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.

I believe that the Iraqis have an opportunity now, without Saddam Hussein there, to build the first multiconfessional Arab democracy in the Middle East. And that will make for a different kind of Middle East. And these things take time. History has a long arc, not a short one. And there are going to be ups and downs, and it is going to take patience by the United States and by Iraq's neighbors to help the Iraqis to do that. But if they succeed, it'll transform the Middle East, and that's worth doing.

To say that people around the world deserve the same, the same life that we have in the United States, the same freedoms that we have, that seems to me, humble. I think it's humble to say that the United States, which has been given so much, should give back.

Search for role models you can look up to and people who take an interest in your career. But here's an important warning: you don't have to have mentors who look like you.

You know, I look at Vladimir Putin as somebody who is an eye-for-an-eye kind of person. We questioned the legitimacy of his election in 2012, Secretary Clinton did - rightly, by the way. It did have - it was quite fraudulent.And so I think he's saying now, I'm going to show you that I can do the same thing.

You never cede control of your own ability to be successful to something called racism.

I'm very proud that we stood for the proposition that no man, woman or child should ever have to live in tyranny. We believed in democracy and promoted it.
