The so-called Colonels’ coup of April 21, 1967, was a major event in the history of the Cold War, ushering in a seven-year period of military rule in Greece. In the wake of the coup, some eight thousand people affiliated with the Communist Party were rounded up, and Greece became yet another country where the fear of Communism led the United States into alliance with a repressive right-wing authoritarian regime. In military coups in some other countries, it is known that the CIA and other agencies of the U.S. government played an active role in encouraging and facilitating the takeover. The Colonels’ coup, however, came as a surprise to the United States (which was expecting a Generals’ coup instead). Yet the U.S. government accepted it after the fact, despite internal disputes within policymaking circles about the wisdom of accommodating the upstart Papadopoulos regime. Among the dissenters was Robert Keeley, then serving in the U.S. Embassy in Greece. This is his insider’s account of how U.S. policy was formulated, debated, and implemented during the critical years 1966 to 1969 in Greek-U.S. relations.
