An existing theory by some is that the deep state and military industrial complex has such a need to be involved in wars that eventually they won't be able to scare us into believing there is a need. We are seeing this with the waning public support for the Ukraine conflict. So, the thought is that eventually they will start floating the UFO invasion scenario. Under this scenario, there will be an attack and many people will die, but it won't be at the hands of aliens.
That’s a very interesting theory.
The need for more money not just for defense spending, but much much more for the special research, projects, darpa and domestic security. Obviously not for the reason they suggest, but you always need a decoy or boogeyman. Other than China, we are running out of emerging foreign threats to use. So why not UFO invasion?
More than likely, if it doesn’t just get laundered into people’s pockets, it will go into social programs and large scale social engineering / domestic redistribution.
Suggesting that a lot of people would need to die though definitely puts the conspiracy theory on a whole different level.
