AFGHANISTAN, August 3 - Iran, Russia, and the Syrian regime are coordinating a coercive campaign to expel the United States from Syria. This campaign poses a serious risk to US forces in Syria and US interests in the Middle East. Iran and the Syrian regime have surged forces and materiel to the line of contact with the Syrian Democratic Forces (SDF) in northeastern Syria from July 7 through 12 July. Both have deployed additional forces and materiel to the area since then at lower rates. The Iranian and Syrian deployments to eastern Syria have occurred alongside growing operational coordination with Russia. Russia has provided intelligence to Iran while conducting more aggressive flights against US forces in Syria since mid-March. Iran, Russia, and the Syrian regime also are coordinating an information operation that falsely claimed the deployments were to protect against a US-SDF attack into regime-controlled territory. US forces are in Syria under Combined Task Force Operation Inherent Resolve, which aims to militarily defeat ISIS through partnerships with the SDF and International Coalition partners.
