The major aim of the United Nations Organization (UNO) is to "maintain international peace and security." The United Nations was established in 1945 after the end of World War II to promote international cooperation and prevent future conflicts. The organization works towards this aim by facilitating diplomatic negotiations and providing a forum for member states to discuss and address issues affecting international peace and security. The UN also has several bodies, such as the Security Council, which can take action to prevent conflicts and promote peace. The UN's efforts in maintaining international peace and security have included peacekeeping missions, humanitarian aid, and conflict resolution efforts in various parts of the world.
