My personal opinion is that these are aerial craft from black budget special access programs. The fact that the Pentagon is releasing these means that they will soon admit to having this technology, and the secret arms race will become public.

It is also my belief that the technology is ‘ours’ (I used that word loosely), and you only need to go back to how the CIA commissioned the various stealth and high altitude supersonic designs in the 60s that didn’t become common knowledge for decades to see how that potential for hyper secret technology can exist and remain compartmentalized from even the highest levels of ‘government’.
But to your point, there is absolutely no strategic reason to tip your hand to having such cards unless you need it as a deterrent for war... which to me, if true, is a worrisome thought, because I wouldn’t show those cards unless absolutely necessary.

Yep, to keep China on a leash.
