Hi there Enlil,
First of all, there was no "cold war". If you understand major Jordan's testimony, understand that the banksters funded the Bolsheviks, read "None Dare Call it Conspiracy" (available free online), then it will be much clearer.
Secondly, here's the take on the "aliens" that many other researchers and I agree with:
Bill Cooper, ex-Navy Intelligence, researched this UFO subject for decades, had plenty of insider access, and came to the same conclusion.
My belief is that they're making the UFOs and whatever other infrastructure needed for a grand deception. Their tactics of "shock and awe" are a proven method. I think they're going to shock the hell out of people with either a pandemic or a nuclear war and then the "fiendly aliens" are going to "save us" (by microchipping everybody LOL).
There is plenty of disinfo around:
America & China Defend Pacific against Alien Invasion : Top Secret Military Pact
Gordon Duff was forced to put this out. It is disinfo but I'm not sure exactly why and how it's supposed to work.
The "elites" are demonic. WWI and WWII were, IMO, grand mass human sacrifices in large part. They will never be on "our side". If you don't believe in Lucifer, it doesn't matter. What matters is that plenty of other people do and it will affect you.
A quick summary of the situation as I see it.
