America is not an ethnostate. We are not rooted in blood and soil.

Realism as a foreign policy doctrine means basically you don't care about values; you consider them a luxury, and it leads to a kind of acquiescence in spheres of influence. Now, spheres of influence sound good if you're a graduate student, or a certain kind of - an academic with a certain habit of mind. But in fact, spheres of influence don't work out very well, certainly not for the victims, and there are always victims.

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.

We did really well for a generation after 1989 and the fall of communism. Our liberal values expanded in the world, our prosperity expanded.

Republicans - Reagan but also George W. Bush - believed in freedom, and they believed in America's role. To have the governing party speak in terms of a zero-sum world, or speak in terms of America's purpose as no more than grabbing the largest share possible in the short run, goes against our foreign policy tradition that goes back to 1900, really.

There are a lot of policies that don't work out that are nevertheless worth doing.
