A National Security Council (NSC) is usually an executive branch governmental body responsible for coordinating policy on national security issues and advising chief executives on matters related to national security. An NSC is often headed by a national security advisor and staffed with senior-level officials from military, diplomatic, intelligence, law enforcement and other governmental bodies. The functions and responsibilities of an NSC at the strategic state level are different from those of the United Nations Security Council, which is more of a diplomatic forum.
Occasionally a nation will be ruled by a similarly named body, such as "the National Security Committee" or "Council for National Security". These bodies are often a result of the establishment or preservation of a military dictatorship (or some other national crisis), do not always have statutory approval, and are usually intended to have transitory or provisional powers. See also: coup d'état.
The United Nations Security Council (UNSC) is one of the principal organs of the United Nations and is charged with the maintenance of international peace and security. Its powers, outlined in the United Nations Charter, include the establishment of peacekeeping operations, the establishment of international sanctions, and the authorization of military action. Its powers are exercised through United Nations Security Council resolutions.
The Security Council held its first session on 17 January 1946 at Church House, Westminster, London. Since its first meeting, the Council, which exists in continuous session, has travelled widely, holding meetings in many cities, such as Paris and Addis Ababa, as well as at its current permanent home at the United Nations Headquarters in New York City.
There are 15 members of the Security Council, consisting of five veto-wielding permanent members—China, France, Russia, the United Kingdom, and the United States—based on the great powers that were the victors of World War II, and 10 elected non-permanent members with two-year terms. This basic structure is set out in Chapter V of the UN Charter. 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 a crisis.
National security is the requirement to maintain the survival of the state through the use of economic, diplomacy, power projection and political power. The concept developed mostly in the United States of America after World War II. Initially focusing on military might, it now encompasses a broad range of facets, all of which impinge on the non military or economic security of the nation and the values espoused by the national society. Accordingly, in order to possess national security, a nation needs to possess economic security, energy security, environmental security, etc. Security threats involve not only conventional foes such as other nation-states but also non-state actors such as violent non-state actors, narcotic cartels, multinational corporations and non-governmental organisations; some authorities include natural disasters and events causing severe environmental damage in this category.
Measures taken to ensure national security include:
There is no single universally accepted definition of "National Security" since there are some differences on describing National as State and everything consist in a nation. The variety of definitions provide an overview of the many usages of this concept. The concept still remains ambiguous, having originated from simpler definitions which initially emphasised the freedom from military threat and political coercion to later increase in sophistication and include other forms of non-military security as suited the circumstances of the time.
