As Americans we like to believe that we're loved in international politics or that people like what we're doing. But we also recognize that we have an extraordinary responsibility to do what we think is right, and that sometimes what we do is not very popular.

I talked about the need for American leadership, I talked about the importance of the United States to a more peaceful world, a world that has been quite turbulent in recent years, and needs a strong American anchor.

But in terms of Saddam Hussein being there, let's remember that his country is divided, in effect. He does not control the northern part of his country. We are able to keep arms from him. His military forces have not been rebuilt.

I remember at the time of 9/11 that there were women who went out of their way to escort Muslim women to grocery stores because they wanted to be sure that they didn't experience any prejudice. And so I'm not one who believes that America is a country that's intolerant. It's the most tolerant country in the world, and I really think that it's unfortunate that a number of people are trying to paint America with this brush. I just don't see it.

We're in the middle of the transformation of a society that has handled its politics through repression to a society that will handle its politics through democratic institutions.

I studied piano from the age of three. My grandmother taught piano. I stayed at her house during the day while my parents worked. I obviously wanted to learn to play. And so she asked if she could teach me, and my mother said don't you think she's too young. My grandmother apparently said no. So I could read music before I could read, and I really don't remember learning to read music. So for me it's like a native language. When I look at a sheet of music, it just makes sense.

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.
