I think, in the longer view of things, there is a very powerful pull in the direction of participatory government.

I told my father I had to try political science for a year. He thought I was throwing my life away.

Saddam Hussein had nerve gas and used it against his own people, he had used chemical weapons against the Iranians and he almost had a nuclear bomb in 1981 and in 1991. And he had been caught with anthrax in 1995 by the UN inspections after denying that he had it.

China, in the future, is going to have even more nuclear capability than it has had in the past. I don't believe that they have anything to fear from the United States, and I frankly don't believe they do fear the United States.

I've met quite a few dictators up close and personal in my life.

Every math curriculum in the world is based on the idea of hand-calculating, and most of what you're teaching is how to calculate. And I think the resistance to this is very variable.

History is just littered with problems that were solved that were supposed to be impossible.
