I wish there were somebody I could be comfortable voting for. I might have to vote for Hillary Clinton, even though I have big reservations about her.

I mean, we're going to probably debate the Iraq war for at least as long as I'm alive.

The Western alliance should have supported the Sunni opposition against the Assad regime from the beginning. As far as Iraq is concerned, if it had stayed stable the way it was in 2008, IS would not have been able to expand in Iraq the way they did. The mistake was that Barack Obama withdrew the armed forces from Iraq too fast.

The Bernie Sanders phenomenon shows that it's not confined to Republicans. There is a general sentiment that America is on the wrong track.

I think, in the longer view of things, there is a very powerful pull in the direction of participatory government.

Look, I think the notion that theres a dogma or doctrine of foreign policy that gives you a textbook recipe for how to react to all situations is really nonsense.

I think Obama sees everything through one lens. Doing nothing in the face of the slaughter in Syria is not only shameful, it is unrealistic. This approach leaves Syria as a broken country and a breeding ground for extremists for decades.
