The Bay of Pigs failed largely due to President Kennedy breaking his promise to provide air cover.
Actually, according to what I recently read but can’t cite the source (seems like I read a recent book about Eisenhower that I can’t recall the title of), Eisenhower was asked by his inner circle (which was staffed by heavyweights) if it wasn’t dangerous to create the CIA group which invaded at the Bay of Pigs. On the basis that it might be used to launch a poorly prepared, ungrounded attack on Cuba. Ike replied, “Not while I am president,” and his adviser said that that caveat was what he was worried about.Eisenhower briefed JFK about the program and warned that it should only be used when there was a plausible alternative to Castro. JFK was a lot less attentive to Eisenhower before taking office than he had every reason to wish afterward that he had. The invasion had no leader with the stature to claim legitimacy as the president of Cuba.
When JFK explained to Ike that he had withheld air support to keep US fingerprints off the operation, Eisenhower was dismissive of the conceit that, in any such operation, US involvement could plausibly be denied.
And Naval cover. The Cuban Freedom Fighters were promised that our ships would soften up their landing zones and keep the Castro forces suppressed.
Kennedy didn't have the decency to call the whole thing off, and then he didn't have the decency to inform the Cubans that he was withholding the air and naval support that they thought they were going to get.
It was this bungled invasion that caused the Cuban Missile crises. Had it never happened, the Soviets wouldn't have put missiles in Cuba to defend against another such attempted invasion.
Actually he promised NOT to provide air cover. The CIA thought they could force him to buy creating a mess on the ground. Then it would be a full on US invasion.
He didn’t let them bully him.
JFK was a serial adulterer with links to the mob. He had no major accomplishments while President except to let the Soviets have missiles in Cuba while publicly shipping empty crates back to Russia,
