I'm obviously aware that people are quite focused on the economy rather than foreign policy issues, but that is something that should and can be altered as people see the nature of the threats around the world that we face.

It's very personal in its politics, very bitter and very negative.

A lot of people have said to me, 'That's a great idea, running for president. You'll get booked for more speeches. You can write a book.'

I think the regime in North Korea is more fragile than people think. The country's economic system remains desperate, and one thing that could happen for example would be under a new government in South Korea, to get the South Korean government to live up to its own constitution, which says any Korean who makes it to South Korea, is a Korean citizen. A citizen of the Republic of Korea. And you could imagine the impact that would have inside North Korea if people thought, "If I could get out and make it to South Korea, I could have a different life."

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

The International Criminal Court uses a prosecution-only approach. And by putting their fate in the hands of outsiders, countries are really dodging responsibility for actions taken in the name of that country, in the name of the people in that country, by the people of that country themselves. That is, I think, fundamentally the wrong direction to go in.

I think the Russians basically don't think the North Koreans and the Iranians have the capabilities to get weapon systems that can threaten them, or that if they do the Russians know how to handle them and that that's the reason that it's all the more important that Russians be involved in the sale of high-end conventional weapons, the Bushehr nuclear reactor in the case of Russia and Iran, and similar kinds of relationships.
