I do not think the moonlanding was faked and I really like that argument but still I do wonder what were the real level of intel (and level of confidence they had in that Intel) each of the two world powers had on each other at the time when the USSR existed. Also it could have happened that the USSR decide to propagate that the moon landing was fake for propaganda's purposes.
