#3-034 Memorandum for the Under Secretary of State [Welles] December 31, 1941 [Washington, D.C.] Secret Subject: Japanese Intentions to wreck Rio Conferences and the Good Neighbor Policy.1 1. For your convenience there has been prepared the attached summary of a series of communications between the Japanese Foreign Office and its officials in the field. I wished this data brought to your attention before your departure for Rio. 2. The communications have been sent during the past three weeks. A file of the original messages are on hand in the State Department. They furnish conclusive evidence that the Japanese are effectively engaged in wrecking the Good Neighbor Policy in Latin America in every possible manner. A careful perusal of Nos. 26620, 26682, 26751 and 26769 will give the details of their immediate project for torpedoing the approaching conference at Rio de Janeiro. A further dispatch of importance is one which outlines a plan to enlist the aid of the Vatican. (No. 26856) 3. The War Department has received, in addition to this intelligence, confirmatory information from many other sources as to the close collaboration between the three Axis powers in Latin America. All three are busily spreading propaganda injurious to the U. S. A. and exploiting to the utmost the news of their recent successes. 4. Particularly active centers of Japanese activities are now located in Lima, Santiago and Buenos Aires. The movements of Colonel Waki [Wachi], former Military Attache in Washington, in his recent travels in Latin America, are most significant in this regard. It seems evident that he is establishing a reliable and intensive intelligence and propaganda organization throughout Latin America.2 5. I am strongly of the opinion that the situation in South America is grave and immediate. I am particularly concerned over the present hazard to which our communications to the Near and Far East are exposed in Brazil. 6. I suggest that it might be dangerous to take these papers out of the United States. Their loss would destroy our most important access to Axis plans. Document Copy Text Source: George C. Marshall Papers, Pentagon Office Collection, Selected Materials, George C. Marshall Research Library, Lexington, Virginia. Document Format: Typed memorandum. 1. At this time Under Secretary of State Sumner Welles was engaged in organizing the Third Consultative Meeting of the American Foreign Ministers, scheduled to take place in Rio de Janeiro, January 15–28. 2. Perhaps as a result of this memorandum, on January 1 Welles observed in a message to the U.S. ambassador in Uruguay that he should tell that government that the United States believed that "the continued functioning of the Axis diplomatic and consular establishments in the Western Hemisphere creates under present conditions the gravest danger to the security of all of the republics and to the ability of the American governments to take necessary and adequate measures of defense. It is well known that Axis consular officials are reporting continuously on the movements of ships and on defense preparations. It is likewise notorious that the Axis diplomatic missions are engaging in every type of subversive activity and are intervening in the most blatant manner in the purely internal and domestic concerns of the countries where they are stationed in order to foment internal discord and to promote the existence of conditions which are in the highest degree prejudicial to the security of us all."
