Globalisation thus implies that sovereignty...needs to become weaker.

I think Hillary Clinton is more suspicious, clearly tougher on Russian policy in Ukraine, Georgia, Syria; more willing to support sanctions; not against negotiating with Putin, but I would say tougher and more skeptical. And Donald Trump has talked about revisiting policy towards Ukraine, revisiting policy about sanctions towards Russia, not as quick to criticize Putin for what he might be up to in Syria and propping up the regime there - so just seems to be more open to the possibilities of working out some kind of a - I guess you'd call a modus vivendi with Putin.

Globalisation thus implies that sovereignty...needs to become weaker.

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.

You cannot be effective if those who work for you are not. So building their effectiveness ought to be a priority.

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.

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.
