Fifteen years ago, there was this country called the Soviet Union that had over 10,000 nuclear warheads pointed at us... they're not there anymore. That's a good thing. And when people talk about how the world is more dangerous now than it was because we had these terrorists running around, my reply is, you know, a terrorist is like a buzzing mosquito. About 15 years ago, there was a great, big vampire bat; that's several orders of magnitude different from a mosquito. So the world is much safer - a lot safer than it was. It's not perfectly safe, but it's a heck of a lot safer than it was.
