The stupid take is the one you propose, it's ridiculous. So USAF has secret decoys in WWII and before, that followed WWII fighters, and hovered over people's houses, among millions of other sightings worldwide? So advanced yet they don't send them to war?

The energy required for some UFO manoeuvres is far above what we know how to create: https://youtu.be/HlYwktOj75A?si=Q68f2ODxgO_IpGlv&t=770

Then Senators should stop blaming Iran for them. It’s irresponsible

They get money from the 'war with Iran' lobby. From their perspective such statements are rational.

That was a US Representative, not a Senator, but point taken

> People should've already learned this, if they were not so stupid.

You're falling in the same trap as conspiracy theorists, though: Putting out almost non-falsifiable statements, and then claiming you know better and are smarter. Either it will be revealed that it was USAF and you can feel smug about being correct, or it will not come out and you can still feel smug about being correct because no one can prove you wrong.

Third option: You can draw conclusions from past projects made public where this exact thing happened dozens of times.
