No, Dulles and the generals left those Cubans stranded at Bay of Pigs, not Kennedy. Before the operation, he told them unequivocally that US forces were not going to be involved and that was a condition of him allowing it to proceed.
They thought they could back him into a corner and force him to do what they wanted. Dulles and our treasonous generals didn’t count on him having a backbone and standing up to them.
And they murdered him for it
But US forces were involved. For three hours plus before the invasion U.S. 1 was closed to southbound traffic - a massive armored equipment flow through Miami. I lived there on SW 22nd Avenue and the highway, was awakened, had Cuban friends who were part of the landing, witnessed armored equipment from as far away as Fort Benning.. None of the promised air cover was sent from Homestead AFB and Pensacola Naval Air. Zip, nada. We screwed those brave Cubans, set them up and that, IMHO, was as bad a blemish on American history as the recent Afghanistan fiasco.
