While revealing new details about one of the most famed CIA operations of all times — the spiriting out of six American diplomats who escaped the 1979 U.S. Embassy seizure in Iran — the intelligence agency for the first time has acknowledged something else as well. The CIA now officially describes the 1953 coup it backed in Iran that overthrew its prime minister and cemented the rule of Shah Mohammad Reza Pahlavi as undemocratic. While other American officials have made similar remarks in the past, the acknowledgment by the CIA in a podcast about the agency’s history comes as much of its official history of the coup still remains classified 70 years after the putsch.
