I use the word power broadly. Even more important than military and economic power is the power of ideas, the power of compassion, and the power of hope.

But we do have confidence in our institutions. We are not Russia. We have an executive that is constrained. We have a legislature that is real. We have a press that is free. We have courts that are independent. This is not Russia.

I believed Afghanistan was always going to be hard. It's the fifth poorest country in the world. And when you fly over it, you realize that there's not much there. And, of course, it has the problem, too, of being on that border with Pakistan in basically an ungoverned region that has given the terrorists a staging ground. So it's a very difficult place. But I do believe that the mission there can succeed if success is defined as helping the Afghans to prevent the Taliban from being an existential threat to the Afghan government.

I think all of us have really got to redouble our efforts, first of all, to pay attention to the K-12 crisis. The sad fact is that I can look at your zip code and tell whether you're going to get a good education. That's not fair. And secondly, I hope that all of us who were fortunate enough to have benefited will put our time, our resources and our efforts into making sure that kids, particularly kids without means, have a way to achieve.

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.

I certainly have no regrets about overthrowing Saddam Hussein. I'd do it again. And, yes, there are a lot of things that I think we'd all do differently. Maybe we made some erroneous assumptions about the fabric of the society in Iraq and about the solidity of some of the institutions. And yes, there are a lot of things I would do differently. I'd probably work to rebuild Iraq from the outside in, rather than concentrating so much on Baghdad, for instance.

I remember classes in college where the professor was espousing certain theories about how blacks were inherently less intelligent. But I learned a long time ago to give people the benefit of the doubt, not to assume that somebody was reacting to you because of race.
