Argentina’s annual March 24 commemoration of the 1976 military coup that ushered in the country’s violent right-wing dictatorship is acquiring new urgency under the government of President Javier Milei. The far-right economist and his vice president, who hails from a prominent military family with an uncle accused of crimes against humanity, are challenging how Argentina understands the darkest chapter in its modern history. Human rights groups, which estimate that 30,000 people were killed or forcibly disappeared during the 1976-83 dictatorship that waged the “dirty war,” increasingly fear the country’s iconic rallying cry, “Nunca Mas,” or “Never Again,” has come under new threats.
