Persecution and extermination of people linked to groups considered Marxist (criteria that was applied in a very broad spectrum that included organizations such as ERP or Montoneros to social democratic groups, such as the Radical Civic Union)
The Argentine Anticommunist Alliance (Spanish: Alianza Anticomunista Argentina, usually known as Triple A or AAA) was an Argentine Peronist and fascist political terrorist group operated by a sector of the Federal Police and the Argentine Armed Forces, linked with the anticommunist lodge Propaganda Due, that killed artists, priests, intellectuals, leftist politicians, students, historians and union members, as well as issuing threats and carrying out extrajudicial killings and forced disappearances during the presidencies of Juan Perón and Isabel Perón between 1973 and 1976.[11][12][13][14] The group was responsible for the disappearance and death of between 700 and 1100 people.[15][16][17]
The Triple A was secretly led by José López Rega, Minister of Social Welfare and personal secretary of Juan Perón. Rodolfo Almirón, arrested in Spain in 2006, was alleged to be his chief operating officer of the group, and was officially head of López Rega's and Isabel Perón's personal security. He was extradited from Spain in 2006 and prosecuted; he died in jail in June 2009. SIDE agent Anibal Gordon was another important member of the Triple A, although he always denied it. He was tried in Argentina in 1985 after the restoration of democracy and convicted in October 1986. Gordon died in prison of lung cancer the next year.[18]
In 2006, Argentine Judge Norberto Oyarbide ruled the Triple A had committed "crimes against humanity," which meant their crimes were exempt from statutes of limitations. Suspects can be prosecuted for actions committed in the 1970s and early 1980s.
