I'm thinking of the Khmer student group in Paris, and its relation with the later government apparatus of "Democratic" Kampuchea. This group included Pol Pot, Thieu Samphan, Ieng Sary and Ieng Thirith, and Hou Yuon.
Were these students influenced by their tutors at the time? IIRC, French academia has long been a hub for radical left-wing thought - cf Georges Boudarel, Mai 68. Who would have been teaching the future Khmer Rouge? What were they studying? What causal relationship, if any, exists between their French education and the horror they unleashed upon Cambodia when they gained power?
This is an interesting question, I was hoping someone qualified would answer it when you posted it again.
