Dulles and Dallas
[b/Dulles could hardly have expected to get Truman to recant publicly. So why was it so important for Dulles to place in CIA files a fabricated retraction? I believe the answer lies in the fact that in early 1964 Dulles was feeling a lot of heat from many who were suggesting the CIA might have been involved somehow in the Kennedy assassination. Columnists were asking how the truth could ever be reached, with Allen Dulles as de facto head of the Warren Commission.
Dulles had good reason to fear that Trumans limited-edition Washington Post op-ed of Dec. 22, 1963, might garner unwanted attention and raise troublesome questions about covert action, including assassination. He would have wanted to be in position to dig out of Larry Houstons files the Truman retraction, in the hope that this would nip any serious questioning in the bud.
As the de facto head of the Warren Commission, Dulles was perfectly positioned to protect himself and his associates, were any commissioners or investigators or journalists tempted to question whether Dulles and the CIA played a role in killing Kennedy.
And so, the question: Did Allen Dulles and other cloak-and-dagger CIA operatives have a hand in John Kennedys assassination and in then covering it up? In my view, the best dissection of the evidence pertaining to the murder appeared in James Douglasss 2008 book,
JFK and the Unspeakable:

After updating and arraying the abundant evidence, and conducting still more interviews,
Douglass concludes that the answer is Yes.
