I think the CIA's involvement is highly doubtful. I base this not on evidence but on how amateurish the whole thing looked. Not that the CIA hasn't bungled things in the past, but they've certainly read the book on how to pull off a coup.
CIA bungled the bay of pigs. Seriously, how do you "fake a coup"? - Sure. We fail? - Yep. You get to hang after "enhanced interogation" and your family name will be blackened for a few years. - No problem. Anything for our great leader. p.s.: speaking of inept coups: https://en.wikipedia.org/wiki/1991_Soviet_coup_d'%C3%A9tat_attempt Interesting to note that this coup that [in consequence of failure] installed the very West friendly Yeltsin did not result in anyone important facing serious consequences. - would you like to volunteer to lead a fake coup, Colonel?
But the Bay of Pigs wasn't a coup; it was an invasion and attempted overthrow from the outside, if I'm not mistaken. CIA handled successful coups in other Latin American countries (Guatemala and Chile are the two come come to mind; don't know if there are others). I can't imagine that the CIA would attempt a coup in a NATO country. But even if they did they would surely have the presence of mind to arrest the president and take over the media, no? Those are the two most important things that didn't happen in Turkey. Not sure what the USSR connection is. That most certainly wasn't a CIA operation. That resulted from the military viewing Gorbachev as too friendly to the west. Glasnost wasn't high on the Soviet military's to-do list, and for good reason (from their perspective). My guess is that no one was really held to account, because a) Russia was so chaotic immediately after the collapse, and b) this left the military leaders as power brokers. I think this position is supported by the result that many of the former Soviet military leadership became very rich in the 1990s when the new oligarch class rose.
Of course BoP wasn't a coup but the salient point was that best laid plans of mice and men can go wrong. Per hollywood ("the good shepherd") it was due to intel leakage. I also recently posted regarding the coup against De Gaul and apparently that is not contested. Indeed, cutting the head of the snake is an excellent way to get things done but not if the said snake finds unexpected input from other interested parties. In any event, the Turks are sure acting as if that is the case, so not sure what you make of that. Granted it could all be grand theatre. Have no comments regarding Yeltsin's rise to power and the emergence of the Jewish Oligarchs but it is always good to remember Putin was Yeltsin's hand picked successor. And you may have forgotten about this too or possibly you are too young. How does one go about acclimating a nation viewing itself as "exceptional" to the dismantling of their own empire ... Just remember we are mostly fed lies.
