 While Yuon, Nim, and Samphan had a long experience of being castigated and humiliated by Sihanouk during their years as "Sangkum" deputies and earlier, Sihanouk had a particular personal dislike for Ieng Sary, who in 1971 was assigned from Hanoi with the express mission of keeping Sihanouk under control.Sihanouk repeatedly (and quite incorrectly) accused him of being a North Vietnamese agent, and forced Sary to sit through "risque" films obtained from the French embassy, revelling in his obvious discomfort.Sary, for his part, attempted to spread dissention in the royal entourage, and between Sihanouk and Penn Nouth.
