Turkey is about to invade Northeastern Syria with U.S. permission despite previous American security guarantees to the Syrian Democratic Forces (SDF). The U.S. has not yet announced a full withdrawal from Syria but U.S. forces pulled back from the border. ISW Research Director Jennifer Cafarella and Syria expert John Dunford will discuss what options the SDF has and how other actors, including ISIS and Iran, are prepared to exploit the possible chaos to follow.
