The United States has completed a withdrawal of its troops from Syria, ending roughly ten years of military engagement in the country. The pullout raises urgent questions about the future of Kurdish forces (a non-Arab ethnic group that partnered with the US to fight the Islamic State militant group), who now face an uncertain security environment as rival powers and armed factions compete for influence on the ground. The shift in American posture is expected to reshape regional dynamics, with fragile negotiations among competing parties now determining Syria's political trajectory.
