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.

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.

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.

I have been working since I was 20, and I'm 38. I actually once averaged out what I had made over my professional life. I think I could have made that much as a waiter or an insurance salesman. You know, I spent so many years in my 20's making $10,000 a year.

The Army might screw you and your girlfriend might dump you and the enemy might kill you, but the shared commitment to safeguard one another’s lives is unnegotiable and only deepens with time. The willingness to die for another person is a form of love that even religions fail to inspire, and the experience of it changes a person profoundly.

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.
