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."

The only thing that will stop Iran from getting nuclear weapons is regime change in Tehran.

I don't think Hamas will be satisfied simply ruling the Gaza Strip.

America needs an adult in the White House who knows how to deal with China.

I don't think I would have to run a campaign that's financed like General Motors.

There's no such thing as the United Nations. If the U.N. secretary building in New York lost 10 stories, it wouldn't make a bit of difference.

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.
