I just finished watching The Killing Fields in a class about the Vietnam war. I was wondering what happened to those children who were indoctrinated into Pol Pot's year zero thinking and participated in killings, spying on their own family, etc. Were they ever integrated back into normal society? How did they cope with the complete severance from their families at such a young age?

I hope this isn't treading too closely to modern events, but since the majority of the genocide happened in the 70s and Vietnam held control of the country by the 80s, I thought it was safe to ask.
