The major concern of the United Nations Organization (UNO) is world "peace." The UNO was created after World War II to prevent future wars and promote peaceful coexistence among nations. The UNO works towards this goal by facilitating international cooperation, promoting human rights, and providing a forum for countries to discuss and resolve disputes peacefully. It also deploys peacekeeping forces to regions where conflicts have broken out, and provides humanitarian aid to those affected by war and other crises. While the UNO also works on other important issues such as trade, health, and cooperation, its primary focus is on maintaining international peace and security.
