Seriously, I'm a history teacher. Seriously, I have an M.A. in history.
I know you're including "overthrows" there, but the original point was assassinating heads of state. By the CIA.
I'd say that Mossadegh and Allende are the only "almost-certains" of the assassinations on your list.
The CIA was not involved in the assassination of Diem. Not even in his overthrow as far as I know. Our embassy was.
The CIA was not involved in the death of Saddam. I don't know what prompted you to mention him. Same with Ghadaffi and Solimari. If it's done by a foreign court or a military strike, that's not the CIA. And Solimari was not a head of state.
Seriously, do I try to tell you about the nuts and bolts of your job?
