The Khmer Rouge’s reign in Cambodia was devastatingly brutal and merciless, it also ultimately resulted in a tragic genocide that took the lives of millions of innocents, from political opponents to Buddhist monks who faced incomprehensibly cruel executions, daunting forced labor, harsh starvation, and painful deaths from diseases and infections. Without a doubt, the root of this evil and the complete destruction of a beautiful country and peoples was the Communist ideology. In Cambodia, it seeped into the minds of the Khmer Rouge who sought to create a radically classless society by any means necessary and at the extent of anyone; everyone was deemed unimportant and easily replaceable under the Angkor system. While some might also try to make the argument that these atrocities are a reflection of the Khmer Rogue's revolution and personality alone, in the end, it's hard to argue that communism didn't play a center role when the Khmer Rouge’s extreme interpretation and brutal execution of millions was a result of the communist ideology that led to such widespread suffering.
Fundamentally, the Khmer Rouge's vision was built on the deeply flawed and unrealistic belief that all aspects of modernity, education, class and foreign influence was inherently evil and needed to be completely eradicated from Cambodian society. Sok Udom Deth emphasizes the explicitly when he wrote in The Rise and Fall of Democratic Kampuchea (2009), how the Khmer Rouge viewed intellectuals and the wealthy as enemies of the revolution and the country specifically. They wrongfully believed that the only way to a pure and united Cambodia was through extreme forced labor in the fields and re-education in camps scattered throughout the countryside. This radical belief sought to break away from any forms of tradition and progress that did not perfectly align with the Khmer Rogue's concept of communism.
The Khmer Rouge leadership, especially under cruel communist leader Pol Pot, demonstrated extreme paranoia that manifested into authoritarianism that turned against and prosecuted its own party members. This was an unfortunate result of the Khmer Rogue belief that “tt is better to kill ten innocent people than to let one guilty person go free.” Mass executions were usually resulted in thousands being tortured and then eventually killed, which was not a result of communist principles alone but of the dictatorship that derived from communist ideology and went completely unchecked for years. As Samantha Power brilliantly emphasizes in her articles A Problem from Hell: America in the Age of Genocide (Power, 2002) (Cambodia: The Unknowable Unknown and Wishful Thinking), the Khmer Rouge were prone to ruling in complete secret as paranoia infused every aspect of their lives and every action they ever took, while the Western world looked on, choosing to remain unaware and unwilling to act despite the undeniable evidence of atrocities. Their secrecy combined with the international community's reluctance to intervene ultimately allowed them to continue inflicting brutal atrocities and horrors unfolded without any pressure to stop or accountability.
This ultimately leads to the broader question we must all ask regarding whether or not brutality and violence is inherent to communism. With historical examples ranging from Joseph Stalin’s Soviet Union to Mao Zedong’s Chinese Communist Party to Ho Chi Minh's eventual communism state, the pattern is undeniable and demonstrates that communist regimes have always been prone to widespread human rights abuses while also being careful with the importance in distinguishing an ideology from its out of touch execution. Communism, like any political belief or system, can be interpreted and applied in many different ways ways. However, communism's disregard for class and education, its anger at intellectuals and the wealthy, and the blame it places on all things foreign or class related allows pure evil and hatred to fester and grow, ultimately resulting in the brutal communist regimes we're so prone to seeing.
Ultimately, the tragedy of Cambodia under the Khmer Rouge underscores the danger of radical ideological extremism combined with authoritarianism and dictatorships. It wasn’t just communism that led to the Khmer Rogue's brutal regime and leadership but communism did play a major role in how said leadership rejected tradition and humanity in pursuit of an impossible to achieve society that has never and will never exist.
