Diplomacy is not an end in itself if it does not advance U.S. interests.

There is no patriotic obligation to help advance the career of a politician who is otherwise pursuing interests that are fundamentally antithetical to your values. That's not the call of patriotism.

The Republican Party is the party of national security. There's hardly a national security wing of the Democratic Party anymore. So if we turn away from it, that'll be a big problem.

Everybody pursues their national interests. The only one who gets blamed for it is the United States.

It's not natural disasters that are to blame for the deprivation of the North Korean people, but the failed policies of Kim Jong Il.

The press tend to stick with that the people don't care about foreign policy in their daily lives and aren't concerned about it and so on and so forth. I don't think that's actually true.

I think the future of China's unknown, I don't know what direction it's going to go in. It could go in the right direction, it could. It could go in a very bad direction, too.
