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.

The only thing that makes battle psychologically tolerable is the brotherhood among soldiers. You need each other to get by.

There's no reason to do anything twice, and certainly no reason to do something that almost killed you.

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.

There is some evidence that average wave heights are slowly rising, and that freak waves of eighty or ninety feet are becoming more common. Wave heights off the coast of England have risen an average of 25 percent over the past couple of decades, which converts to a twenty-foot increase in the highest waves over the next half century. One cause may be the tightening of environmental laws, which has reduced the amount of oil flushed into the oceans by oil tankers.

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 decided to start a medical training program for freelancers, only freelancers. They're the ones who are doing most of the combat reporting. They're taking most of the risks. They're absorbing most of the casualties. And they're the most underserved and under-resourced of everyone in the entire news business.
