After successful negotiations with Syria’s new government, President Donald Trump reversed long-standing US policy toward the country by lifting several sanctions and ending Washington’s cooperation with the Kurdish-led Syrian Democratic Forces (SDF). The move left the SDF without protection and effectively ended hopes for Kurdish autonomy in northeastern Syria under American backing. Following the shift, Syrian government forces captured large territories from SDF control on January 20, prompting the group to renew a ceasefire with Damascus that includes integrating SDF fighters into the national army.

The policy change marks a major geopolitical turn in Syria’s prolonged civil conflict, with Turkish President Recep Tayyip Erdoğan and Saudi Arabia reportedly playing key roles. The SDF, once a key US partner in the fight against the Islamic State, now faces isolation as Washington aligns with Damascus in the anti-IS coalition. US envoy Tom Barrack stated that the SDF’s original mission had effectively ended, angering Kurdish leaders who had relied on earlier US assurances.

Analysts suggest the withdrawal of US support signals the end of over a decade of Kurdish self-rule in Syria’s northeast, consolidating President Ahmed al-Sharar’s control over the country’s largest territory since the war began in 2012.
