Step-by-step explanation:
President Kennedy's main strategy in dealing with the Cuban Missile Crisis was to impose a naval blockade around Cuba until the crisis was resolved. On October 22, 1962, Kennedy announced a naval blockade (referred to as a "quarantine") to prevent Soviet ships from approaching Cuba and delivering additional missiles. This strategy put pressure on the Soviet Union and ultimately led to a resolution, with the Soviets agreeing to remove their missiles from Cuba and the United States agreeing later to remove its missiles from Turkey.
