What the hell just happened in Syria? We asked one of the sharpest scholars on the subject to give us a primer. Aaron Zelin is a fellow at the Washington Institute for Near East Policy, where he also directs the “Islamic State Worldwide Activity Map” project. He’s also a visiting research scholar in the politics department at Brandeis and the founder of the website Jihadology. His first book is titled Your Sons Are At Your Service: Tunisia’s Missionaries of Jihad, and his forthcoming book covers the history of Syrian jihadism.

We talk about the entire history of Syria, as it faces what could be a turning point. For two clips of our convo — on the evil of the Assad dynasty, and the sudden fall of Bashar al-Assad — pop over to our YouTube page.
