TOP SECRET

infiltration by Communists and Soviet agents into U.S. Government during the 1940's when the Democrats were in power. At the same time, the Democrats would probably strike back by claiming that the FBI withheld this information from the proper officials during the Democratic administration and at the same time would salvage what credit they could by claiming that the messages were intercepted and deciphered during the course of their administration and under their guidance. The Bureau would be right in the middle.

E. International Implications

The Russians would undoubtedly scream that the U.S. had been expending money and manpower on intercepting and breaking the Russian code during the time the two countries were allied against a common enemy. Its propaganda machine would work overtime proving that this was evidence that the U.S. never acted in good faith during the war. Also, while no written record has been located in Bureau files to verify this it has been stated by NSA officials that during the war Soviet diplomats in the U.S. were granted permission to use Army radio facilities at the Pentagon to send messages to Moscow. It has been stated that President Roosevelt granted this permission and accompanied it with the promise to the Soviets that their messages would not be intercepted or interfered with by U.S. authorities. Here, again, the Soviets would vilify the U.S. as an unfaithful ally and false friend.

F. Effects on Pending Cases  

The Bureau is currently investigating about 100 cases on individuals either mentioned in   traffic or having some connection therewith. In addition, some of the subjects in the Mocase are mentioned in the   traffic. The public revelation of our knowledge of this traffic and the individuals involved therein probably would cause some of these individuals who may still be operating for the Soviets to discontinue their activities and possibly disappear. The effects on these pending cases would be difficult to assess at this time.
