According to Von Braun, the West would begin to war with Russia creating intense instability and fear. Then comes the Alien Threat PsyOp, where unidentified flying objects suddenly become an issue, and a potential threat. Of course, this is after years of the same people relegating the topic to the lowest level of concern, and the government and media refusing to admit they even exist.

And, once space is weaponized, once that kind of satellite technology is accepted by the public there is very little freedom for humanity as the level of surveillance and control one can enforce from space is devastating.
