This theory actually makes more sense than any other proposed to date.
I have to admit...I agree. The Soviets were more than capable of doing something like this. Reason? It would pump up Americans to think that not only were the Soviets a threat, but the aliens were a threat. The US would have spent an entire decade studying the little men and the advanced technology....and probably in the end come to realize that they’d be ‘pranked’. You can’t admit this in public, and it’d really mess up the careers of a number of Air Force Generals who took this serious.
