No, I haven't seen it yet. Does it deal with the Julius and Ethel Rosenberg spy case, since it seems to me that that was the biggest spy case in the U.S..?
If memory serves, the documents filched by the Rosenbergs aided the Soviet Union in getting the atomic bomb and catching up to the U.S. in nuclear technology, such that the cold war was the only option that was rational and civic. Anthing else would have supported the insanity of mutual destruction.
