"Every chance at destabilizing [Bashar] Assad... the bombing campaign causes a flood of refugees into Jordan, there's already half a million in Jordan. I think a bombing campaign - I think it's hard to argue that a U.S. bombing campaign is going to cause less refugees. And I think it causes more refugees and more of a humanitarian disaster. I think it causes, or allows, the risk of Israel being attacked with a gas attack to go up, if we attack Assad. So there's all kinds of bad things."
