If there's any country that has the capacity not to control North Korea, but to influence North Korea, it's still China. The Chinese always say they have very little influence. They have more than they say they do. We should put pressure on them to do it and there's finally, we're seeing the first signs of a little bit of Chinese disaffection. At some point they're getting tired of the antics of this country. This is a dangerous ally for China to have. And the more Chinese can pressure them and put the economic screws on them, the better it will be for everybody.

Some governments are prepared to give up elements of sovereignty to address the threat of global climate change.

I think what Mr. Trump has made clear is that he would not undertake optional wars, what I have called wars of choice, a la, say Iraq in 2003 or Libya, for the purposes of transforming another country. It's not clear whether Hillary Clinton, if she were to have the opportunity, would do such a thing again or whether she would have taken a - the lesson from both Iraq and Libya that we ought not to be undertaking those kinds of wars of choice.

I've worked for four presidents, and I've concluded that almost nothing is inevitable. History is to a significant extent the result of the interaction of personalities and ideas. And so I don't believe war between the U.S. and China is in any way inevitable, and it's well within the province of diplomacy and statecraft to avoid it.

I think it was going to be hard to work with Russians on Syria. There is some potential overlap between the U.S. and Russia in that the Russians don't want to see the Syria situation unravel to a point where they have to escalate their own involvement. But at the moment, I don't see the U.S. and Russia on the same page in Syria. Russia seems much more interested in consolidating government control over liberated areas. It seems to me that the U.S. and Russia are proving they can disagree for independent reasons in any number of theaters.
