Ted Cruz calls them "purple unicorns," but in this episode, Dr. Daniel Serwer argues that there is a moderate opposition in Syria and they're worthy of international support. Also discussed: how to deal with illiberal rebels, how to assuage Alawites and other minorities, whether the Free Syrian Army still exists, the prospects of Balkanization, and the outcome of the Riyadh opposition talks and Security Council resolution 2254.

Dr. Serwer is the Director of the Department of Conflict Management at the Johns Hopkins School of Advanced International Studies, and he blogs at peacefare.net.
