President Donald Trump recently made the decision to pull U.S. troops out of northern Syria. Why was the U.S. there in the first place; where do things stand now with Turkey, the Kurds, and Syria; and what effect did that decision have on the fight against ISIS? Brett McGurk is the Payne Distinguished Lecturer at FSI and the Center for International Security and Cooperation. He previously served as Special Presidential Envoy for the Global Coalition to Defeat ISIS at the U.S. Department of State. In this episode, McGurk discusses why the removal of U.S. troops from Syria is a big deal, the effect it has had on the fight against ISIS and security in northern Syria, and what it signals to the rest of the world.
