I'm as a paranoid about the CIA as the next guy but the idea that they would try something like this without political cover seems unlikely to me. Further the idea the Joe Biden would even come close to signing off on this doesn't seem like any version of him. Maybe if he's genuinely off the rails and K. Harris or the Sec. Def. really is running things - maybe then I'd believe this but failing that I can't imagine him being that kind of person or anyone in the chain signing off on this without him on board.

If it was the US - and I think the chance of it not coming to light if it was to be vanishingly small - I would be really interested in the details. I would expect someone handing it to Biden as a fair acompli and him just going with it.
