Do you really think that our troops died in vain in Vietnam? I don't. In fact, I visited Vietnam a few years ago and I must say that thanks to the U.S. it has turned out to be a great country. We are going to be having close ties with the country shortly and be an intrical part of President's Bush's Global initiative (regardless of agreement or not that is not the point at this time). I think the country of Vietnam is better because of us. Sorry can't seem to agree with everyone that the military's lives were waisted in Vietnam.
It is not about the fine men that gave everything in Vietnam. It is still a VERY sore point about those that were left behind. You may be too young to understand:
