We're in a new world. We're in a world in which the possibility of terrorism, married up with technology, could make us very, very sorry that we didn't act.

But I want to just caution, it is not incumbent on the United States to prove that Saddam Hussein is trying to acquire weapons of mass destruction. He's already demonstrated that he's trying to acquire weapons of mass destruction.

We can't live true to our set of values unless American educational system is strong. I really believe that if we don't get that right we will not compete because we won't believe that our people can compete, and we'll turn inward. We won't lead. That will be bad for the world.

Power is nothing unless you can turn it into influence.

Out of struggle very often comes victory.

I think that one of the greatest challenges we have today is around education. One of the things that is dividing us more and more is whether you have good prospects or you don't. Do you live a neighborhood where the schools are good? If you don't, your kids may not read until the time they're in third grade. Do you at least have access to a community college that will give you job training skills so that if you don't go for four years you will at least come out with a decent job and a decent wage. Too many people don't have that opportunity.

I'm a strong believer that you have to have an equal opportunity to fail and to try things that are hard. I always tell my students, "Don't just take things that are easy for you. If you're really good at math, don't take just math. Take classes that make you write. If you're a really great writer, but bad at math, take math and make yourself work your way through it."
