I know lots of vets from that war and many were more perturbed that there was seemingly no will to win it.
It was a politically infected war instead of a straight out military war and that more than anything betrayed some soldiers and those in Nam that fought with us.
Many people were toughened by that war to take on many professions. I know lots of CEOs, doctors, professional athletes who served that got their discipline from the military, at least according to what they tell me.
Some were shot up and never took their purple hearts because they saw people who lost a limb. Very UN-John Kerry, God bless them.
Many were introduced to excessive drinking and recreational drug abuse and those types had lots of stalled lives when they came back.
