The solution to North Korea is the reunification of the Korean Peninsula. China could influence the North; it supplies 80 to 90 percent of North Korea's energy. The United States have to put pressure on China in order for China to pressure North Korea.

I'm not saying that you need a State Department that looks like the litigation department of a major law firm. But you need people who are not afraid to make the case for the United States, who are not afraid to stand their ground, not afraid to be isolated in international organizations when that's the correct approach for our diplomacy. This is a cultural change that has to be effected through incentive systems, promotion systems, career training systems. This is not something that you can do with the stroke of a magic wand, it's going to take years to make this change.

It was right to overthrow Saddam Hussein. It was the regime itself that was a threat. I think in hindsight, what I would have done is turn authority back over to Iraqis much more quickly and say: "Your country, you figure out how to run it."

I think the International Criminal Court could be a threat to American security interests, because the prosecutor of the court has enormous discretion in going after war crimes.

If a prosecutor in The Hague decides that the U.S. has not followed through effectively on an investigation - is unwilling or unable to carry it through - then that person, that prosecutor, in an unreviewable fashion gets to second-guess the United States? That is unacceptable. That is an assertion of authority over and above the U.S. Constitution.

I don't much believe in bumper sticker characterizations of foreign policy.
