411550 February 27, 1956 MEMORANDUM TO MR. SUBJECT: STRAUSS DEMONSTRATION CLEAW SHOT IN HARDTACK John McGruder has told you that at yesterday's Commission meeting the four Commissioners split 2 - 2, Libby and Vance versus Graham and Floberg against and for the demon- stration Clean Shot in HARDTACK. The fact that you voted YES by proxy did not persuade Dr. Libby to consider the matter carried by majority vote. The subject will therefore rise again Friday when I expect it to be carried by a 3 - 2 vote, or possibly 4 - 1, if you are present and I can change lft. Vance's views meanwnile. Time in which to organize the observer and technical programs is critically short. The laboratories, particularly Los Alamos, and most of the Division of liilitary Application, consider the demonstration a waste of time. If this is reflected in visiblc evidence before the observers, results for this country inay be adverse rather than favorable. I therefore strongly recomnend that you make clear to the General ilanager ard General Starbird that you wish the critical nature of this program made clear to the entire organization, and that it be organized and conducted with the sreatest care. if further recommend that Dr. Lawrence or Dr. Teller, or both, take an active part in briefing the observers and in seneral supervision of the treatment they receive. I believe this a matter of utmost importance, de- serving of your very close attention throughout. ols . 320 U.S. ATOMIC EEs COMMISS*C*' i Ne we hee | Coll. ciion Box 1 ‘ _! MHigter. —— rae .
