Kissinger outed by former KGB/Polish intelligence/CIA Michael Goleniewski for being a soviet.

I believe Goleniewski was mkultraed - handler CIA Herman Kimsey (CIA op in media). I believe he was part of a failed plot after the clumsy JFK assassination. Too much heat on the CIA to follow through. Goleniewski gets pissed and starts outing people after they fail to keep their promises. Ends up on the CIA watch list and then eventually goes missing.
