The members of the United Nations Security Council consist of 15 countries, five of which hold permanent seats—the United States, United Kingdom, France, Russia, and China. These five nations have the power to veto resolutions, granting them significant influence in international decision-making. Additionally, ten non-permanent members serve two-year terms, representing various regions to ensure broader global representation. The Council is tasked with maintaining international peace and security, addressing conflicts, and approving peacekeeping missions, making it a crucial component of the UN's function in global governance.
