Oh, I'm sure Cambodians are happy that America didn't invade it and the same intellectuals that blamed US for Vietnam praised Pol Pot as champion of peace and enlightened socialist leadership.
The Cambodians were even happier when the US dropped more ordinance(specifically cluster munitions) on their country than was dropped by the allies on Japan during WWII.
Unexploded ordinance dropped by the US on Cambodia and Laos has rendered large swaths of land unproductive, and still leads to hundreds of deaths and injuries every year to this very day. Cambodia has an entire cottage industry devoted to recycling and neutralising American bombs.
It is almost certain that the US helped the coup in vietnam and the insured that it succeeds. It was the North Vietnam Communist army that stopped the insane regime in Cambodia.
That communist and leftist had widly positive views of any regime that called itself 'communist' or 'socialist' is well known. Even if it is today often ignored.
