Bamford (The Puzzle Palace) suggests that no major Soviet or American cipher has been cryptanalyzed since the early 70s or so. Ciphers are chipped at by theft of keys by spies (The Falcon and the Snowman) or military action (Seizing the Enigma). Also, you have to ask yourself, would the NSA reveal its ability to break GOST traffic? (I think it was Seymour Hersh who made the claim that the Bush administration gave Yeltsin real time breaks* of Generals plotting against him in the '92 coup attempt. In evaluating this claim, remember Bush ran the CIA for several years.) (*It also might be that the messages were not protected by GOST, were obtained by bugging in a room, or other nefarious means, as I'm sure the NSA would attest if it came out that messages were actually passed.)
