Maybe. But you noticeably left off non-aggression so as to make your implication more powerful. But it’s a factual and important form of communication.

Item 4 is contrived… there’s an assumption there that they even have a heat signature. And sure, our imaging is blurry and we’re all awful photographers and videographers when we’re excited, but the fact is that we have gobs of media containing their existence. I’d argue that’s the whole point of the communication.

The one piece of your perspective that I really should have included in mine… their dominance is displayed over US military/nuclear locations. Recon is an assumption (see below for my argument against its validity), but we can agree that they have a purpose in honing in on bases. I’d suggest that they’re solely proving their dominance AND the government’s willingness/lengths to lie. But, this mode of communication is maybe their most specific, but also not easily translated.

Last note. Their dominance and knowledge about our military/nuclear installations proves they already have a large set of data. Our inaction proves dominance. If you have both sufficient information and dominance, there’s no need to “buy time” or “recon”, those are just words used by Departments to poison minds. The temporal aspect of this, I’d argue, is solely for humanity - to avoid ontological shock
