Mr. Strauss observed that the recent Presidential decision on custody of thermonuclear weapons would partially solve the problem of transmitting information on these weapons to the U, K. (See minutes of the Executive Session of Meeting 1118.) He suggested that Colonel Starbird discuss with General Loper the problems which the DOD would encounter if the Commission judgment on the thermonuclear weapons information is deferred.
