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

Summary
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. Since March
2011, the conflict has driven more than 2.8 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 billion in funding identified to date. The United States also has
allocated a total of $287 million to date to provide nonlethal assistance to select groups.
Neither pro-Asad forces nor their opponents appear capable of achieving outright victory in the
short term. Improved coordination among some anti-government forces and attrition in
government ranks make a swift reassertion of state control over all of Syria unlikely. Conflict
between the Islamic State of Iraq and the Levant (ISIL, a.k.a. ISIS) and other anti-Asad forces has
intensified. The war in Syria is exacerbating local sectarian and political conflicts within Lebanon
and Iraq, threatening national stability.
In spite of an apparent shared antipathy toward ISIL’s brutality among opposition groups, many
anti-Asad armed forces and their activist counterparts remain divided over tactics, strategy, and
their long-term political goals for Syria. At present, 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 impose varying degrees of Sunni Islamic law
on Syrian society, including members of the Islamic Front, ISIL, and Jabhat al Nusra, have
marginalized others who had received U.S. assistance.
The United States and other members of the United Nations Security Council seek continued
Syrian government cooperation with efforts to verifiably end Syria’s chemical weapons program
and provide relief. As of June 23, 2014, all of Syria’s declared chemical weapons had been
removed from the country. The Security Council also has endorsed principles for a negotiated
settlement of the conflict that could leave members of the current Syrian government in power as
members of a transitional governing body, an outcome that some opposition groups reject. The
FY2014 Consolidated Appropriations Act (H.R. 3547, P.L. 113-76) authorizes the Administration
to provide nonlethal assistance in Syria for certain purposes notwithstanding other provisions of
law that had restricted such assistance previously. The Administration is seeking $1.25 billion in
State Department funding for the Syria crisis in FY2015, including $1.1 billion for humanitarian
programs. The Senate version of the FY2015 defense authorization bill (Section 1209 of S. 2410)
would authorize the arming and training of vetted opposition forces for select purposes.
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 contain or fully address. Large numbers
of Syrian refugees, the growth of powerful armed extremist groups in Syria, and the assertive
involvement of Iran, Turkey, and Sunni Arab governments in Syria’s civil war are all negatively
affecting the regional security environment in the Middle East. In light of these conditions and
trends, Congress is likely to face choices about the investment of U.S. relief and security
assistance funding in relation to the crisis in Syria and its effects on the region for years to come.

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 and have advanced in key areas in recent months. The
Asad government continues to receive support from Russia and Iran, and, contrary to some
observers’ predictions, has shown no indication of an imminent collapse. 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 areas of northeastern Syria and may seek autonomy or independence in the future.
Meanwhile, chemical weapons inspectors work to oversee and implement the terms of the
September 2013 chemical disarmament agreement endorsed by the United Nations (U.N.)
Security Council in Resolution 2118. Some rebel groups and regional governments have
criticized the U.S. decision to forego a threatened military strike against Syrian government
forces in response to the Syrian military’s alleged use of chemical weapons in August. Members
of Congress expressed a broad range of views regarding the potential use of force in Syria during
intense debate in September, and Obama Administration officials have stated that they believe
that the threat of the use of force by the United States was instrumental in convincing Syrian
President Bashar al Asad to commit to the disarmament plan. Recent allegations of the use of
chlorine gas by government forces have revived debates about appropriate responses.
With internationally supervised disarmament proceeding, U.S. diplomatic efforts remain
committed to shaping the terms and conditions for negotiation to end the fighting and establish a
transitional governing body as called for by a communiqué agreed to in Geneva in June 2012.
That communiqué was further endorsed in Resolutions 2118 and 2139, and served as the basis for
the January-February 2014 “Geneva II” talks in Switzerland involving some members of the
Syrian opposition, representatives of the Syrian government, and delegates from dozens of
countries. Those talks failed to address the establishment of a transitional body, based largely on
Syrian government insistence that terrorism concerns be resolved first.
Several unarmed and armed groups rejected the Geneva II talks outright, and opposition forces
remain divided over questions of whether and under what conditions to participate in negotiations
with the Asad government. Advances by pro-Asad forces and opposition forces in the subsequent
months have led some supporters of each side to argue for continued fighting rather than
negotiation. However, neither pro-Asad forces nor their opponents appear capable of achieving
outright victory in the short term. Combat between Islamic State of Iraq and the Levant (ISIL, aka
ISIS)1 and other anti-Asad forces across northern and eastern Syria has intensified since late
December 2013, and in June 2014, ISIL launched a major offensive in north-central Iraq. ISIL’s
operations have reinvigorated U.S. debate about policy responses to conflict in both countries.

