President Kennedy was most effective during the Cuban Missile Crisis and was least effective during the Bay of Pigs Invasion.
The Cuban Missile crisis against what generals said Kennedy should do (which was basically nuke Cuba) Kennedy went about agreements with Russia to take the missiles out of Cuba. Which is important because it prevents a nuclear war.
The Bay of Pigs Invasion was just a complete disaster. Kennedy sent in rebel Cubans to try to overthrow Castro who was ruling Cuba at the time but decided not to have air support to help them. It is nicknamed a “perfect failure”.
