What was the primary objective of the United Nations during the Korean War?

The primary objective of the United Nations during the Korean War was to help South Korea defend against North Korea. When North Korea invaded South Korea in June 1950, the UN quickly responded by calling for military assistance to repel the invasion. This marked one of the first significant actions taken by the United Nations in a conflict, reflecting its commitment to collective security and international peace. The UN Security Council passed resolutions that authorized member states to send military forces under the UN flag to aid South Korea. This intervention was aimed not only at stopping the aggression but also at upholding international law regarding sovereignty and territorial integrity. The successful defense of South Korea against North Korean forces was a crucial aim for the UN's involvement, leading to a prolonged military engagement that focused on maintaining peace and stability in the region.
