Lynch L. Grayston, Decision for Disaster: Betrayal at the Bay of Pigs
What I get out of these and other sources I've read is that the operation was undermined not so much by JFK himself as by some of the advisors he relied on, especially Dean Rusk, who represented the policies of the Dulles brothers' old opponent Dean Acheson. Acheson, Paul Nitze, Maxwell Taylor, and others aligned with them had been opposing J.F. Dulles' foreign policy during the Eisenhower administration and gained influence with JFK's election. They scapegoated Dulles for their own undermining of the Bay of Pigs in order to promote their own foreign policy agenda, IMO.
Thanks for posting the links I'll look into them too first chance I get to unglue myself off this board.
