I’ve got a lapel pin that shows a GI in front of a map of Vietnam and says “We Were Winning When I Left”. True. US military never lost a battle; war was not lost but abandoned in Washington DC. Sad to see same thing happening to our troops today.
What is interesting is the number of veterans that served there prior to 1970 that believe the war was unwinnable.
Technically, there was no anti-war movement after 1970, only a pro Communist movement.
"The Long Way Home Project" was a good documentary.
