There is a ton of info thats not contaminated by state dept propaganda on this on here, it is undeniable that the CPK is responsible for a lot of mismanagement and attrocities during their rule of Cambodia although the 110.000 tons of bombs the US dropped didnt help the economic situation of Cambodia.

Hundreds of thousands of the deaths attributed to pol pot and the CPK should more correctly been attributed to said bombing and the starvation and instability that came with it. The total figure is also vastly exaggerated with very flimsy sources. Though again, pol pot emptying the cities and abolishing money did worsen the situation.

The CPK was also extremely brutal and extremist in their ways where even their fellow members were tortured and killed due to paranoia of western and revisionist subversion. Official documents are very rare and hard to find due to the peasant anti intellectual nature of the khmer rogue and the destruction of said documents following the invasion. Surviving CPK members have not writen down their own experience that we can find.

After Vietnam overthrew pol pot, Cambodia became a quasi colony of Vietnam which halted their development (though not as much as a continuing pol pot regime rule would have). Even now after the withdrawal of occupying Vietnamese forces, Cambodia and its resources is still frequently exploited by Vietnamese companies. This relationship of Vietnam and Cambodia is very much influenced by the history of Vietnamese invasions and attempted conquests of cambodia.

Basically yes, the killing fields are real and khmer rogue were brutal. But are also very exaggerated by the west. But also the Vietnamese invasion and occupation of Cambodia is not really a wholesome 100 real communism vs fake cia communism moment many leftists make it to be.
