. . . or start a genocide in the third world. . .
If you’re referring to Nixon’s 1970 invasion of Cambodia (for several months? ?) and the secret bombing which both preceded, and followed this invasion, well, hell, the North Vietnamese ran supply lines and massively disrespected Cambodia’s sovereignty, too, and also share moral responsibility.
The genocide is a full five years later.
I guess like saying the Nazi Holocaust is mainly the responsibility of good Germans who didn’t fight early or hard enough against the Nazis, we should say the prime responsibility for the Cambodian genocide was the Cambodian leaders, whether they be political, business, informal leaders or just plain citizens who didn’t fight early or hard enough against the damn Khmer Rouge.
And secondarily, China who was the main sponsor for the Khmer Rouge. And just like it took us in the United States a shitload of time to acknowledge that, yes, we pretty much committed genocide against Native Americans, it’s going to take the average Chinese citizen a while to wrap their mind around this and acknowledge, yes, this is a pretty sorry chapter in their nation’s history.
