The United States first became aware of Dimona’s existence after U-2overflights 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.