1 The Islamic State of Iraq and the Levant (ISIL) also is commonly referred to in English language reports as the
Islamic State of Iraq and Al Sham (ISIS). Al Sham is an Arabic term for the Levant. Some Syrians and others in the
region refer to ISIL as “Daesh,” the acronym for its name in Arabic Ad Dawla al Islamiyya fil Iraq wa-ash Sham.

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

In spite of an apparent shared antipathy among opposition groups toward ISIL’s brutality, many
anti-Asad armed forces and their activist counterparts remain divided over tactics, strategy, and
their long-term political goals for Syria. U.S. intelligence estimates 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.”
As of May 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), ISIL, and Jabhat al Nusra—
have marginalized other armed groups, including some that received U.S. assistance. U.S.
intelligence community leaders have identified the approximately 26,000 members of ISIL,
Jabhat al Nusra, and Ahrar al Sham (a key component of the Islamic Front) both as extremists and
as the most effective opposition forces in the field. U.S. officials believe that as many as “7,500
foreign fighters from some 50 countries” have travelled to Syria, including Al Qaeda-linked
veterans of previous conflicts and Western nationals.2
In its 2014 threat assessment testimony, the U.S. intelligence community judged that Asad
“remains unwilling to negotiate himself out of power” and “almost certainly intends to remain the
ruler of Syria.”3 Iran and Hezbollah share that objective and continue to invest heavily in Syria on
Asad’s behalf. That testimony noted that infighting among anti-Asad groups has given
government forces and their supporters an advantage in some areas, but that an overall stalemate
is likely to prevail in the conflict for the foreseeable future.4
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 2.8 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 billion
allocated to date.5 In December 2013, the U.N. Office for the Coordination of Humanitarian
Assistance (UNOCHA) appealed for an additional $6.5 billion in humanitarian assistance funding
to respond to the crisis in 2014.6 For more information on humanitarian issues, see CRS Report

contain or fully address. The region-wide flood of Syrian refugees, the growth of armed extremist
groups in Syria, and the assertive involvement of Iran, Turkey, and Sunni Arab governments in
Syria’s civil war are negatively affecting overall regional stability. The war in Syria also is
exacerbating local sectarian and political conflicts within Lebanon and Iraq, where violence is
escalating and threatens national stability.
Policy makers in the United States and other countries appear 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.
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 as well as to provide nonlethal and lethal support to armed groups affiliated with a
Supreme Military Command Council (SMC), whose leadership is in flux. In mid-February, SOC
figures announced that General Salim Idris was being replaced as SMC commander by Brigadier
General Abdul-Ilah al Bashir al Noemi: Idris and other commanders have rejected the change and
distanced themselves from the SMC’s new general staff and SOC defense minister. Many armed
Sunni groups disavowed the SOC’s participation in January-February 2014 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).7
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 April 2014, a coalition of militia forces
known as Harakat Hazm (Resoluteness Movement) released a video of their operatives loading
and firing what appeared to be U.S.-origin anti-tank weaponry in Syria.8 Estimates of the
coalition’s size range from the hundreds to low thousands, and its leaders have made statements
supporting secular and inclusive policy goals for a post-conflict Syria. Specific public
information is lacking about which units or personnel within the coalition may have access to
U.S.-origin weaponry, and several other armed groups have since posted social media material

7 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 May 5, 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.

