Bad news is dramatic. It makes good TV. If there's a firefight on the same day that a school opens up, the media will show the firefight even though the school is way more important and will affect the community for much longer.

I think human society for tens of thousands of years has sent young men out in small groups to do things that are necessary but very dangerous. And they've always gotten killed doing it. And they've always turned it into a matter of honor and a way of gaining acceptance back into society if they survived.

Right now, America doesn't ask us to do anything besides pay taxes. We don't even have to vote. But as psychologists will tell you, when you have to sacrifice for something, you value it more. What about national service for young people? Everybody between 18 and 24 could spend a year or two working for this country in some capacity. It'd be an amazing thing. And it would mix this country racially, culturally, economically.

Each Javelin round costs $80,000, and the idea that it's fired by a guy who doesn't make that in a year at a guy who doesn't make that in a lifetime is somehow so outrageous it almost makes the war seem winnable.

Combat isn't where you might die -- though that does happen -- it's where you find out whether you get to keep on living. Don't underestimate the power of that revelation. Don't underestimate the things young men will wager in order to play that game one more time.

I think, unfortunately, we live in a world where people attack other people and I think a legitimate rationale for war is the saving of human life, the saving of lives of people who cannot defend themselves.

If hardship brought out the worst in people, the human race wouldn't have survived. Right after 9/11, for instance, the murder rate actually went down in New York City. In World War II during the Blitz, the civilians of London were bombed almost every night for six months, but psychiatric admissions declined.
