War is society's dirty work, usually done by kids cleaning up failures perpetrated by adults.

'Matterhorn' is my metaphor of the Vietnam War - we built it, we abandoned it, we assaulted it, we lost, and then we abandoned it again.

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 mean, if you're proud of what you've done when you've served in the military, well then we call that bragging. And if you are unhappy about what happened, we call that complaining. And so what are you going to do?

And I think that it's - the military has actually made improvements, so people are considering post-traumatic stress disorder as, at the least, a possible psychological problem. You know, when I was in Vietnam, it was just considered malingering. And we're making progress.

I grew up in Oregon, where as a teenager I worked with my grandfather Axel on his i shing boat at the mouth of the Columbia River.