purporting to demonstrate their access to the same weaponry. An official affiliated with Harakat
Hazm told the New York Times that “friendly states” had provided “modest numbers” of the
weapons.9 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.”10
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.”11 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.”12 On May 28, President Obama said, “I will work with Congress to ramp up support for
those in the Syrian opposition who offer the best alternative to terrorists and brutal dictators.”13
The Administration has endorsed a Senate Armed Services Committee proposal to authorize the
arming and training of vetted opposition forces for select purposes contained in Section 1209 of
S. 2410.
Section 3(a)(2) of the Arms Export Control Act (22 U.S.C. 2753 (a)(2)) applies obligations,
restrictions, and possible penalties for misuse of U.S.-origin equipment to any retransfer by
foreign recipients of U.S.-supplied defense articles, defense services, and related technical data to
another nation. If such a retransfer occurred in the absence of prior U.S. approval, then the nation
making such a transfer could be determined to be in violation of its agreement with the United
States not to take such an action without prior consent from the U.S. government, with possible
penalties as described in the Act.
Armed Islamist Groups
In late 2013, a number of powerful Islamist militia groups—some of which formerly recognized
the leadership of Idris and the SMC—announced the formation of a new Islamic Front.14 The
Islamic Front and other recently created opposition coalitions active in northern Syria moved to
evict ISIL from areas of northern and western Syria in January 2014 and remain engaged in
hostilities with ISIL forces in some areas. Prior to the outbreak of the confrontation with ISIL,
many expert observers considered the Front to be the most powerful element of the armed
opposition in northern Syria. The pressures of confrontation between members of the Islamic

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

Front and ISIL may be undermining the cohesion of the group, as differences in ideology,
strategy, priorities, and preferred tactics encourage individuals, units, and groups within the Front
to reconsider their positions.
The 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.”15 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.16 The statement calls
for “the entire regime, including its head and all its criminal figures” to step down and calls for
security bodies to be held legally accountable. The Front and its allies further demand 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 ISIL and its adversaries, but is now in outright
conflict with ISIL (see Figure 2 for a timeline of the emergence of the groups). Their
confrontation is sending shockwaves through the global jihadist community as different clerics,
armed group leaders, and individual supporters declare their respective views on the infighting. In
general, other Syrian opposition forces have viewed Al Nusra as more accommodating and
cooperative than ISIL, including some groups who oppose Al Nusra’s ideology. Some members
of the Islamic Front and other non-Islamist opposition groups coordinate their operations with
Jabhat al Nusra in different areas. The pressures of combat against ISIL 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.”17 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 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 continued 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 with the Front and its allies.
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”)18 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.... ”19 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 Al
Qaeda-affiliated groups in Syria or against pro-Asad forces.
Terrorist 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 a direct terrorist threat to the United States. U.S. and European
officials have highlighted the particular threat 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.20
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 press reports, unnamed
intelligence officials have described the foreign fighter problem as “one of the most significant
threats we’re dealing with,” and the Federal Bureau of Investigation reportedly is monitoring
several returnees from Syria. Homeland Security Secretary Jeh Johnson has called the terrorist
threat from Syria “a matter of homeland security.”

18 The group consists of Egypt, France, Germany, Italy, Jordan, Qatar, Saudi Arabia, Turkey, the United Arab Emirates,
the United Kingdom, and the United States.

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

Islamic State of Iraq and the Levant (ISIL, a.k.a. ISIS)
The Islamic State of Iraq and the Levant (ISIL, also referred to as ISIS) 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. The group’s ideological and organizational
roots 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),21 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, ISIL leaders have stated their view that “the ISIL
is not and has never been an offshoot of Al Qaeda,”22 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 Nusra Front, under the name ISIL. Nusra Front 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 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 ISIL threat. Inside Syria, ISIL alienated its
rebel counterparts further, and an anti-ISIL campaign erupted there in early 2014, expelling the
group from some areas it had controlled and unleashing a cycle of ongoing infighting. ISIL
remains strongest in Raqqah and Syria’s eastern provinces of Dayr az Zawr and Hasakah,
adjacent to western Iraq. ISIL’s attempts to assert control over the cities of Fallujah and Ramadi
in Iraq’s Al Anbar province and its June 2014 offensive in northern Iraq underscored the group’s
lethality and ability to conduct combat operations and manage partnerships with local groups in
multiple areas over large geographic distances. The durability of ISIL’s partnerships is
questionable given its conflicts in Syria and past opposition from tribal, Islamist, and Baathist
armed groups in Iraq.

