This is the democratic process at work, What you're seeing with this process is the Iraqi people embracing American-style democracy.

Today's headlines and history's judgment are rarely the same. If you are too attentive to the former, you will most certainly not do the hard work of securing the latter.

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.

You are American, whether you profess Judaism, Catholicism, Protestantism, whether you adhere to Islam, or whether you believe in nothing at all. And you're as American as anybody else, whatever your religious beliefs. But try not to get caught up in media stereotypes of your neighbors and of your country. Think about people that you know and how they treat you. 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.

American national security and American economic interests, of course - every president, every secretary of state - that is the primary goal. As you are in this job and in the work, you begin to see, though, that in the long run, both American economic interests and American national security are better served when there are other decent countries in the world who are both your allies and even when your adversaries are acting more decently.

I'm a strong believer that you have to have an equal opportunity to fail and to try things that are hard. I always tell my students, "Don't just take things that are easy for you. If you're really good at math, don't take just math. Take classes that make you write. If you're a really great writer, but bad at math, take math and make yourself work your way through it."
