Operation Opera

Operation Opera (Hebrew: מִבְצָע אוֹפֵּרָה), also known as Operation Babylon, was a surprise airstrike conducted by the Israeli Air Force on 7 June 1981, which destroyed an unfinished Iraqi nuclear reactor located 17 kilometres (11 miles) southeast of Baghdad, Iraq. The Israeli operation came a year after the Islamic Republic of Iran Air Force had caused minor damage to the same nuclear facility in Operation Scorch Sword, with 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 its existing policy of deliberate ambiguity, as it related to the nuclear weapons capability of other states in the region.

In 1976, Iraq purchased an Osiris-class nuclear reactor from France. While Iraq and France maintained that the reactor, named Osirak by the French, was intended for peaceful scientific research, the Israelis viewed the reactor with suspicion, believing it was designed to produce nuclear weapons that could escalate the ongoing Arab–Israeli conflict. On 7 June 1981, a flight of Israeli Air Force F-16A fighter aircraft, with an escort of F-15As, bombed the Osirak reactor deep inside Iraq. Israel called the operation an act of self-defense, saying that the reactor had "less than a month to go" before "it might have become critical." The airstrike reportedly killed ten Iraqi soldiers and one French civilian. The attack took place about three weeks before the 1981 Israeli legislative elections for the Knesset.

At the time of its occurrence, the attack was met with sharp international criticism, including in the United States, and Israel was rebuked by the United Nations Security Council and General Assembly in two separate resolutions. Media reactions were also negative: "Israel's sneak attack ... was an act of inexcusable and short-sighted aggression", wrote The New York Times, while the Los Angeles Times called it "state-sponsored terrorism". The destruction of Iraq's Osirak reactor has been cited as an example of a preventive strike in contemporary scholarship on international law. The efficacy of the attack is debated by historians, who acknowledge that it brought Iraq back from the brink of nuclear capability but drove its weapons program underground and cemented Iraqi president Saddam Hussein's future ambitions for acquiring nuclear weapons.
