The significance of the naval quarantine of Cuba was that it effectively prevented the Soviet Union from delivering more missiles to Cuba and potentially starting a nuclear war. It also showed the resolve of the United States in standing up to the Soviet Union and protecting its interests in the Western Hemisphere. By implementing the quarantine and making it clear that any Soviet ships attempting to breach it would be met with force, the United States was able to peacefully resolve the Cuban Missile Crisis and prevent further escalation of tensions between the two superpowers.
