NATO membership is the question of which states belong to the North Atlantic Treaty Organization, a military alliance of thirty-two European and North American countries built on a system of collective defense. Joining is governed by Article 10 of the North Atlantic Treaty, which permits the alliance to invite other European states able to further its principles and contribute to North Atlantic security. A government's position on NATO membership covers both its own participation and its stance on the alliance's enlargement to other states.
