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...

For one thing I tend not to see myself in various moulds that people fit me into.

There's a lot of money to pay for this ... the oil revenues of that country could bring between $50 and $100 billion over the course of the next two or three years...We're dealing with a country that can really finance its own reconstruction, and relatively soon.

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

That sense of what happened in Europe in World War II has shaped a lot of my views.

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.

Putin is behaving in a very dangerous way. And Donald Trump sounds as though he would simply sit back and allow that to go on. I worry about where that would end up.
