Before we get into the List of NATO Counties, let’s have a quick intro about NATO and how it works.
North Atlantic Treaty Organization in short NATO is an international alliance that consists of 30 member states from Europe, North America, and Asia. It was established at the signing of the North Atlantic Treaty on 4 April 1949.
Article Five of the treaty states that if an armed attack occurs against one of the member states, it shall be considered an attack against all members, and other members shall assist the attacked member, with armed forces if necessary.
