[Bashar] Assad himself has said on several occasions recently that if the people of Syria don't believe I should be there in the future, then I would step - I would leave. He has said it. He has, on occasion, hinted that he wants a political settlement of one kind or another. I think it's up to his supporters, his strongest supporters, to make it clear to him that if you're going to save Syria, Assad has made a set of choices - barrel bombing children, gassing his people, torturing his people, engaging in starvation as a tactic of war.
