from Wikipedia article about David "I saw the aliens" Grusch

Australian political commentator Caitlin Johnstone pointed out that this resurgence of UFO/UAP coverage is coincident with a renewed U.S. emphasis on weaponizing space: "Is it a coincidence that this new UFO narrative began its rollout in 2017, around the same time as the rollout of the Space Force? Are we being manipulated at mass scale about aliens and UFOs to help grease the wheels for the movement of war machinery into space?"

Johnstone's speculation is not far fetched. There is a history of military intel using UFO claims and hysteria to smokescreen foreign intel regarding our stealth planes, and other experiments and efforts. That could apply to the weaponization of space. These theoretical weapons would be pointed downward, at human targets--not outwards, at approaching flying saucers.
@JohnShirley2023 all that makes sense, plus it makes a convenient distraction from literally anything else you might want to distract from - for instance, a bunch of upcoming congressional votes that could destroy internet privacy forever - since "whoa aliens" will always draw the clicks and eyeballs. There's no conflict between that and what you're talking about either, it's a useful noise generator on two different timelines/subjects
