I think one has to say it's not just simply a matter of capturing people and holding them accountable, but removing the sanctuaries, removing the support systems...

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.

If a cat sits on a hot stove once, it will never sit on a cold one either.

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

The use of force to liberate people is very different from the use of force to suppress or control them, or even to defeat them.

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.

To stay back from an intervention is not always a good solution.
