directly involved in this. This is, as you know, a covert action. And, as Secretary Kerry
noted, probably to [go] into much more detail would—would require a closed or classified hearing.”

Armed Conflict in Syria: Overview and U.S. Response

• What metrics might be used to gauge the relative success of operations against
the Islamic State? How should parallel U.S. concerns about Syria’s broader
stability and the future of its democratic opposition shape any U.S. or coalition
operations against the Islamic State in Syria?
• How might Islamic State forces respond to expanded U.S. or coalition military
operations against them in Syria? How likely are Islamic State operatives to
target countries contributing or hosting military forces? In the short term, what
forces in Syria would benefit from efforts to degrade Islamic State capabilities?
• What effects might the provision of overt military assistance to non-state armed
groups and individual combatants in Syria’s non-international armed conflict
have on U.S. efforts to discourage other actors from providing military assistance
to the Syrian government or providing similar assistance to actors in other
conflicts? What precedents, if any, would Congress be setting if it authorized and
funded such an overt program under current circumstances?
• To which groups, entities, and individuals does the Administration intend to
provide expanded assistance, including defense articles and services? For what
specific purposes? What are their political goals for the future of Syria? What
types of weaponry or training may be provided to recipients? What may not be
provided? Why? How soon could a force that meets U.S. objectives be created?
• What mechanisms will be put in place to monitor the disposition of any provided
U.S. defense articles? What specific vetting criteria will be used to assess the
worthiness of intended recipients? What conditions or criteria might prevent a
group or individual from being eligible for U.S. assistance?
• Where will such training and equipping efforts take place? With what
implications for the host country or countries? How does the Administration
expect the current Syrian government and its allies to respond to those assisting
any such U.S. efforts?
• How might the provision of overt military assistance to the Syrian opposition or
the conduct of military operations in Syria against Islamic State targets without
Syrian government permission or cooperation affect the willingness of the Asad
government to cooperate on issues of importance to the United States, including
counterterrorism, regional security, and the conflict in Iraq? How might the
provision of U.S. military assistance to select groups affect the balance of power
and political relations among different Syrian opposition groups?
• What countries are likely to contribute financially or militarily to potential U.S.
or coalition efforts against the Islamic State in Syria? How might the United
States respond if other governments pursue anti-Islamic State or anti-Asad
operations outside the framework of a U.S.-led coalition? Will the United States
welcome the support of Iran or Hezbollah for anti-Islamic State operations in
Syria?
• On what basis and terms should the Administration report to Congress on the
status, achievements, and outstanding goals of anti-Islamic State operations in
Syria? What additional administrative, program management, and oversight
costs, if any, might be associated with proposals to expand support for armed
groups in Syria in relation to new anti-Islamic State goals?

Armed Conflict in Syria: Overview and U.S. Response

Outlook
Looking ahead, U.S. policy makers face a series of difficult choices as they maintain their
demands that Asad ultimately leave power; express their desire for the Syrian government to
remain cooperative with implementation of its chemical weapons-related commitments,
participate in negotiations with the opposition, and facilitate humanitarian access; and pursue new
initiatives to degrade and defeat the Islamic State. By seeking a negotiated rather than a military
solution to the conflict in Syria, U.S. policy makers have sought to bring the conflict to a close
while maintaining the security benefits associated with the preservation of some Syrian state
institutions. Those security concerns appear to be reflected in President Obama’s recent
statements suggesting expanded U.S. engagement in Syria would remain “narrowly” focused on
the Islamic State. Nevertheless, as recently as April, Secretary of State John Kerry alluded to a
need to make the Asad government feel less secure and to expand support to the opposition in
order to bolster chances for successful negotiations. It could prove difficult to manage those
efforts while taking new action against Islamic State operatives and other extremists in Syria.
The McKeon Amendment to H.J.Res. 124 would authorize assistance to vetted Syrians to protect
Syrians from attacks by the Islamic State, whereas the Administration originally sought
authorization to provide assistance that would help defend Syrians from Asad regime attacks.
Neither proposal defines “promoting conditions for a negotiated settlement to end the conflict in
Syria,” which both refer to as a purpose of U.S. assistance. In broad terms, the Administration
argues that pressure must be brought to bear on the government of Bashar al Asad in order to
convince its leaders to negotiate a settlement to the conflict that would result in their departure
from office. Administration officials have not publicly described the precise nature of such
intended pressure, the specific terms of its application, or potential measures of its success in
achieving its related strategic ends. On September 16, General Martin Dempsey referred to an
“ISIL first strategy” in response to a question on U.S. priorities during a Senate Armed Services
Committee hearing. Neither proposal explicitly states that the departure of Bashar al Asad or
members of his government is an essential condition for a negotiated settlement.
Absent a change in conditions that compels Asad’s departure or empowers opposition groups to
fully depose Asad, current U.S. demands for a negotiated settlement leading to the establishment
of a transitional governing body would appear to require the leaders of the current government to
agree to leave power voluntarily, which they may continue to resist doing without guarantees of
their safety and/or immunity. Opposition members may be unable or unwilling to make such
guarantees. U.S. officials have raised the prospect of international peacekeeping arrangements to
guarantee elements of a negotiated settlement, but such arrangements could require an
international mandate, military forces, and financial contributions that may prove difficult to
procure. Meanwhile, powerful armed Islamist opposition forces reject negotiation, seek the
creation of an Islamic state, and have vowed to continue fighting until the entire Syrian
government is toppled.
Reconciling the current U.S. diplomatic strategy and desire for cooperation on chemical weapons
facility destruction with the simultaneous provision of U.S. assistance to select elements of the
opposition may become more difficult in the event that negotiations begin and show promise, or
in the event that anti-U.S. Islamist forces or Al Qaeda affiliates make further gains at the expense
of their counterparts. In light of these conditions, responding to the humanitarian needs generated
by the crisis and working to prevent the further destabilization of Syria’s neighbors will remain
key agenda items for U.S. decision makers for the foreseeable future.
