There are real threats but there's a difference between recognizing real threats and an irrational kind of apocalyptic threat.

I hope Barack Obama puts another woman on the Supreme Court. And this time, I hope it's a woman with kids.

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.

It's easy to see why conservatives would be salivating at the thought of a Hillary primary challenge. Presidents who face serious primary challenges—Ford, Carter, Bush I—almost always lose. The last president who lost reelection without a serious primary challenge, by contrast, was Herbert Hoover. But in truth, the chances that Obama will face a primary challenge are vanishingly slim, and the chances that he will lose reelection only slightly higher. No wonder conservatives are fantasizing about Hillary Clinton taking down Barack Obama. If she doesn't, it's unlikely they will.

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.

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.

When you talk about the security and safety of average Americans it doesn't do average Americans a lot of good to expand America's military footprint if the daily lives of average Americans are being undermined by the fact that we're no longer able to compete in a global economy. I think that's the kind of human security we have to pay more attention to.