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

and unsupportive Sunnis as enemies in the group’s struggle to establish “the Islamic State” and to
revive their vision of “the caliphate.”23 The group describes Iraqi Shiites derogatorily as
“rejectionists” and “polytheists” and paints the Iraqi government of Nuri al Maliki as a puppet of
Iran. Similar ire is aimed at Syrian Alawites and the Asad government, although some sources
allege that ISIL operatives have benefitted from evolving financial and security arrangements
with Damascus dating back to the time of the U.S. presence in Iraq.
Deputy Assistant Secretary of State for Iraq Brett McGurk told the House Foreign Affairs
Committee in February 2014 that ISIL’s objective is “to cause the collapse of the Iraqi state and
carve out a zone of governing control in the western regions of Iraq and eastern Syria.” ISIL has
since built upon what McGurk described then as its “unprecedented” resources in terms of funds,
weapons, and personnel. Several leading representatives of the U.S. intelligence community have
stated that ISIL maintains training camps in Iraq and Syria, has the intent to attack the United
States, and is reportedly recruiting and training individuals to do so. 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.”24 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.”25
Potential Effects of ISIL Operations in Iraq on Syria26
ISIL gains in Iraq are likely to facilitate the flow of weapons and fighters into eastern Syria to
ISIL and other groups, and may increase bilateral cooperation between the Maliki and Asad
governments. Captured U.S.-origin military equipment provided to Iraqi security forces already
has appeared in photos reportedly taken in Syria and posted on social media outlets. ISIL
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 ISIL.27 Syrian forces in mid-June conducted air strikes against ISIL-held areas of Raqqah
and Hasakah in coordination with the Iraqi government, according to the London-based Syrian
Observatory for Human Rights.28 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 ISIL gains in Iraq would have outside of eastern Syria. At least half of
Syria-based ISIL fighters are Syrian or Iraqi tribesmen, according to a Syrian ISIL defector.29
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, ISIL 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
ISIL supply lines linking eastern Syria and western Iraq could benefit Syrian military and Al
Qaeda-affiliated Nusra Front forces also operating in the area.
Pro-Asad Forces30
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 in Aleppo and Damascus in an effort to isolate rebels
and sever their supply lines.31 The government since the beginning of the year has also conducted
more than 40 local truces with rebel groups in besieged areas of Damascus, Damascus
Countryside, and Homs that have allowed it to gain greater control in some contested areas.32
Syria in early June held presidential elections—the first since 1955 in which there has been more
than one candidate.33 Elections were held in all provinces except Raqqah in northern Syria, which
remains under the control of ISIL.34 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—giving him a third seven-year term in office.35 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.36 Syria’s Supreme Constitutional court put voter turnout
at 73.4%, although some Asad opponents stated that they voted primarily to avoid retribution.37
Syrian oppositionists, as well as the United States and the European Union, condemned the vote
as illegitimate.38
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

