Who was ultimately responsible for the Cuban Missile Crisis? Why do you think so?

Though Kennedy is most to blame in terms of the increasing in hostility in the region, Khrushchev was the individual that created the crisis as it existed. Kennedy's actions were a direct cause of Soviet interference, yet Khrushchev's decision to place nuclear weapons on the island is the cause of the crisis. Hope this helps or solves your question
