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.

No matter how many people you kill, using a machine gun in battle is not a war crime because it does not cause unnecessary suffering; it simply performs its job horrifyingly well.

How do men act on a sinking ship? Do they hold each other? Do they pass around the whisky? Do they cry?

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.

Soldiers join the military to serve their country, but when bullets are flying, it's hard to fight for an abstract notion like patriotism. They're fighting for the people standing next to them, and it doesn't matter who's a Republican or a Democrat, or who's black or white or Christian or Muslim or gay or straight. If Congress and all Americans could manage to ignore those differences, we would have a perfect country, but somehow we cannot rise to that level of nobility.

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.

At 19, your brain hasn't finished wiring itself. So the first time you have a good friend die, most people don't go through that at 19. Soldiers do. They're facing life in this accelerated, compressed form, and a lot of times, they're not ready for it.
