 As the 1960s brought left-wing guerrilla activity to Argentina, Genta was recognized as one of the ideologues behind ever-more violent far right groups such as Tacuara.Ironically, some of Tacuara's young recruits would later form the core of the (allegedly left-wing Peronist) Montoneros movement.The armed struggle degenerated into the so-called dirty war, which claimed thousands of lives and cast a heavy shadow over Argentine politics well into the 21st century.
