I won’t watch Ken Burns’ take on this. The Best and the Brightest got us involved, then tried to micro-manage the conduct of the war. A lot of good men lost, then thanks to the Dems we totally abandoned the Vietnamese which also led to genocide in Cambodia. What the heck... a thread on Viet Nam could run to one thousand posts and we still wouldn’t address all the issues.
Military strategists going forward should study Vietnam for how not to fight a war.
As a pretty advanced bar fighter, with the scars that go with it, you can’t do it half assed. /fight to win.
