History devolved more into melodrama than tragedy. America was no longer exceptional — and thus in no position to criticize a Cuba as undemocratic or condemn the Iranian mullahs as murderously theocratic
They setup a straw man of prefection (that never existed) and demand that until America meet these standars we can't criticize anyone else.
Remember what Jean Kilpatrick called them "The Blame America First Crowd". Pol Pot and his gang of thugs murder 1/3 of their people? It's America's fault, by bombing them we drove them insane. The Soviets run a huge slave labor camp system? It's America's fault, by invading them after WWI we forced them too. AIDS in Africa? It's America's fault. It's
1 a CIA plot
2 we don't spend enough money on AIDS research
3 we don't give them enough money to combat it.
We're all gonna die by global warming? It's America's fault for driveing (the EVIL) SUV's.
This is a practice straight out of Marxism. The Marxist would compare their utopian society to reality, which of course would fall short and demand instant change.
