The United States intervention in Syria is the United States-led support of Syrian opposition and Rojava during the course of the Syrian civil war and active military involvement led by the United States and its allies – the militaries of the United Kingdom, France, Jordan, Turkey, Canada, Australia and more – against the Islamic State of Iraq and the Levant (ISIL) and al-Nusra Front since 2014. Since early 2017, the U.S. and other Coalition partners have also targeted the Ba'athist government in Syria and its allies via airstrikes and aircraft shoot-downs.