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

Communique’s call for the establishment of a transitional governing body. 39 Although the Syrian
government participated in the Geneva II negotiations, 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, and that peace talks will further
expose opposition divisions—perhaps thereby demonstrating that his government lacks a credible
negotiating partner.
The Geneva II Talks
The January-February 2014 Geneva II talks brought many of the internal and external fault lines in the conflict into
sharp relief. Divergent perspectives among Syrian parties to the conflict were reflected among their respective
international backers. The negotiations failed to make progress toward the establishment of a transitional governing
body (TGB), but provided an opportunity for some members of the U.S.-recognized National Coalition of Syrian
Revolution and Opposition Forces (or Syrian Opposition Coalition, SOC) to demonstrate their capability to
represent the interests of Syrians and potential y improve their standing with some of the disparate opposition forces
engaged in fighting inside Syria. Nevertheless, other opposition groups, including several powerful Islamist militias,
rejected the negotiations and stated their intention to keep fighting until their demands are met.
According to U.N. officials, the Syrian government delegation refused to engage in discussions aimed at establishing a
TGB and sought to focus on the question of combatting terrorism. Syrian military operations, including attacks on
rebel held areas of Aleppo using barrel bombs and other indiscriminate means, continued during the talks and killed
hundreds of civilians. Prior to the talks, President Asad stated that the government had already laid out its peace
initiative in January 2013.40 Under the first stage of this plan, the Syrian armed forces would halt military operations as
soon as regional countries stopped funding and arming the opposition and when the opposition itself ceased attacks.41
The United States and other members of the Core Group have reiterated their support for negotiations on the terms
of the Geneva communiqué, while criticizing the Asad government for “obstruction” and praising the SOC delegation
for its participation in the talks.42 Syrian government representatives criticized what they viewed as the opposition
delegation’s unwillingness to fully discuss terrorism and its inability to make firm commitments on the actions of
armed groups.43 The Asad government appears unwilling to open discussions regarding any transitional arrangements
until its concerns with regard to terrorism and anti-state violence are addressed. Opposition representatives
acknowledge the threats posed by extremist groups, but view the establishment of transitional arrangements as
necessary for undermining the legitimacy of violent extremist groups.
The potential for future talks is uncertain, although participants and international supporters on both sides
characterized the end of the January-February round of discussions as a recess and agreed to a four point agenda to
guide talks if they resume. The four agenda items, as described by Joint Special Representative for Syria (JSRS) Lakhdar
Brahimi, are (1) violence and terrorism; (2) the TGB; (3) national institutions; and (4) national reconciliation and
debate.44 Obama Administration officials have reiterated their shared view that once a Transitional Governing Body
[TGB] cal ed for by the Geneva communiqué is established by mutual consent and has full control over state security
services, “Asad and his close associates with blood on their hands will have no role in Syria.” United Nations Security
Council Resolution 2139 reiterated the Council’s endorsement of the Geneva communiqué and demanded that
parties support its implementation “leading to a transition that meets the legitimate aspirations of the Syrian people
and enables them independently and democratically to determine their own future.”

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

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 now 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.45
Hezbollah
In August 2012, the U.S. Treasury Department sanctioned Hezbollah for providing training,
advice, and logistical support to the Syrian government.46 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.47 He further referred to
the need for reconciliation initiatives to bolster the Asad government’s support among Syrians.
As of June 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.48 A senior Israeli military official in March 2014 stated that
Hezbollah currently maintains 4,000 to 5,000 fighters in Syria.49
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.50
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.51 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

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

Hezbollah-controlled areas of Beirut and eastern Lebanon, describing the attacks as retaliation for
Hezbollah’s intervention in Syria.52
Iraqi Militias
Analysts estimate that there are between 2,000 and 5,000 Iraqi Shia fighting in Syria on behalf of
the Syrian government.53 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.54
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.55
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.56 Recent gains by ISIL in Iraq have prompted some Iraqi fighters in
Syria to return home and join local militias.57
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.58 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,59 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.60 In terms of non-lethal aid, Iran

