From the government as a whole? No. But for some specific department to get funding over others? Yeah, probably that sort of jockeying for funds happens all the time.
Even then, I don't think they would need to create a fleet of drones to buzz around military bases to scare up a pretext for more funding. That's comic book logic.
That's not at all what's happening. I don't think the MIC invests heavily in producing false-flag events.
But they do evidently invest heavily in PR and "think tank" activities to drum up support, including misconstruing harmless events as national security threats.
