  The "Dirty War" (Spanish: Guerra Sucia) was part of Operation Condor, which included the participation of other right-wing dictatorships in the Southern Cone. The Dirty War involved state terrorism in Argentina and elsewhere in the Southern Cone against political dissidents, with military and security forces employing urban and rural violence against left-wing guerrillas, political dissidents, and anyone believed to be associated with socialism or somehow contrary to the neoliberal economic policies of the regime. Victims of the violence in Argentina alone included an estimated 15,000 to 30,000 left-wing activists and militants, including trade unionists, students, journalists, Marxists, Peronist guerrillas, and alleged sympathizers. Most of the victims were casualties of state terrorism. The opposing guerrillas' victims numbered nearly 500–540 military and police officials and up to 230 civilians. Argentina received technical support and military aid from the United States government during the Johnson, Nixon, Ford, Carter, and Reagan administrations.
  
  The exact chronology of the repression is still debated, yet the roots of the long political war may have started in 1969 when trade unionists were targeted for assassination by Peronist and Marxist paramilitaries. Individual cases of state-sponsored terrorism against Peronism and the left can be traced back even further to the Bombing of Plaza de Mayo in 1955. The Trelew massacre of 1972, the actions of the Argentine Anticommunist Alliance commencing in 1973, and Isabel Perón 's "annihilation decrees" against left-wing guerrillas during Operativo Independencia (Operation Independence) in 1975, are also possible events signaling the beginning of the Dirty War.
  
  Onganía shut down Congress, banned all political parties, and dismantled student and worker unions. In 1969, popular discontent led to two massive protests: the Cordobazo and the Rosariazo. The terrorist guerrilla organization Montoneros kidnapped and executed Aramburu. The newly chosen head of government, Alejandro Agustín Lanusse, seeking to ease the growing political pressure, allowed Héctor José Cámpora to become the Peronist candidate instead of Perón. Cámpora won the March 1973 election, issued pardons for condemned guerrilla members, and then secured Perón's return from his exile in Spain.
  
  On the day Perón returned to Argentina, the clash between Peronist internal factions— right-wing union leaders and left-wing youth from the Montoneros—resulted in the Ezeiza Massacre. Overwhelmed by political violence, Cámpora resigned and Perón won the following September 1973 election with his third wife Isabel as vice-president. He expelled Montoneros from the party and they became once again a clandestine organization. José López Rega organized the Argentine Anticommunist Alliance (AAA) to fight against them and the People's Revolutionary Army (ERP).
  
  Perón died in July 1974 and was succeeded by his wife, who signed a secret decree empowering the military and the police to "annihilate" the left-wing subversion, stopping ERP's attempt to start a rural insurgence in Tucumán province. Isabel Perón was ousted one year later by a junta of the combined armed forces, led by army general Jorge Rafael Videla. They initiated the National Reorganization Process, often shortened to Proceso.
  
  The Proceso shut down Congress, removed the judges on the Supreme Court, banned political parties and unions, and resorted to employing the forced disappearance of suspected guerrilla members including individuals suspected of being associated with the left-wing. By the end of 1976, the Montoneros had lost nearly 2,000 members and by 1977, the ERP was completely subdued. Nevertheless, the severely weakened Montoneros launched a counterattack in 1979, which was quickly put down, effectively ending the guerrilla threat and securing the junta's position in power.
  
  In March 1982, an Argentine force took control of the British territory of South Georgia and, on 2 April, Argentina invaded the Falkland Islands. The United Kingdom dispatched a task force to regain possession. Argentina surrendered on 14 June and its forces were taken home. Street riots in Buenos Aires followed the humiliating defeat and the military leadership stood down. Reynaldo Bignone replaced Galtieri and began to organize the transition to democratic governance.
