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.

At no time did I intend to, or do I believe that I did put forward false information to the American people.

I get letters from kids from all over the country. I always try to answer them because there were people I looked up to in my youth and just wanted to be in contact with. It's also important to realize that you find your role models in a lot of different places. I've never believed that your role models have to look like you. You can find them in all sort of colors, shapes and sizes.

The essence of America - that which really unites us - is not ethnicity, or nationality or religion - it is an idea - and what an idea it is: That you can come from humble circumstances and do great things.

I have no doubt that as the Iraqi security forces get better, and they are getting better and they are holding territory and they are doing these things with minimal help, that we are going to be able to bring down the levels of our forces. And I have no doubt that that's going to happen in a reasonable time frame.

I'm actually genuinely optimistic about the United States and what's possible in the United States. And when you're out here, you see Americans across racial and economic and socioeconomic lines working together. And you maybe get a little bit less cynical than when you sit in the seat of kind of the epicenter of it all.

It has been hard to muster the resources to support fledgling democracies and to intervene on behalf of the most desperate. The AIDS orphans in Uganda, the refugee fleeing Zimbabwe, the young woman who has been trafficked into the sex trade in Southeast Asia. It has been hard, yet this assistance together with the compassionate work of private charities, people of conscience and people of faith, has shown the soul of our country.
