My reporting in Africa wouldn't be political per se, but it's certainly the point of my reporting - and of a lot of other reporters I know: Human suffering is bad, and if reporting stories about it brings it to light and someone does something, that's part of the point of journalism. And it's a thin line between that and activism, and you have to be careful about that.

Here's an easy way to see if a war movie is being truthful: If you see an explosion on a faraway hillside and the sound of the explosion and the detonation of the bomb happen at the same time - if they're putting the sound and the vision together in the same moment - they're going toward our cultural understanding of war, not the reality of war.

Maybe the ultimate wound is the one that makes you miss the war you got it in.

I had grown up during Vietnam. I had no connections to the U.S. military, and I had a pretty cynical default opinion about the U.S. military.

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 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.

If you shell a military base and happen to kill civilians, you have not committed a war crime; if you deliberately target cities and towns, you have.
