Reassessing the U.S. Withdrawal from Syria and Its Impact on the Fight Against ISIS
Summary
In this retrospective analysis published in March 2026, author Thanassis Cambanis revisits his 2024 argument that the United States should strategically withdraw from Syria while maintaining robust counter-terrorism efforts against the Islamic State. He originally advocated for an orderly withdrawal that would strengthen U.S.-Iraq relations and minimize disruption to anti-ISIS operations, but the actual withdrawal fell far short of that vision. Instead, the departure created dangerous power vacuums and chaos, with the new Syrian government moving to absorb Kurdish-controlled territories once the U.S. abandoned its Kurdish partners. The transition of high-risk Islamic State detainees was poorly managed, with an unknown number potentially escaping during the bungled handover, and the U.S. received little diplomatic goodwill from either Syria or Iraq in return for its concessions.
Key Takeaways
- 1. The U.S. withdrawal from al-Tanf and handover to the Syrian government did not unfold in the organized, strategically beneficial manner that Cambanis had originally recommended
- 2. The abandonment of Kurdish partners left them vulnerable to absorption by the new Syrian government, undermining a key U.S. allied relationship in the region
- 3. The chaotic transition of Islamic State detention facilities raised serious concerns about the potential escape of high-risk ISIS detainees
- 4. The U.S. failed to leverage its withdrawal to gain meaningful diplomatic credit or strengthen ties with either the Syrian or Iraqi government
- 5. Iraq arguably did the U.S. a favor by accepting a bulk transfer of Islamic State detainees, rather than the other way around, reflecting a weak U.S. negotiating outcome
