The United Nations Security Council (UNSC) is one of the six principal organs of the United Nations, tasked with maintaining international peace and security. Established in 1945, the UNSC has 15 members, including five permanent members with veto power: China, France, Russia, the United Kingdom, and the United States. It has the authority to impose sanctions, authorize the use of force, and deploy peacekeeping missions. The Council addresses global conflicts, threats to peace, and works to prevent war through diplomacy and collective action. Its decisions are legally binding on UN member states, making it one of the most powerful UN bodies.
