The cuban missile crisis was also his fault. President Kennedy wanted to blockade a border between the US and cuba. He warned the americans that they were going to use military force if they needed to if there's a threat to the national security. He’s made the mistake of putting fear into the americans thinking they would have a nuclear war. President Kennedy came into an agreement with khrushchev that they would not invade cuba and that they should remove the missile. If Kennedy never intended to invade cuba an mov a mistake like he did in the Bay of Pigs no missile threat would have been out. President Kennedy is responsible for his actions in the Bay of PIgs and the cuban missile crisis threat. President kennedy was careless.
Last reasons why JFK was not a good president was because of the vietnam war. Kennedy sent 400 special forces to south vietnam. He wanted to disrupt the south vietnamese base and supply lines. President Kennedy was so selfish that he wanted to defeat the south vietnamese army. 58,000 people were killed in the vietnam war. Kennedy sent 9,000 troops to south vietnam. Vietnam war escalates. JFK is assassinated in Dallas, Texas in November
