The Vietnam War totally turned my life around. Some people's lives were eliminated or destroyed by the experience. I was one of the fortunate few who came out better off.

I'm not so sure that people consider homelessness to be as important as, say, the Vietnam War. One should never even try to equate them because, of course, they're tragedies on both sides of the coin.

I simply told people what I thought about the state of the war in Vietnam, and it was that we better get out of this.

It was my view then, and still is, that you don't make war without knowing why. Knowledge of course, is always imperfect, but it seemed to me that when a nation goes to war it must have reasonable confidence in the justice and imperative of its cause. You can't fix your mistakes. Once people are dead, you can't make them undead.

This looks like a real war zone to me. Thirty years ago, I was in Vietnam, and I haven't seen such devastation since then,

Vietnam was as much a laboratory experiment as a war
