> Didn't Argentina have a bunch of folks simply go missing?
Argentina, under Juan Peron, had a double whammy of the right wing death squads (take notes, anon's) and the "disappearances" which came a little bit later.
About 1,500+/- were accounted for by the death squads, and perhaps as many as 30,000 children and young adults were "dissapeared".
