Planned fake UFO attack?

I was watching a documentary on Amazon Prime called Unacknowledged and they were claiming that UFO’s and Aliens exist and the American government not only has possession of crafts, but can also fly them.

There are documents of planned fake attack’s on their own American people to sway their political opinions and give them a reason to go to war with nation’s, which they can then use as an excuse for their military budget. As long as they’re at war, no one will question their budget. But what I found interesting was they said they had witnesses that said they’re planning a fake UFO attack. So it would be human pilots in UFO’s to make it look like we’re being attacked by alien’s when in reality they aren’t attacking us at all. Now I don’t understand why exactly they would do this. To get more funding? To rally up the world together? I don’t really understand the benefit in staging an attack.
