I'm not sure where this bizarre revision of history comes from. The "West", dominated by the US for the past century, has installed plenty of brutal dictators and military regimes, mostly when countries ignored the US to go left, not right.
See Iran, Syria, a good fraction of Latin America including Cuba, Chile, Venezuela, Nicaragua, Honduras, along with Korea and Vietnam.
Western governments, including Reagan, Nixon, and Thatcher ignored and even actively supported SA's apartheid government for decades.

Well, sure, because the Western anti-Communist support that propped it up wouldn't have existed, so there’d have been nothing to protest or boycott. The US and other Western allies didn't support it and (at a minimum) turn a blind eye to Israel transferring nuclear weapons technology to South Africa independently of it's anti-Communisr orientation.
You are confusing support from a few academics and socialist groups with foreign policy.
As it turns out, Noam Chomsky writing nasty op-eds that don't get published in the New York Times has less of an impact then what side of the bed the Secretary of State woke up on.
