Are the US intelligence "demanding to be blindly trusted" ?

Or - hypothetically - if the US intelligence is only 80% reliable - isn't it still worth signalling to their Russian counterparts that "we see you, don't try it" ? That might be the real intended audience.

Isn't this also a fairly plausible accusation about Russia, given previous operations, e.g. "little green men" https://en.wikipedia.org/wiki/Little_green_men_(Russo-Ukrain... and apartment bombings https://en.wikipedia.org/wiki/Russian_apartment_bombings
