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.

He played Phoebe Buffay's husband Duncan in a 1995 episode of Friends. Zahn appeared in several films in the mid-1990s, including Tom Hanks' That Thing You Do!

Gore Vidal ( /ˌɡɔr vɨˈdɑːl/; born October 3, 1925) is an American author, playwright, essayist, screenwriter, and political activist. His third novel, The City and the Pillar (1948), outraged mainstream critics as one of the first major American novels to feature unambiguous homosexuality. He also ran for political office twice and has been a longtime political critic.

Vidal was born Eugene Luther Gore Vidal in West Point, New York, the only child of 1st Lieutenant Eugene Luther Vidal (1895–1969) and Nina Gore (1903–1978). He was born in the Cadet Hospital of the United States Military Academy, where his father was the first aeronautics instructor, and was christened by the headmaster of St. Albans preparatory school, his future alma mater. According to "West Point and the Third Loyalty", an article Vidal wrote for The New York Review of Books (October 18, 1973), he later decided to be called Gore in honor of his maternal grandfather, Thomas Gore, Democratic senator from Oklahoma.

Vidal's father, a West Point football quarterback and captain, and an all-American basketball player, was director of the Commerce Department's Bureau of Air Commerce (1933–1937) in the Roosevelt administration, was one of the first Army Air Corps pilots and, according to biographer Susan Butler, was the great love of Amelia Earhart's life. In the 1920s and 1930s, he was a co-founder of three American airlines: the Ludington Line, which merged with others and became Eastern Airlines, Transcontinental Air Transport (TAT, which became TWA), and Northeast Airlines, which he founded with Earhart, as well as the Boston and Maine Railroad. The elder Vidal was also an athlete in the 1920 and 1924 Summer Olympics (seventh in the decathlon; U.S. pentathlon team coach).
