Operation Opera (Hebrew: אופרה‎), also known as Operation Babylon, was a surprise Israeli air strike carried out on 7 June 1981, which destroyed an Iraqi nuclear reactor under construction 17 kilometers (10.5 miles) southeast of Baghdad. The operation came after Iran's unsuccessful Operation Scorch Sword operation had caused minor damage to the same nuclear facility the previous year, the damage having been subsequently repaired by French technicians. Operation Opera, and related Israeli government statements following it, established the Begin Doctrine, which explicitly stated the strike was not an anomaly, but instead “a precedent for every future government in Israel.” Israel's counter-proliferation preventive strike added another dimension to their existing policy of deliberate ambiguity, as it related to the nuclear capability of other states in the region.
