UNITED STATES 111553 ATOMIC ENERGY COMMISSION WASHINGTON 25,D. C. Nhe eet gran January 4, 1955 MEMORANDUM FOR CHAIRMAN LEWIS L. STRAUSS Dear Lewis: SUBJECT: U. N. Observers at Operation TEAPOT You will recall that in a memorandum to you dated October 12, 1953, I recommended that U.N. observers be invited to witness a test shot in connection with Operation CASTLE. I continued to urge an uncleared observer program in subsequent memoranda. You are also familiar with my letter to The President on this subject. Operation TEAPOT presents us with a new opportunity for an uncleared observer program. I recommend that such a program be approved and specifically that U. N. observers be invited. The arguments in favor of such a course remain com- pelling. It is remotely possible, though unlikely, that the Soviets would counter with a similar invitation. Certainly this would be welcomed as the preliminary to any negotiations looking to possible eventual curtailment of the weapons race. In any event a considerable propaganda advantage would accrue to the United States. As you know, approval is now being sought for observers at TEAPOT from Canada and the NATO organization. With adequate safeguards, I am generally in favor of granting such approval. At the same time, according such permission without providing for U. N. representation would, in my opinion, be a grave mistake. I trust that the Commission will approve the Canadian and NATO observers and will also provide for U. N. representation, all, of course, with adequate safeguards. LEM: Thomas E. Murray te ce: Dr. Libby K. D. Nichols W. B.
