So is Biden going to be burned at the stake by the Inquisition?
By the way, does anybody remember that a few months ago the NSA or some other government organization came out and said that all those weird UFO videos were real and that they didn't know from where the fuck they came from? I remember that one video where 2 pilots are following that weird thing and as soon as they came close to it the thing flew out of their sight and radars in like a second, pretty spooky.
The fact that no forces have opened fire on them in recent history tells me its probably US or US-Ally stuff.
When it comes to threat assessment, Aliens is pretty much a non-starter. Not just for the whole "Aliens don't exist" bit, but more that, if there is a technological force that can achieve the level of technology to come to earth in force and fuck shit up, the goose is already cooked. Whereas intercepting one gives the potential of capturing some tech. Its a one in a billion longshot, but better that than nothing. Remember, if they have the capacity to invade the planet brought with them, over such long distances, they probably came to do exactly that. So triggering some sort of retaliation just shows they brought military force with intent.
If its a near-peer threat with more advanced technology than we expected, shoot it down and secure the technology. Whoever it is, they'd have a hard time really doing anything about the situation, as long as the encounter was in either the exclusion zone of the navy, or in/over US territorial airspace. And since most evidence would indicate that for humans, these have to be some sort of drone craft, there's not blood on hands. Anyone stepping up and saying "Hey the US shot down our Super Advanced stuff" is going to have a lot of explaining to do on the global stage.
And if its a US asset, then orders from sufficiently high up will be "Don't touch it". They don't need to know why, and simple orders to ghost mysterious contacts and observe would be fine. Why they are just flying out in the middle of random places with US presence? No idea, could be some effort to test 'real world' effectiveness, especially if the real trick is some sort of detection confusion and countermeasure systems.
I do secretly hope that Dementia Joe slips up on stage and just says "We can't fight China, we're too busy with the Aliens!" one day.
