I got a letter from 13-year-old Ryan from Belfast. Now, Ryan, if you're out in the crowd tonight, here's the answer to your question. No, as far as I know, an alien spacecraft did not crash in Roswell, New Mexico, in 1947. And, Ryan, if the United States Air Force did recover alien bodies, they didn't tell me about it, either, and I want to know.

A world without walls is the only sustainable world. . . . If the world is dominated by people who believe that their races, their religions, their ethnic differences are the most important factors, then a huge number of people will perish in this century.

For too long we've been told about 'us' and 'them.' Each and every election we see a new slate of arguments and ads telling us that 'they' are the problem, not 'us.' But there can be no 'them' in America. There's only us.

North Koreans are irrational to some extent, but I don't think they're totally irrational. I think they watch American cable channels. I think they watch the European cable channels. I think they, their decision makers keep up more than we know. And I think they want us to think they're a little crazy.

I've been talking about income inequality in America for twenty years, and when I was president, people didn't pay much attention to it, probably because wages were going up. But I don't think I've given a single solitary speech since I left office that I hadn't talked about it. It's a problem around the world and within the United States. So these people have put that on the agenda.

From New Hampshire forward, for reasons that absolutely mystified me, the press thought the most important issue in the race was the middle class tax cut. I never did meet any voter who thought that.

When times are tough, constant conflict may be good politics but in the real world, cooperation works better. After all, nobody's right all the time, and a broken clock is right twice a day.
