Probably a lot of propaganda in this. But don’t forget, that before WWII, we denigrated the ability of the Japanese to fight us. In reality, they came up with a superior fighter (Zero),
more modern ships, much better torpedos, etc.—while we were stuck with outmoded and sometimes non-functioning weapons systems.
(And, they captured Singapore, which was thought to be unconquerable.)
Maybe the Russians aren’t 10 feet tall, but it is best to assume that they aren’t midgets, either; and be prepared to meet them.
My guess is that if the Russkies have it we have it also. We probably just keep it quiet.
