A Security Council in international relations refers to a body, typically within an organization like the United Nations (UN), responsible for maintaining international peace and security. The UN Security Council comprises 15 member states, including five permanent members with veto power. Its main functions include responding to conflicts, authorizing military interventions, and sanctioning states threatening peace. The Security Council's resolutions and decisions can significantly impact diplomatic relations and global security strategies. By promoting cooperation, the council aims to prevent conflicts and ensure stability in the international community.
