Thank you for the clarity you provide to this literary device, Greg.
I often think of the model of George Michael Evica stated by Charles as the very essence of the military-organized crime-intelligence mode of operation/organizational chart, the Secret Team of Prouty.
Reference to this as a given--and the event was neither ad hoc nor vest pocket--the various false sponsors are adjusted to their position in the tapestry/mandala as so many terra cotta warriors, painstakingly created and buried, keeping archaeologists busy speculating.
Donald Gibson in Creation of the Warren Commission gives the account of Rostow's call and states Rostow conferred with a few people, perhaps Acheson.
What I find of value in this observation is the resistant Johnson and Hoover, the frequently hyped false sponsors, become obedient order takers albeit under the guise of "be reasonable, do it my way".
Acheson's daughter married William Bundy and McGeorge was a Dulles man and whose man was Dulles, for he is not a be-all and end-all.
Notwithstanding David Talbot's styling the once and former DCI "The Chairman of the Board of the JFK Assassination" (coming soon: The Devil's Chessboard: Allen Dulles, the CIA, and the Rise of America's Secret Government).
Did Allen Dulles actually say, "I'll get you, JFK, and your little dog, too"?
Or was it rather, ". . .that little Kennedy. . .he thought he was a god. . . ."
The scenario of Prouty is akin to the prior conferences posited in Seven Days in May and Executive Action.
Our friend a former Army intelligence analyst establishing the Chinese order of battle after the Korean War would decades later tell me what a dangerous man Kennedy was--the most stunning thing said in the ten years we knew him, a cold blast when the walk-in door is opened.
Our friend from the Boston and New York financial houses writing Caro about Eliot Janeway's "hissing" what "a dangerous man this Kennedy is".
The widespread yet unseen atmosphere of treason presented in Douglass' Unspeakable.
In the general sense, we are on firm ground stipulating a widespread and visceral distaste for Kennedy's peace pursuit and promotion of Third World self-determination versus the looking glass Cold War so dear to the milint operation and its corporate and financial clients.
That Prouty depicted an actual event is not the case.
That said, Allen Dulles wrote a book beginning November 1961.
In November 1963 he was in Dallas signing copies and would be on Rostow's Commission pushing the lone assassin theory.
And thus we see the origin of the classic phrase Dulles ex machina
