There was no silver bullet that could have prevented the 11 September attacks. There was nothing demonstrating or showing that something was coming in the United States. If there had been something, we would have acted on it.

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 the United States has done hasn't always been liked or popular. But if you look at some of the most populous places in the world - China, India - the United States is not only respected but, in fact, popular.

I'm a great believer in the fact that as you get to know someone, it matters not what religious background they have, or what their nationality is, or where they came from. And I think that's how Americans really do relate to each other on a personal level.

My favorite quote is Thomas Jefferson`s "The God who gave us life gave us liberty at the same time." Well, he was a slave-owner. But these institutions, while they weren't perfect at the time, did allow people to prosper and to continue to struggle and build toward them. That's what you need, is good institutions and I think people will eventually live up to them.

Self esteem comes from achievements. Not from lax standards and false praise.

If you're always in the company of people who agree with you, you're going to think of people who don't agree with you as venal or stupid. I constantly tell my students that if they're in the company of people who always say "amen" to what you say, find other company. And that is the source of illiberalism, when you are unable to listen to someone who thinks differently. That's when democracies are in trouble.
