Newly declassified memos reveal President Richard Nixon discussed with Brazil’s president a cooperative effort to overthrow the governments of Salvador Allende of Chile and Fidel Castro of Cuba. At a meeting in the Oval Office on December 9, 1971, Nixon said he was willing to offer Brazil the assistance, monetary or otherwise, it might need to rid South America of leftist governments. Nixon said the US and Brazil “must try and prevent new Allendes and Castros and try where possible to reverse these trends.” Twenty months later, on September 11, 1973, Allende was overthrown in a US-backed coup led by General Augusto Pinochet.
