The North Atlantic Treaty Organization (NATO /ˈneɪtoʊ/; French: Organisation du Traité de l'Atlantique Nord; OTAN), also called the North Atlantic Alliance, is an intergovernmental military alliance between several North American and European states based on the North Atlantic Treaty which was signed on 4 April 1949. The organization constitutes a system of collective defence whereby its member states agree to mutual defence in response to an attack by any external party. Three NATO members (the United States, France and the United Kingdom) are permanent members of the United Nations Security Council with the power to veto and are officially nuclear-weapon states. NATO's headquarters are located in Haren, Brussels, Belgium, while the headquarters of Allied Command Operations is near Mons.
