Actually the best argument would be that the Soviets didn’t raise holy hell about it being fake.

Apollo 11 was able to be tracked by radio the entire trip to the moon. The radio transmissions and The television broadcast was unencrypted over plain radio. I’m sure the Soviets were able to verify the entire mission in real time. If there was even a hint that the moon landing was fake, the Soviets would have been throwing it in the US’s face the instant it happened.
