The American-led intervention in the Syrian Civil War refers to the American-led support of Syrian rebels and the Syrian Democratic Forces (SDF) during the course of the Syrian civil war, including Operation Inherent Resolve, the active military operation led by the United States, and involving the militaries of the United Kingdom, France, Jordan, Turkey, Canada, Australia, and others against the Islamic State of Iraq and the Levant (ISIL) and al-Nusra Front since 2014. Beginning in 2017–18, the U.S. and its partners have also targeted the Syrian government and its allies via airstrikes and aircraft shoot-downs, mainly in defense of either the SDF or the Revolutionary Commando Army in al-Tanf.
