Nearly 40 years after suffering the totalitarian nightmare of the Khmer Rouge, victims of Cambodia’s horrific history were granted a small measure of justice on Friday. An international criminal tribunal convicted two aging former Khmer Rouge leaders in a historic ruling that for the first time legally defines the regime’s crimes as genocide. The defendants, Nuon Chea, 92, and Khieu Samphan, 87, are among the last surviving chieftains of the Khmer Rouge, a brutal regime that decimated Cambodia from 1975-1979 in an effort to recreate a utopian agrarian society.
