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.

Be careful about a policy generated with enthusiasm in the rush of a moment. It usually doesn't turn out well.

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.

It's said that Putin can't stand Hillary Clinton. I don't know that for a fact, but it certainly looks that way, but I think her approach to Russia stands up pretty well.

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

I'm one of the many people who has said that the Hillary Clinton we know in private was effective, strong, courageous, and funny. And the campaigner we saw was less so, more scripted. Many people have made that observation, and it was my observation, too, but I'm grateful for what she did.
