If you want to read a few good books on that part of your life, I would suggest "Vietnam: The Necessary War" by Michael Lind which goes into the whys behind the war as seen from the perspective of decades later, and "Stolen Valor" by B.G. Burkett which goes into how certain politically motivated groups worked to turn the public against the soldiers.
Exactly, of what 'value' is a 'Worldview'...?
