I'm going to take a guess that the OP has not worked with the CIA nor has he ever known anyone in the CIA nor does he understand what the CIA does.
No I didn't work for them
No I don't think I know anyone who does
but I got a very good idea what they do
To convince me, you need to provide something beyond an interesting story you thought up. What evidence exists to support this counter-intuitive black-op? I don't even see a motive. What is the CIA's interest in owning an exchange in Japan?
