Member States

The NATO Alliance consists of 28 member states from North America and Europe. Article Five of the treaty states that if an armed attack occurs against one of the member states, it should be considered an attack against all members, and other members shall assist the attacked member, with armed forces if necessary.

Over the past two decades, the Alliance has developed a network of structured partnerships with countries from the Euro-Atlantic area, the Mediterranean and the Gulf region, as well as individual relationships with other partners across the globe. Today, NATO pursues dialogue and practical cooperation with 41 partner countries and engages actively with other international actors and organisations on a wide range of political and security-related issues.
