This is the part I never understand about this approach though - The Bay of Pigs invasion happened on Kennedy’s watch, as did his push back on the Missile Crisis and the embargo so this narrative that he was soft on Cuba or something just isn’t the case.
More conspiratorial theorists like to speculate that the CIA hoped to lure the US into a full-scale invasion of Cuba by escalating the Bay of Pigs invasion. By refusing to provide direct air support, Kennedy essentially stopped that from happening and doomed the invasion and ruined Allen Dulles’ reputation. I have no clue how valid these theories are, but it’s what’s usually cited.
But the failed invasion of Cuba was not an isolated incident. JFK was undermined by an intelligence community he did not control many times, another famous one being the CIA-backed military coup against Charles de Gaul which also failed. But the French foreign minister to the US has record of a conversation with Kennedy where he says he is not fully in control of his country’s foreign policy.
