Nuclear Proliferation Middle-East

The Harriman-Komer mission in 1965 led to Israeli agreement not to be the first to introduce nuclear weapons into the area and U.S. agreement to sell Israel tanks equivalent to those sold to Jordan, as well as combat aircraft. The United States and Jordan soon reached agreement on a U.S. sale of tanks and other equipment.

President Johnson and Secretary of State Rusk were particularly concerned about the threat of nuclear proliferation in the Middle East, and Rusk warned Israel that it would “lose U.S. support” if it developed nuclear weapons. The administration probed the possibility of an indirect arrangement to prevent the introduction of advanced weapons by Israel and the United Arab Republic.

The United States first became aware of Dimona’s existence after U-2 overflights in 1958 captured the facility’s construction, but it was not identified as a nuclear site until two years later. The complex was variously explained as a textile plant, an agricultural station, and a metallurgical research facility, until David Ben-Gurion stated in December 1960 that Dimona complex was a nuclear research center built for “peaceful purposes.”

There followed two decades in which the United States, through a combination of benign neglect, erroneous analysis, and successful Israeli deception, failed to discern first the details of Israel’s nuclear program. As early as 8 December 1960, the CIA issued a report outlining Dimona’s implications for nuclear proliferation, and the CIA station in Tel Aviv had determined by the mid-1960s that the Israeli nuclear weapons program was an established and irreversible fact.

United States inspectors visited Dimona seven times during the 1960s, but they were unable to obtain an accurate picture of the activities carried out there, largely due to tight Israeli control over the timing and agenda of the visits. The Israelis went so far as to install false control room panels and to brick over elevators and hallways that accessed certain areas of the facility. The inspectors were able to report that there was no clear scientific research or civilian nuclear power program justifying such a large reactor – circumstantial evidence of the Israeli bomb program – but found no evidence of “weapons related activities” such as the existence of a plutonium reprocessing plant.

Although the United States government did not encourage or approve of the Israeli nuclear program, it also did nothing to stop it. Walworth Barbour, US ambassador to Israel from 1961-73, the bomb program’s crucial years, primarily saw his job as being to insulate the President from facts which might compel him to act on the nuclear issue, alledgedly saying at one point that “The President did not send me there to give him problems. He does not want to be told any bad news.” After the 1967 war, Barbour even put a stop to military attachés’ intelligence collection efforts around Dimona. Even when Barbour did authorize forwarding information, as he did in 1966 when embassy staff learned that Israel was beginning to put nuclear warheads in missiles, the message seemed to disappear into the bureaucracy and was never acted upon.
