When a US drone strike killed Iranian commander Qasem Soleimani, it didn't just reverberate in Iran. It was supposed to be a huge blow to Syria's authoritarian leader Bashar al-Assad, his biggest international ally and the leader of Iran's proxy militias waging a reign of terror in Syria now gone. And yet this week, a Russian-backed Syrian government offensive aimed at the country's last rebel-held stronghold has forced more than half a million people -- 80 percent of them women and children-- to flee their homes since December. Washington Post Foreign Policy columnist and CNN Political Analyst Josh Rogin joins SE to discuss when the atrocities will end and whether this crisis can be solved politically.
