• U.S. troops have been in Syria for over a decade, with a primary mission to combat ISIS and a secondary role in countering Iranian influence.
• The current U.S. force in Syria stands at approximately 900 troops, mainly stationed in the Kurdish-controlled northeast and at al-Tanf base.
• Despite ISIS losing territorial control by 2019, sleeper cells continue to launch attacks, necessitating the ongoing U.S. mission.
• Ties between the U.S. and Syria's interim government have warmed, with Syria joining the global coalition against ISIS, though not officially Operation Inherent Resolve.
