There's a vast gulf between "believing that spaceships from other planets have crashed and some elite division..." and subscribing to your theory which is so far only supported by you insisting to us what "you want" as a theoretical deep state government apparatus. From my perspective, it would seem like the widespread belief that terrorists could crash planes into buildings resulted in a lot of public money, enlistment, and support flowing into the US Military over the early 2000s.

You're presenting a false choice between two conspiracy theories as the only ways to view this situation, which certainly doesn't make your particular conspiracy theory look any more credible.
