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

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."

By creating a prosecutor who is overseen over by a court, they are melding executive and judicial power in a way that can lead to terrible abuses - as the founders of America understood full well. It's why they created a system of separated powers - to set up a constitutional mechanism that would enhance freedom, by making sure that no one's accumulation of power could predominate over [that of] others.

A strong State Department to me means a corps of career officials who believe that their job is to advocate America's interests and who are trained in effective advocacy, not schooled in accommodation.

Let me ask, who died and made him king? Who gave him the authority to endanger 300 million Americans? That's not the way it works, and if he thinks he can get away with that, he's got another think coming.

Just as that little opening in the Iron Curtain that Hungary created caused a flood of people out, and ultimately the beginning of the end of communism in Europe, if you could get refugee flows coming out of North Korea, while there'd be a very difficult humanitarian problem in the short run, both for China and South Korea, in the long run it would lead to reunification.

What we want for the Iranian people is control over their own government, which they don't have now. So you would do it through supplying resources and support from the outside to the indigenous people who are already quite unhappy. The mullahs have made hash of the economy since 1979, there's a huge amount of economic dissatisfaction. The young people, who are pretty well educated and sophisticated, know they could have a better life than this strict Islamic law.