has provided Syria with billions of dollars in credit to purchase oil, food, and import goods from
Iran.61
Chemical Weapons and Disarmament: Background62
A major policy concern of the United States has been the use or loss of control of chemical
weapons stocks in Syria during that country’s 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. The largest-scale use to date was reportedly
on August 21, 2013. 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. Reports of attacks using
chlorine gas in Hama province surfaced in mid-April 2014. The U.N. Fact-Finding Mission to
investigate the allegations came under armed attack during an attempt to examine the site on May
27. The investigators concluded that the evidence they have been able to examine thus far “lends
credence to the view that toxic chemicals, most likely pulmonary irritating agents such as
chlorine, have been used in a systematic manner in a number of attacks.”63
In August 2013, the Obama Administration threatened military action against Syria in response to
chemical weapons use in Syria. In a diplomatic solution that resulted in the Administration
withdrawing the threat, Syria agreed to join the international Chemical Weapons Convention
(CWC), which requires Syria to destroy all of its chemical weapons stocks and production
facilities and bans the use of any toxic chemicals in warfare. Based on a joint U.S.-Russian
proposal, the Executive Council of the OPCW,64 an intergovernmental body tasked with
implementation of the CWC, approved a destruction plan under which Syria is required to destroy
all chemical weapons by June 30, 2014. According to the Director General, Syria will not meet
the June 30 deadline for destruction of all chemical weapons and production facilities,65 but all
declared chemical weapons agents have been removed from the country as of June 23, 2014.
Syria is required to declare and destroy all of its chemical weapons stocks and production
facilities under international supervision. 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.66

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

A joint mission of U.N. and OPCW personnel was created to monitor and facilitate Syrian
chemical weapons disarmament.67 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 that the Syrian government met the
November 1, 2013, destruction deadline for disabling production equipment, and that all chemical
weapons stocks and agents in Syria were under “tamper-proof” seal.
Removal of Chemicals
The second stage of the chemical weapons destruction process involved transportation and
removal of chemical weapons agents from the country. These are 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 have 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 is the first time all of a country’s declared chemical weapons agents
have been removed from its territory.
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 is expected to receive 700 metric tons of both
mustard agent and DF compound, a key component in sarin.68 U.S. personnel, including 64 Army
chemical specialists, will run the operation. Once removed from Latakia, the most dangerous
compounds in approximately 60 containers will be transferred to the Cape Ray at the Italian port
of Gioia Tauro for destruction at sea in international waters. NATO has canceled cooperation with
the Russian Federation on guarding the Cape Ray during chemical weapons destruction activities
because of Russia’s actions in Ukraine.69 Less sensitive chemicals will be shipped to commercial
processing facilities, for example in the United Kingdom. Companies in Finland and the United
States were awarded contracts for processing the liquid waste from the destruction process.70
Syria did not meet the original deadline of December 31, 2013, for removal of these agents from
its territory. 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.”71 Reports in early January quoted a
Syrian government official as saying two CW storage sites have been under attack.72 The Syrian
government also missed a February 5, 2014, deadline, raising 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.73
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.”74 As of 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).75 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.76 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.77
Destruction of Production Facilities
The Syrian government also did not meet the deadline of March 15, 2014, for destruction of its 12
chemical weapons production facilities, and has proposed that the facilities not be completely
destroyed but instead made inaccessible.78 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.79 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,” and Syria was not cooperating
with the Technical Secretariat to resolve the issue. 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. As of June 17, 2014, Syria has agreed to comply with the methodology for
destroying the above-ground chemical weapons productions facilities in hangars, according to the
Director General. There has been no resolution on destruction of the underground structures.80
U.S. and International Funding for CW Elimination Efforts
The international community, including the United States, is contributing 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.81 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 question of
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. 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. Administration officials have cited a number
of reasons for their reluctance to undertake direct military intervention or provide large-scale
assistance to shift the balance of power in Syria, including fears of exacerbating the violence;
inviting greater regional spillover or intervention; or opening a power vacuum that could benefit
the extremists who are part of the opposition.82 Uncertain costs, military constraints, and domestic
political opposition to such involvement also are likely factors.
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. Others express concern that military intervention will exacerbate negative
conditions prevailing on the ground and suggest that the United States cannot ensure that
intervention or support provided to opposition groups will not benefit extremists.
Recent Administration official 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. Some press reports suggest that Administration officials may be revisiting policy
options that could expand U.S. involvement in the conflict in Syria, but U.S. officials have
declined to confirm or deny reports about the contours of internal deliberations. On April 8,
Secretary of State Kerry referred to ongoing consideration of policy options in testimony before
the Senate Foreign Relations Committee and suggested that the United States was more engaged
in supporting opposition elements than it had been to date. Subsequent press reports concerning
armed opposition forces using limited quantities of U.S.-origin advanced weaponry in Syria lead
many observers to assume that some incremental changes in U.S. policy are occurring. However,
Administration officials maintain that U.S. policy goals and the contours of the United States’
declared policy goals and preferred means have not fundamentally changed.
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. 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

