Сон Сен
The Khmer Rouge leadership was almost completely unknown by the public. They were referred to by their fellow countrymen as "peap prey" – the forest army. Previously, the very existence of the communist party as a component of GRUNK had been hidden. Within the "liberated zones" it was simply referred to as "Angka" – the organization. During 1973, the communist party fell under the control of its most fanatical members, Pol Pot and Son Sen, who believed that "Cambodia was to go through a total social revolution and that everything that had preceded it was anathema and must be destroyed."
