I think that at the time, displaying "valor" was pretty far down on the list of things motivating me. By my generation, the notion that we were fighting to accrue personal glory seemed anachronistic.
But hey, you weren't part of that and I don't expect you to understand it. But for the guys that signed up and went rather than dodging the draft, they went where they were sent and did what was asked of them, and deserve your respect.
I guess my point is, when you denigrate an entire generation with such a broad brush in order to blame them for your lack of success, you're making a mistake, and it makes you sound kind of... immature.
In some ways, valor was in even greater display in Vietnam, as soldiers fought in smaller units often as tiny as 5 men, or in isolated outposts, and were more often required to display an individual courage.
There were a lot of MOH earned in Vietnam.
Thank you for your service.
