I get the arguments for this idea. Why did USSR play along? They (claim they) had all the same transmissions and everything else we did, and they called us to congratulate us. I guess they could have just made a wild guess, but it seems more likely that they ... observed us land on the moon before calling us to congratulate us on landing on the moon.
Likewise we observed all their unmanned flights, and our records for all this agree.
I suppose many normies fall for the us vs them of the cold war and never consider the fact that there are always hidden agreements and facades. Things are not what they seem to be.
It is for this very reason that big hoaxes like the moon landing and September 11th are still important to educate about. It necessarily will change your entire world view.
