> American military made a grave mistake by giving access to the morons of the Brazilian military, who are letting knowledge of this spread like a fire (and misusing it for petty profit and inside jobs to justify a police state). Israel, UK and France also have access, but are much more professional.

They use it all the time, just with much more finese than any other advesary ever imagined.
Just recently, they used it to catch three of my subs.
Darknet never dies.
