Political map of South American nations 01 March 1979 (Operation Condor): In response to the guerrilla movements of the 1960s and 1970s, the right-wing governments of southern South America organized Operation Condor (Operation Condor), covertly agreeing to cooperate in the suppression of left-wing movements across the region. They were supported in this by the United States, which approved of their hostility to Communism (Cold War), but their main interest lay in removing any opposition to their regimes.
