In the mid-1970s, the governments of the southern cone of South America—Brazil, Chile, Argentina, Paraguay, Bolivia, and Uruguay—had several things in common. They were ruled by conservative regimes, either dictators or military juntas, and they had a growing problem with opposition forces and dissidents. They, therefore, established Operation Condor, a collaborative effort to round up and kill or otherwise silence their enemies.
By the time it ended, thousands were dead or missing and the trust of South Americans in their leaders was forever shattered. Although new facts come out occasionally and some of the worst perpetrators have been brought to justice, there are still many questions about this sinister operation and those behind it.
