What is the primary function of the United Nations?

The primary function of the United Nations is to promote peace and cooperation among countries. Established in 1945 after World War II, the UN was created to foster international dialogue and prevent future conflicts. It works through various specialized agencies and committees to facilitate cooperation on issues such as security, human rights, development, and humanitarian efforts. The UN also plays a vital role in conflict resolution and peacekeeping missions around the world, aiming to maintain international peace and stability.

The other options do not accurately reflect the core mission of the UN. Promoting sports and entertainment falls outside the UN's scope, as does providing military support, which only occurs in specific contexts such as peacekeeping operations and with the consent of member states. While the UN does address international trade through its agencies, regulation of trade is not its primary focus. The emphasis on peace and cooperation distinguishes the UN as a significant global institution dedicated to diplomatic relations and collaborative governance among nations.
