The United States comes in 1945 and we basically blow the whistle.

Realism is important in foreign policy. You have to be realistic about what you can achieve, and about the pitfalls, and problems along the way, of which there are plenty. Nothing is easy. It's always rough.

I believe the liberal international order is under assault from Russia, and from other authoritarian regimes, and it is being questioned from within the West by nationalists, by nativists, and by people who doubt our - doubt the values of the West. We've gone through periods like this before; in the '70s, after Vietnam and Watergate, and certainly in the '30s, when people thought liberal democracy was dead, and the future belonged either to the fascists or the communists.

I am not one of these people that believes that Russia is doomed, or somehow, you know, inevitably disposed to act according to its worst traditions. But all the more reason, therefore, to resist their aggression and take it seriously.

John Kerry tried to work with the Russians on Syria, and the man was honorable, because he was trying to do the right thing, and frankly, playing a very weak hand, a hand that was weak not because of him, okay. He did the best he could, but I will say this to his enormous credit: he never offered a dirty deal. You can have Ukraine if you only help us out on Syria. Never - he never did that.

Putinsim is not necessarily the end state for Russia. Russia has moved in many directions since the early 1980s.
