I was in the U.S. Army in Vietnam. I was pretty much of a mess when I got back so staying in wasn't a choice for me. And the 'wonderful welcome' we got on our return didn't help matters much either. I got burned out on the military pretty fast after that. But I was like you when I first went in. All gung ho and ready to serve my country. That is why I said give it a year and talk to me about it then.
And Brad, agreeing or not with a war doesn't diminish your responsibility. Do you really believe I thought Nam was legitimate?