82 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
and strategic competition in Syria could ignite a regional conflict and threaten U.S. allies and global security interests.

allocate funds for use in response to the crisis. Cumulatively, the notifications 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.
At the October 2013 Friends of Syria conference in London, Secretary Kerry announced that the
United States, along with other members of the “London 11” group, had “agreed to increase ...
coordinated assistance to the opposition, including to the Syrian Opposition Coalition.... And we
also committed to do more to assist the brave people who are on the ground in Syria.” The
Obama Administration subsequently notified Congress of plans to expand nonlethal assistance to
various opposition groups. Through 2013, U.S. efforts to improve coordination among opposition
groups in aid delivery had mixed success, with some observers criticizing the SOC’s Assistance
Coordination Unit (ACU) for lacking capacity and duplicating partnerships.
As of June 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.83 The delivery of some assistance to select groups has been 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.84 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.
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 non-lethal 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.”

Assistant Secretary of State for Near East Affairs Anne Patterson Testimony before the Senate Foreign Relations
Committee, March 26, 2014.
84 The State Department has reported that lines of supply for nonlethal support to armed opposition elements are
“periodically contested by the regime or extremist fighters.” In the wake of the incident the Obama Administration
“decided that it was a risk to be providing that assistance if it’s going to the extremists.” See Secretary of State Kerry,

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 latter provision may be of particular interest in light of the reported seizure of U.S. provided assistance by armed
groups in December 2013.
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 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 non-
lethal military support for national and local opposition groups. Funds provided since 2011 in
Syria and in neighboring countries for these combined purposes exceed $2 billion to date.
Of the total $1.26 billion in FY2015 funding requested specifically for Syria in the 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. If a transition should occur,
FY2015 funds would support a political transition toward democracy, as well as reconstruction
and recovery efforts. Specific proposals for the use of those funds are not yet available. The
House version of the FY2015 State Department and Foreign Operations Appropriations bill
would extend “notwithstanding” assistance authority for FY2015 funds, contingent on an update
of the strategy required under P.L. 113-76.

a. The FY2013 total figure does not reflect all of the $287 million al ocated for support to the Syrian
opposition to date. The FY2015 Syria request includes, but Table 3 does not show, $1.1 billion within
Migration and Refugee Assistance (MRA-OCO) and International Disaster Assistance (IDA-OCO) accounts
expected to be used for humanitarian assistance related to the Syria conflict.
Proposed Legislation to Expand Lethal and Nonlethal Assistance
In the 113th Congress, other proposals to authorize the expanded provision of nonlethal and lethal
assistance in Syria with various provisos have been introduced or considered. 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. The Senate 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.
Issues Shaping Future U.S. Assistance
As with humanitarian assistance, U.S. efforts to support local security and service delivery efforts
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. U.S. officials have stated their expectation that U.S. equipment will
be returned to the control of SMC leaders by the Islamic Front and reiterated their view that the
SOC and SMC remain the “legitimate representatives of the Syrian opposition and the Syrian
people.”85 On January 12, the United States and other Core Group members stated that they “fully
support the Supreme Military Council of the Free Syrian Army and other democratic opposition
forces in their action against the Islamic State of Iraq and the Levant (ISIL).”
In light of these developments, the future nature and direction of U.S. engagement with certain
Syrian opposition groups may be in flux. On the one hand, advocates of continued U.S. support
for opposition groups aligned with U.S. values and preferences argue that the withdrawal or
reduction of such assistance would bolster less cooperative or friendly groups. Advocates further
argue 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. On the other hand, critics of continued U.S. support
argue 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
further point to problems in ensuring the identity of end users of provided support and the uses of
U.S.-provided support. Administration officials have stated that they remain open to engagement
with all opposition groups not affiliated with Al Qaeda. The Islamic Front reportedly has rebuffed
U.S. requests for consultation to date, and its charter states that it rejects “foreign dictates that
undermine its decision-making capabilities.”86

