This memorandum from Executive Secretary Benjamin Read of the Department of State to National Security Advisor McGeorge Bundy provides a valuable chronology of the US discovery of the nuclear reactor project at Dimona and the pledges made by the Israelis in response to requests from the United States. Included in the chronology is an item about a meeting on 25 May 1963 where senior French diplomat Charles Lucet told CIA director John McCone that even though the French had helped build the Dimona reactor, “there might be a nuclear complex not known the French.” Lucet further stated that the Israelis had tried to purchase “safeguard-free” uranium from Gabon but that the French government stopped the sale through preemptive purchases.
