So I wrote this piece about the conviction of the former military dictator of Argentina, on charges of crimes against humanity committed during Argentina's so called "Dirty War" from 1976 -1983. The Military sought to eliminate leftist (Socialism and Communist) movements and those who supported them. While these two factions fought it out, eventually the Military became to target not just active leftist militants, but also any and all that were deemed "subversive". Over the course of only years, nearly 30,000 people "Disappeared" never to be seen again.
