I think the tragedy of Barack Obama's presidency is that although a lot of people around the world really admire Barack Obama a lot, they don't admire the American political and economic model as much as they used to.

Our sense of optimism, our can-do spirit, that's a source of great strength in America. But when there are no limits at all and we've gone through whole periods where we think everything has gone right, that's when disaster tends to strike.

Clinton is a very capable, conscientious person. I think she cares very deeply about policy. She knows a lot about how the government works, and I think those things are very important. You don't really appreciate those things until you get a guy like George W. Bush in the White House, and then you realize that when you don't have someone who knows or cares about government policy, a lot of bad stuff can happen.

I think the most inspiring thing that Americans can do for the rest of the world is struggle against the evils in our own society.

Foreign policy is a little bit like a guy who goes to Las Vegas. If you win too much, then you eventually bet the mortgage. You start to think you are infallible.

There's nothing wrong with being proud of America, believing that America can do great things. America can do great things, it has done great things. I think we have to have the self-awareness to recognize that the world is a very, very big place, that we could be a force for good things in the world, but we have to have the humility to recognize that sometimes even when we think we're acting from the best of motives our own idealism can be infected by self-interest. Other people in other countries can see it sometimes better than we can.
