He recommended that the Commission adopt this paper, with such revisions as it wished, as a basis for discussion by the Chairman with the Spccia 1 Committee of the National Security Council. The Commission discussed extensively the statement of the AEC position contained in AIZC 190/46 and the proposed revision contained in Mr” ~:urraY’s memorandum to the Commissioners dated lhlay 16, 1951 (copy on file in the Cfficc of the Secretary), It was pointed out that the basic policy decision to be made by the President and National Security Council was whether partnership between the UK and Canada and the United States should be full or limited, and that the ambiguities and limitations in the Department of Defense position which had been discussed with the XULC at the conference on May 7, 1951, might better be clarified following any such policy decision. Mr. Boycr said that the question had arisen of a second conference of representatives of the UK, Canada, and the U.S. on security standards and practices, on the lines of the one held in Washington June 19, 1950 (AEC 302/10). Mr., Glennan pointed out that scheduling of such a conference while establishment of an Executive Branch position on relations with the UK and Canada was underway would bc a us cful demonstration of the Commission’s concern for maintenance of security under an extended program of cooperation.
