In the military I could exercise the power of being automatically respected because of the medals on my chest, not because I had done anything right at the moment to earn that respect. This is pretty nice. It's also a psychological trap that can stop one's growth and allow one to get away with just plain bad behavior.

Vietnam was the first time that Americans of different races had to depend on each other. In the Second World War, they were segregated; it was in Vietnam that American integration happened in the military - and it wasn't easy.

For every veteran who goes through a divorce, a wife goes through one, too. For every veteran alone in the basement, there is a wife upstairs, bewildered, isolated and in despair from the dark clouds of war that hangs over family life.

When I first got back from the war, I said, 'I'm gonna write the Great American Novel about the Vietnam War.' So I sat down and wrote 1,700 pages of sheer psychotherapy drivel. It was first person, and there would be pages about wet socks and cold feet.

I mean... if you're raised as a decent human being, killing somebody is against every moral thing you've ever been taught. And so, generally, in combat it's 'krauts,' the 'gooks,' the 'yanks' - whatever you want to do to try and make it so that it's not a human being.

I don't want any romantics to go into the military. I'm not a pacifist. I think we need a military, and the better one we have, the better off we are. I don't want kids going in there thinking that it's John Wayne on Iwo Jima. That's not healthy.

We all want to be special, to stand out; there's nothing wrong with this. The irony is that every human being is special to start with, because we're unique to start with. But we then go through some sort of boot camp from the age of zero to about 18 where we learn everything we can about how not to be unique.
