Unless we improve our ability to provide a quality education for underprivileged kids, we're not going to really overcome in a massive way our past.

I've been an athlete all my life. I was a competitive figure skater, and then when I realized skating was not an adult sport I took up tennis and played that quite seriously from the time I was about 18.

I feel that we're dividing along class lines for the first time in our history. Now one thing that has happened in this reaction to globalization is that the elites are not respectful of the values of those who are ordinary citizens, so we seem to be dividing ourselves into ever-smaller identity groups, each with its own narrative, each with its own grievance, and that's a problem.

There's no doubt that it's still a dangerous place, Afghanistan. The fortunate thing is that the United States was helping to provide security for Chairman Karzai. And it shows that the United States is committed to that regime.

Education is transformational. It changes lives. That is why people work so hard to become educated and why education has always been the key to the American Dream, the force that erases arbitrary divisions of race and class and culture and unlocks every person's God-given potential.

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'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.
