Letter from R. C. Treweeks, Defense Intelligence Staff, to Alan C. Goodison, Eastern Department of the Foreign Office

In a letter to Arthur Kellas, counselor at the British Embassy in Tel Aviv, Alan Goodison of the Foreign Office's Eastern Department disclosed the Argentine-Israel uranium deal, which involved the transfer of 80-100 tons over 33 months. Since evidence suggested that Israel had facilities for plutonium separation, they estimated that there would be enough plutonium for a weapon within 20 months; however, Goodison had no proof that the Israelis planned to produce a nuclear weapon, only that they had the capability to do so. Minutes are attached.

In response to Alan Goodison's April 29 letter, which referred to evidence for an Israeli plutonium separation facility, Arthur Kellas, counselor to the British Embassy in Tel Aviv, states that the British Embassy had “not seen such evidence [for a separation facility] and should be grateful to know what it is."
