The North Atlantic Treaty Organization (NATO) was the treaty signed by the Western European countries along with Canada and the United States in April of 1949.
NATO is an intergovernmental military alliance which constitutes a system of collective defense whereby its member states agree to mutual defense in response to an attack made by an external party.
