It doesn't matter if it was "wonderful" or not. It was the government the Vietnamese wanted.
Ho Chi Mihn was a national hero for resisting the French and the Japanese.
The people we propped up were French collaborators who were robbing the country blind.
But since we were talking about Cambodia, let's talk about Cambodia.
The king of Cambodia, Norodom Sihanouk, wanted to keep his country out of the war. Yes, the Vietcong were using his border areas as bases, but by and large, he wanted to keep out of it.
We proceeded to bomb the country and encouraged a coup by Lon Nol, who was immediately hated by his own people.
And when we pulled out, Lon Nol and his people were quickly deposed. Really nothing to do with gun control and more to do with 'You fucking lost."
Ironcically, the Vietnamese were the good guys in this situation, as they invaded Cambodia to depose the crazies who were slaughtering their own people.
