I've speculated about what my life might have been like as a musician, but I'm afraid I came to the conclusion that I probably would've either been teaching piano or maybe gotten to play at Nordstrom's department store.

The moral case is, people say, "Oh they're not ready for democracy," but that's something someone who lives in a democracy would say about someone who doesn't live in a democracy. Well, if democracy is the highest form of human potential, then it can't be true for us and not for them. But, the practical case is democracies don't invade their neighbors. Democracies don't traffic in child soldiers. Democracies don't harbor terrorists as a state policy. So there's a reason to have more democratic states.

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.

So I think, if September 11 taught us anything, it taught us that we're vulnerable, and vulnerable in ways that we didn't fully understand.

Hillary Clinton is somebody of great intelligence. She is somebody who really loves this country, who speaks forcefully and well for American interests and values.

The United States has no credible evidence that Iraq moved weapons of mass destruction into Syria early last year before the U.S.-led war that drove Saddam Hussein from power.

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.
