Leading in a complex world means recognizing the simple things you can do to make things better.

The problem here is that there will always be some uncertainty about how quickly Saddam can acquire nuclear weapons. But we don't want the smoking gun to be a mushroom cloud.

I certainly think that the world views the United States as a place to be respected. All over the world our values are respected; who we are, a place that you can come and come from modest circumstances to great things, that's respected.

Any time you have a situation in which you are calling for more time rather than calling for Iraq to immediately comply, it plays into the hands of Saddam Hussein.

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.

Everywhere that I go in the world, people desperately look to American leadership in all of their world's most difficult problems. You can look at any region of the world and the United States is still the country to which those regions look for leadership.

We've got to get back to a sense of an American identity, and that identity is not nationality or religion or ethnicity. It is a particular idea, and that idea is that you should live in liberty and you should be able to pursue happiness.
