From what I know it's not such a strange idea and if perfectly fits into the field of counter-information.
I have read that the Soviets were real experts. I can actually still remember small scientific articles on magazines and newspapers claiming Soviet scientists to have discovered anything from dead rays to cold fusion... these articles were said to have been "planted" by the Soviets for several purposes, one of them trying to led the Western powers to waste money on useless research.
This hypothesis has in fact been a quite popular one and it make a lot of sense too.
And you can also recall the whole UFO thingy which after de-classifying the documents showed that the whole alien fairytale was encouraged by the Air Force as a measure of counter-intelligence quite convenient to cover up some secret projects like a giant surveillance balloon or (then) ultra-modern airplanes including an atomic powered one... yes, I agree, the balloon (Project Mogul) isn't quite as sexy as hot alien chicks from Venus but back then there were no spy sats and a huge helium filled condom packet with telemetry was the closed you could get back then to find out if Ivan had had a bad day and decided to press the Red Button.
