NATO in 2024

NATO (North Atlantic Treaty Organization) is an international military alliance consisting of 32 member states from Europe and North America. It was established at the signing of the North Atlantic Treaty on 4 April 1949. Article 5 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.[1] Article 6 of the treaty limits the scope of Article 5 to the islands north of the Tropic of Cancer, the North American and European mainlands, the entirety of Turkey, and French Algeria, the last of which has been moot since July 1962. Thus, an attack on Hawaii, Puerto Rico, French Guiana, the Falkland Islands, Ceuta or Melilla, among other places, would not trigger an Article 5 response.

Of the 32 member countries, 30 are in Europe and two are in North America. Between 1994 and 1997, wider forums for regional cooperation between NATO and its neighbors were set up, including the Partnership for Peace, the Mediterranean Dialogue initiative, and the Euro-Atlantic Partnership Council.

All members have militaries, except for Iceland, which does not have a typical army (but it does have a coast guard and a small unit of civilian specialists for NATO operations). Three of NATO's members are nuclear weapons states: France, the United Kingdom, and the United States. NATO has 12 original founding member states. Three more members joined between 1952 and 1955, and a fourth joined in 1982. Since the end of the Cold War, NATO has added 16 more members from 1999 to 2024.[2]

NATO currently recognizes Bosnia and Herzegovina, Georgia, and Ukraine as aspiring members as part of their Open Doors enlargement policy.[3]

Founding members and enlargement[edit]

Main article: Enlargement of NATO

NATO was established on 4 April 1949 via the signing of the North Atlantic Treaty (Washington Treaty). The 12 founding members of the Alliance were: Belgium, Canada, Denmark, France, Iceland, Italy, Luxembourg, the Netherlands, Norway, Portugal, the United Kingdom, and the United States.[4]

The various allies all sign the Ottawa Agreement,[5] which is a 1951 document that acts to embody civilian oversight of the Alliance.[5][6]

Current membership consists of 32 countries. In addition to the 12 founding countries, four new members joined during the Cold War: Greece and Turkey (1952), West Germany (1955) and Spain (1982). In 1990, the territory of the former East Germany was added with the reunification of Germany. NATO further expanded after the Cold War, adding the Czech Republic, Hungary, and Poland (1999); Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, and Slovenia (2004); Albania and Croatia (2009); Montenegro (2017); North Macedonia (2020); Finland (2023); and Sweden (2024).[4] Of the territories and members added between 1990 and 2024, all except for Finland and Sweden were either formerly part of the Warsaw Pact (including the formerly Soviet Baltic states) or territories of the former Yugoslavia. No countries have left NATO since its founding.

Currently, the North Atlantic Treaty Organization now covers a total area of 27,580,492 km2 (10,648,887 sq mi), since the accession of Sweden on 7 March 2024.

Membership aspirations[edit]

As of March 2024, three additional states have formally informed NATO of their membership aspirations: Bosnia and Herzegovina, Georgia, and Ukraine.[3]

Special arrangements[edit]

The three Nordic countries which joined NATO as founding members, Denmark, Iceland and Norway, chose to limit their participation in three areas: there would be no permanent peacetime bases, no nuclear warheads and no Allied military activity (unless invited) permitted on their territory. However, Denmark allowed the U.S. to maintain an existing base, Thule Air Base (now Pituffik Space Base), in Greenland.[14]

From the mid-1960s to the mid-1990s, France pursued a military strategy of independence from NATO under a policy dubbed "Gaullo-Mitterrandism".[15] Nicolas Sarkozy negotiated the return of France to the integrated military command and the Defence Planning Committee in 2009, the latter being disbanded the following year. France remains the only NATO member outside the Nuclear Planning Group and unlike the United States and the United Kingdom, will not commit its nuclear-armed submarines to the alliance.[16][17]

The defence spending of the United States is more than double the defence spending of all other NATO members combined.[19] Criticism of the fact that many member states were not contributing their fair share in accordance with the international agreement by then US president Donald Trump caused various reactions from American and European political figures, ranging from ridicule to panic.[20][21][22]

Political and popular support[edit]

Pew Research Center's 2016 survey among its member states showed that while most countries viewed NATO positively, most NATO members preferred keeping their military spending the same. The response to whether their country should militarily aid another NATO country if it were to get into a serious military conflict with Russia was also mixed. Roughly half or fewer in six of the eight countries surveyed say their country should use military force if Russia attacks a neighboring country that is a NATO ally. And at least half in three of the eight NATO countries say that their government should not use military force in such circumstances. The strongest opposition to responding with armed force is in Germany (58%), followed by France (53%) and Italy (51%). More than half of Americans (56%) and Canadians (53%) are willing to respond to Russian military aggression against a fellow NATO country. A plurality of the British (49%) and Poles (48%) would also live up to their Article 5 commitment. The Spanish are divided on the issue: 48% support it, 47% oppose.[26][27]