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

Efforts to provide lethal assistance to armed opposition elements have similarly evolved and are
reported to be expanding after sustained criticism by some opposition leaders that desired support
had not been forthcoming. 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.87 Press
reports have cited unidentified U.S. officials suggesting that as of early October 2013, very little
lethal equipment had been delivered and fewer than 1,000 opposition fighters had received U.S.
supervised training in Jordan. CRS cannot confirm these reports. Press reports further suggested
that the program was being enlarged to produce “a few hundred trained fighters each month,”88
but it is unclear what effect, if any, recent developments, including infighting among opposition
groups, have had on any such plans or programs.
To date, U.S. officials have not publicly described in detail which elements of the opposition may
be receiving training, what such training may entail, what types of weaponry may be provided in
the program, and what safeguards may be in place to monitor the disposition of equipment and
the actions of any U.S.-trained personnel. In late September, 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. In January, 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.89
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.”90 However, as
noted above, several prominent Islamist militia groups now coordinate their operations
independent of the SMC and have rejected the political and military leadership of the SOC/SMC.
Disputes among former SMC commanders over its leadership also may complicate international
efforts to engage with the SMC leadership as a conduit for support to moderate armed elements.
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. On April 8, 2014,
Secretary Kerry told the Senate Foreign Relations Committee that “the fact is we are doing more
than we've ever been doing.” As noted above, the appearance of new weaponry in the hands of
forces affiliated with SMC figures has raised speculation about changes in U.S. policy.

87 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 non-lethal
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

Outlook
Looking ahead, U.S. policy makers face a series of difficult choices as they seek to balance their
demands that Asad ultimately leave power on the one hand, and their desire for the Syrian
government to remain cooperative with implementation of the OPCW Executive Council
decision, participate in negotiations with the opposition, and facilitate humanitarian access on the
other. By seeking a negotiated rather than a military solution, U.S. policy apparently seeks to
bring the conflict to a close while maintaining the security benefits associated with the
preservation of some Syrian state institutions. However, recent statements by U.S. officials and
other members of the Core Group envision negotiations that will end with the leaders of the
current regime having no part in transitional governance in Syria.
In April, Secretary of State Kerry acknowledged that President Asad felt more confident in his
position and alluded to a need to change the calculus of the Asad government and the opposition
in order to bolster chances for successful negotiations. In testimony before the Senate Foreign
Relations Committee on April 8, Secretary Kerry said:
Today, Assad feels fairly secure in Damascus and in some of the corridor going north to the
ports. And that’s been his strategy. But around him in the south, particularly, in the east and
in the north, there is not that kind of security. In fact, the opposition has made some gains
recently. And so the key here is - how do you get the parties to a place where they both
understand that there isn't going to be a military solution that doesn't destroy the country
absolutely and totally, but which ultimately could be negotiated? There has to be a
recognition by both of the ripeness of that moment. It’s not now. We all understand that. So
the question is: Can you do something in order to create that? And that’s a legitimate
question for the Congress; a legitimate question for the Administration.
In May 2014, an unnamed senior Administration official reiterated the challenges posed to U.S.
preferences by the prevailing military asymmetry in Syria and said, “while we continue to push
for a genuine political solution, we also are focusing on doing what we can, together with the
opposition, to try to address that asymmetry in various ways, to strengthen the opposition, and
also to try to bring increased pressure of various types on the Assad regime.”91
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
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. The Obama Administration has yet to signal that ISIL’s advances in neighboring
Iraq have changed its calculus vis-à-vis the conflict in Syria.
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.
