The United Nations Security Council (UNSC) is the organ of the United Nations charged with maintaining peace and security among nations. While other organs of the United Nations only make recommendations to member governments, the Security Council has the power to make decisions which member governments must carry out under the United Nations Charter. The decisions of the Council are known as United Nations Security Council Resolutions. The Security Council is made up of 15 member states, consisting of five permanent seats and ten temporary seats. The permanent five are China, France, Russia, the United Kingdom and the United States. These members hold veto power over substantive but not procedural resolutions allowing a permanent member to block adoption but not debate of a resolution unacceptable to it. The ten temporary seats are held for two-year terms with member states voted in by the UN General Assembly on a regional basis. The Presidency of the Security Council is rotated alphabetically each month. Members.
Security Council members must always be present at UN headquarters in New York so that the Security Council can meet at any time. This requirement of the United Nations Charter was adopted to address a weakness of the League of Nations since that organization was often unable to respond quickly to crises. The role of president of the Security Council involves setting the agenda, presiding at its meetings and overseeing any crisis. It rotates in alphabetical order of the members' names in English. There are two categories of membership in the UN Security Council: Permanent Members and Elected Members. Permanent members
