Cambodian genocide denial

Denial of the Cambodian genocide is the belief expressed by some academics that early claims of atrocities committed by the Khmer Rouge government (1975–1979) in Cambodia were exaggerated. Many scholars of Cambodia and intellectuals opposed to the US involvement in the Vietnam War denied or minimized reports of human rights abuses of the Khmer Rouge, characterizing contrary reports as "tales told by refugees" and US propaganda.
