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 countries based on the North Atlantic Treaty that was signed on 4 April 1949.[4][5]
NATO constitutes a system of collective defence whereby its member states agree to mutual defense 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 Headquarters are located in Haren, Brussels, Belgium, while the headquarters of Allied Command Operations is near Mons, Belgium.
Several NATO officials come to visit Alnus and manage to purchase a map of Special Region in Episode 21 and Chapter 72.
