Why it Matters
The collapse of Bashar al-Assad's regime in December 2024 fundamentally reshaped Syria-U.S. policy, forcing Washington to recalibrate its approach to a nation fractured by over a decade of conflict. A new Congressional Research Service (CRS) report examines how the Trump Administration is navigating this transition, weighing humanitarian imperatives against security concerns and geopolitical competition. How Congress and the Administration respond will shape regional stability and America's credibility as a partner.
The Big Picture
The humanitarian toll from Syria's conflict remains staggering. As of May 2026, an estimated 15.6 million Syrians were in need of humanitarian or protection assistance, with 3.6 million refugees in nearby countries and 5.9 million internally displaced. The World Bank estimated Syria's post-conflict reconstruction needed $216 billion in 2025, a figure that underscores the scale of devastation.
Yet the crisis extends beyond humanitarian need. Syria's political transition is fragile and contested: the country's transitional leaders have roots in Hayat Tahrir al-Sham, a designated terrorist organization that spearheaded the regime's overthrow. Furthermore, the current president, Ahmed al-Sharaa, has previous ties to Al-Qaeda. Senior UN officials, as of May 2026, described humanitarian gains as "real but fragile," while noting that "responsive governance remains a work in progress." The administration of President al-Sharaa, who leads Syria under a five-year transitional constitutional declaration developed with limited public input, faces pressure to consolidate control, deliver basic services, and prevent sectarian violence.
The threat of continued violence persists. The UN estimated 3,000 active ISIS fighters in Syria and Iraq, with most in Syria. In early 2026, thousands more ISIS detainees and ISIS-linked individuals escaped or were released as the national government took control in northeastern Syria. U.S. defense intelligence assessments flagged that Syrian forces have integrated some extremists and foreign fighters while exhibiting weaknesses in command and control. And in July, while French President Emmanuel Macron visited Damascus, a bombing rocked the city, injuring 18 people. The explosion occurred near the Four Seasons Hotel in Damascus, where sources reported that Macron was staying. Macron is the first European Union head of state to visit Syria following the collapse of the al-Assad regime.
These conditions create a central tension in Syria-U.S. relations: the administration is seeking to engage with and support the transitional government while managing substantial security and humanitarian risks.
U.S. forces completed their withdrawal from Syria in April 2026, ending an 11-year military presence that began in 2015 to counter ISIS. The withdrawal was conducted amid simultaneous U.S. operations against Iran called Operation Epic Fury. Prior to departure, U.S. forces transferred more than 5,700 ISIS prisoners from Syrian Democratic Forces-secured prisons to Iraq.
U.S. forces now operate from Jordan, Kuwait, Qatar, and the United Arab Emirates under Combined Joint Task Force-OIR, coordinating with Syrian forces against ISIS threats. The withdrawal marked a significant shift in U.S.-Syria foreign policy. The Syrian government forcefully reasserted security control over areas held by Syrian Kurdish forces that had long received U.S. training and support.
The geopolitical landscape surrounding Syria has become increasingly complex. Turkish forces remain in northern Syria with Syrian government permission, while Russian forces maintain facilities in western Syria subject to ongoing Syrian-Russian discussions. Israeli forces have conducted periodic strikes on Syrian government targets and unilaterally seized territory near the Golan Heights since December 2024.
Congress has authorized train and equip programs for Syrians since 2014, funded through the Counter-ISIS Train and Equip Fund. U.S.-backed integration agreements with the Syrian Democratic Forces were reached in January 2026, with some elements subsequently absorbed into state security bodies.
Political Stakes
The Trump administration has taken executive actions to dismantle the comprehensive Syria sanctions regime that had constrained U.S. engagement for years. As of June 2026, the United States no longer maintains a comprehensive Syria Sanctions program. This relief came through a combination of executive waivers and congressional action, including Congress's repeal of the Caesar Syria Civilian Protection Act, which had imposed sweeping sanctions on the Assad regime for war crimes when signed into law in 2019. And as of July 8, Trump announced that he would soon remove Syria's designation as a state-sponsor of terrorism in a letter to President al-Sharaa, after the two leaders met in Ankara.
In May 2026, President Trump named U.S. Ambassador to Turkey Tom Barrack as Special Presidential Envoy to Syria and Iraq. The administration is requesting $20 million for a possible phased restoration of a U.S. diplomatic presence in Syria and more than $54 million for diplomatic security. The U.S. Embassy in Damascus has been closed since 2012, with Czechia serving as the protecting power for U.S. interests in the absence of a U.S. mission.
For the Trump administration, the stakes involve balancing engagement with the transitional government against the risks of legitimizing leaders with terrorist designations and supporting forces with documented extremist elements. For Congress, pending legislation including S. 3172 and companion bills to further amend sanctions, along with appropriations provisions in H.R. 8595 authorizing nonlethal stabilization assistance and aid to Syrian minorities, reflect ongoing debate over the pace and scope of normalization.
Ethnic and sectarian violence against Alawite and Druze minorities has marred the transition. Transitional leaders have taken initial, limited steps to deliver accountability for violence since 2025 and made overtures to Kurds and others to promote unity. Indirect parliamentary elections have been held in most areas of Syria, with elections in eastern Syria occurring in March and May 2026. However, elections in Suweida had not been held as of the CRS report's release.
In May 2026, senior UN officials noted economic hardship-fueled protests in Syria, signaling public discontent alongside governance challenges. These dynamics complicate the administration's political transition strategy for Syria, and raise questions about the legitimacy and durability of the institutions being built.
The Bottom Line
The trajectory of Syria U.S. relations over the coming months will reveal whether engagement produces the stability and reform the Trump administration envisions, or whether it enables the consolidation of an unstable and possibly hostile state.
