In light of 50 years of bondage of Eastern Europe, [invading the Soviet Union in 1948 to prevent it from acquiring nuclear weapons] was probably a reasonable thing to do.

In the segregated South, education was almost like armor. It was a way to put yourself in a category where even with the slings and arrows and humiliations of racism and segregation, somehow you had better control of the situation. I always said my parents understood that you might not be able to control your circumstances, but they and their parents believed that you could control your reaction to your circumstances.

What surprised me was the angst at our democracy. And I understand it - I teach at a university and feel it in my students - but what I've tried to say to people is that we have amazing institutions, but nobody ever said we were perfect. We struggled before and we're struggling now, and we're going to struggle every day. We're a work in progress. That's why the American experience is so important for us to remember, and for us to be a beacon for others to enjoy those same rights.

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.
