The function of the United Nations Security Council (UNSC) is to maintain international peace and security. It addresses threats, fosters diplomatic resolutions, and authorizes military actions when necessary to protect global stability. The UNSC has 15 members, including five permanent members—China, France, Russia, the United Kingdom, and the United States—who hold veto power over resolutions. The council’s decisions can impose sanctions or authorize peacekeeping missions, making it a critical component of the UN's structure in addressing global conflicts.
