Obviously there were some Vietnamese who benefited from our occupation of their country, but I agree with MOH recipient & former Marine Commandant, Gen. David M. Shoup, who said:
"I believe that if we had and would keep our dirty, bloody, dollar-soaked fingers out of the business of these nations so full of depressed, exploited people, they will arrive at a solution of their own—and if unfortunately their revolution must be of the violent type because the "haves" refuse to share with the "have-nots" by any peaceful method, at least what they get will be their own, and not the American style, which they don't want and above all don't want crammed down their throats by Americans."

Amendment 13 bars involuntary servitude "except for punishment of a crime against the state" yet military types almost universally condemn those of us who refused to fight in unconstitutional wars. Are they hypocrites or fools? These liars sacred oaths mean nothing.
