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.

Maybe it's my libertarian philosophy: but being in government is hard.

The Iranian government is the government that supplied the arms on the Karin-A to the Palestinian Authority several years ago, they are the world's largest central banker for terrorism, if they thought it was in their interest to give a terrorist group a nuclear weapon to use against America or against Israel, I don't think they'd hesitate.

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 real issue of dealing with proliferation of weapons of mass destruction: nuclear, chemical or biological is: What is your tolerance for risk? And my tolerance for risk for WMD proliferation is pretty close to zero. Because otherwise, we and our allies are at the mercy of regimes like Ahmadinejad and the mullahs in Tehran, or Kim Jong Il and the Hitler-in-the-bunker mentality in Pyongyang, or others who don't share our calculus on the value of human life.

Every country has an aspect to it that rubs up people the wrong way.

If Iran obtains nuclear weapons, then almost certainly Saudi Arabia will do the same, as will Egypt, Turkey and perhaps others in the region.
