This telegram, sent through the special âRoger channelâ used for intelligence subjects, refers to an earlier embassy message, number 2319, dated November 12, 1963, which has yet to be found at the US at the National Archives. That telegram may refer to French actions to halt the supply of uranium to Israel which were alluded to indirectly in this message. Jacques Martin, a French Foreign Ministry expert on nuclear matters, told US embassy officials that the Israelis, who had refused to sign an agreement to purchase uranium exclusively from France, were looking for other sources, most likely Belgium and Argentina.
