Zack, Jenn, and Alex talk about perhaps the single worst humanitarian crisis in Syria’s civil war — the ongoing situation in Idlib, where 3 million people are trapped in a province under assault by Bashar al-Assad and his allies. They explain how we got to this point, why the situation is so dangerous, and what could happen next. References: Our colleague Jen Kirby wrote a great explainer on the conflict in Idlib. Jen mentioned the book Assad, or We Burn the Country, which you can find here. Alex reported on Assad’s “siege, starve, and surrender” strategy as his forces overtook Eastern Ghouta. Turkey does want to send Syrian refugees to a “safe zone” in northern Syria. Turkey invaded northern Syria to fight US-allied Kurds near its border.
