Kennedy himself cancelled the air support, and sea support, for the Bay of Pigs invasion. He didn’t want the appearance of the invasion being an American operation, and he altered the plan which Ike had designed before Kennedy took office. Obviously that fooled no one, it simply left the invasion force sitting ducks.

Thanks for the reference; I read Dereliction of Duty a while back and will check it out again on this. Kennedy did alter Ike's design (and Ike later asked him if he really thought anyone wouldn't realize the U.S. was involved), but he did so at Rusk's recommendation, after Rusk initially tried to reduce the number of planes to be used in the operation, and after Rusk had falsely told McGeorge Bundy that Stevenson had threatened to resign over the air strikes--see pp. 77 and 154 of Grayston L. Lynch, Decision for Disaster.
