Having risen to power on an anti-Marxist agenda, Pinochet found common cause with the military dictatorships of Bolivia, Brazil, Paraguay, Uruguay, and later, Argentina. The six countries eventually formulated a plan known as Operation Condor, in which the security forces of participating states would target active left-wing militants, guerrillas fighters, and their alleged sympathizers in the allied countries. Pinochet's government received tacit approval and material support from the United States. The exact nature and extent of this support is disputed. ("See" U.S. role in 1973 Coup, U.S. intervention in Chile and Operation Condor for more details.) It is known, however, that the American Secretary of State at the time, Henry Kissinger, practiced a policy of supporting coups in nations which the United States viewed as leaning toward Communism.
