I think the tragedy of Barack Obama's presidency is that although a lot of people around the world really admire Barack Obama a lot, they don't admire the American political and economic model as much as they used to.

Fears don't exist in isolation. They tend to rise and fall depending on what people think they can do about them.

Foreign policy is a little bit like a guy who goes to Las Vegas. If you win too much, then you eventually bet the mortgage. You start to think you are infallible.

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.

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.

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

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.
