After he was overthrown, the United States continued to recognize Pol Pot as the legitimate leader of Cambodia at the United Nations.[3] Between 1980 and 1986, Pol Pot’s exiled forces received $85 million in funding from the United States and their operations were run by 50 CIA agents in Thailand. U.S. national security advisor Zbigniew Brzezinski also encouraged China to support Pol Pot. In August 1990, a former member of the U.S. special forces disclosed that he had been ordered to destroy documents showing that the U.S. was supplying Pol Pot with munitions from Thailand.[1]
The United States (U.S.) voted for the Khmer Rouge and the Khmer Rouge-dominated Coalition Government of Democratic Kampuchea (CGDK) to retain Cambodia’s United Nations (UN) seat until as late as 1993
I know this is basically a meme, but I wouldn’t be surprised if Pol Pot had connections to the CIA.
