President Kennedy's decision not to provide naval and air support to
the rebels is seen by most analysts as the reason why the invasion
failed.

And the reason behind that was a constricted view of the problem.
Kennedy and his inner circle excluded information that should have
told them that the Cubans were not going to rise up against Castro
when the invaders landed, that his army was loyal and competent, and
that his air force was likewise. They expected the Cubans to rise up
against Castro and the army to turn on their ruler. They thought the
Cuban Air Force was incompetent. They were wrong on all counts
leading to perhaps the greatest fiasco in U.S. foreign relations
history. Groupthink played a big part in that terrible decision (cf.
Irving Janis, "Victims of Groupthink," Chapter 2). Fortunately the
Kennedy administration learned from that and did much better during
the Cuban missile crisis. Sadly, I don't see any similar learning
happening in the current administration.
