The Cuban Blockade refers to the U.S. government's action to restrict trade and military supplies to Cuba during the Cuban Missile Crisis in October 1962. This was a response to the discovery of Soviet nuclear missiles on the island, which posed a direct threat to U.S. national security. The blockade aimed to prevent further shipments of military equipment and to pressure the Soviet Union to remove the missiles. The blockade lasted for 13 days and was a critical moment in the Cold War, highlighting the tensions between the United States and the Soviet Union. Ultimately, the crisis was resolved when the U.S. agreed to remove its missiles from Turkey in exchange for the withdrawal of Soviet missiles from Cuba.
