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.

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 the president Donald Trump had connected the Jerusalem question to some other positions, linking it to Israeli and Palestinian behavior or putting the Jerusalem statement in a larger context of U.S. policy, it could have potentially advanced the peace process. But I don't see how singling it out might help.

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.

Well, we ought to make clear to everybody that the next Korean War, if one were ever to happen, is going to be the last Korean War because it's going to end with a unified peninsula, and it's go to be under Seoul, not Pyongyang.

Donald Trump is much more suspicious of international institutions; much more skeptical of the contributions that America's traditional allies have made; more willing, in some cases, to entertain the possibility of getting along with countries who some would call an adversary, such as Mr. Putin's Russia.

Television was our chief tool in selling our policy.
