Hillary Clinton is pretty much what we would call a foreign-policy realist, someone who thinks the purpose of American foreign policy should be to adjust the foreign policies of other countries, work closely with traditional allies in Europe and Asia towards that end.

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

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.

The U.S. position on Jerusalem was not the reason why there hasn't been progress towards peace. The reason is that both the Israeli government and the Palestinian leadership are divided. And there is an enormous gap between Israelis and Palestinians. To say that this decision is only recognizing reality, that Jerusalem is the actual capital of Israel - well, that's true. But it's a selective recognition of reality.

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.

States would be wise to weaken sovereignty in order to protect themselves.

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.
