The North Atlantic Treaty Organization, also called the North Atlantic Alliance, is an intergovernmental military alliance of 32 member states—30 European and 2 North American. Established in the aftermath of World War II, the organization implements the North Atlantic Treaty, signed in Washington, D.C., on 4 April 1949. NATO is a collective security system: its independent member states agree to defend each other against attacks by third parties. During the Cold War, NATO operated as a check on the threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and the Warsaw Pact, and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa. The organization's motto is animus in consulendo liber. The organization's strategic concepts include deterrence.
The North Atlantic Treaty, also known as the Washington Treaty, forms the legal basis of, and is implemented by, the North Atlantic Treaty Organization (NATO). The treaty was signed in Washington, D.C., on 4 April 1949.
The Partnership for Peace is a North Atlantic Treaty Organization (NATO) program aimed at creating trust and cooperation between the member states of NATO and other states mostly in Europe, including post-Soviet states; 18 states are members. The program contains 6 areas of cooperation, which aims to build relationships with partners through military-to-military cooperation on training, exercises, disaster planning and response, science and environmental issues, professionalization, policy planning, and relations with civilian government. During policy negotiations in the 1990s, a primary controversy regarding PfP was its ability to be interpreted as a program that is a stepping stone for joining NATO with full Article 5 guarantees.
The Intermediate-Range Nuclear Forces Treaty was an arms control treaty between the United States and the Soviet Union. US President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev signed the treaty on 8 December 1987. The US Senate approved the treaty on 27 May 1988, and Reagan and Gorbachev ratified it on 1 June 1988.
Atlanticism, also known as Transatlanticism, is the ideology which advocates a close alliance between nations in Northern America and in Europe on political, economic, and defense issues. The purpose is to maintain or increase the security and prosperity of the participating countries and protect liberal democracy and the progressive values of an open society that unite them under multiculturalism. The term derives from the North Atlantic Ocean, which is bordered by North America and Europe.
The Treaty on the Final Settlement with Respect to Germany , more commonly referred to as the Two Plus Four Agreement , is an international agreement that allowed the reunification of Germany in October 1990. It was negotiated in 1990 between the 'two', the Federal Republic of Germany and the German Democratic Republic, in addition to the Four Powers which had occupied Germany at the end of World War II in Europe: France, the Soviet Union, the United Kingdom, and the United States. The treaty supplanted the 1945 Potsdam Agreement: in it, the Four Powers renounced all rights they had held with regard to Germany, allowing for its reunification as a fully sovereign state the following year. Additionally, the two German states agreed to reconfirm the existing border with Poland, accepting that German territory post-reunification would consist only of what was presently administered by West and East Germany—renouncing explicitly any possible claims to the former eastern territories of Germany including East Prussia, most of Silesia, as well as the eastern parts of Brandenburg and Pomerania.
The original Treaty on Conventional Armed Forces in Europe (CFE) was negotiated and concluded during the last years of the Cold War and established comprehensive limits on key categories of conventional military equipment in Europe and mandated the destruction of excess weaponry. The treaty proposed equal limits for the two "groups of states-parties", the North Atlantic Treaty Organization (NATO) and the Warsaw Pact. In 2007, Russia "suspended" its participation in the treaty, and on 10 March 2015, citing NATO's alleged de facto breach of the Treaty, Russia formally announced it was "completely" halting its participation in it as of the next day. On 7 November 2023, Russia withdrew from the treaty, and in response the United States and its NATO allies suspended their participation in the treaty.
The Collective Security Treaty Organization (CSTO) is an intergovernmental military alliance in Eurasia consisting of six post-Soviet states: Armenia, Belarus, Kazakhstan, Kyrgyzstan, Russia, and Tajikistan, formed in 2002. The Collective Security Treaty has its origins in the Soviet Armed Forces, which was replaced in 1992 by the United Armed Forces of the Commonwealth of Independent States, and was then itself replaced by the successor armed forces of the respective independent states.
The United States and Russia maintain one of the most important, critical, and strategic foreign relations in the world. Both nations have shared interests in nuclear safety and security, nonproliferation, counterterrorism, and space exploration. Due to the Russian invasion of Ukraine, relations became very tense after the United States imposed sanctions against Russia. Russia placed the United States on a list of "unfriendly countries", along with South Korea, Taiwan, European Union members, NATO members, Switzerland, Australia, New Zealand, Singapore, Micronesia, Japan and Ukraine.
NATO is a military alliance of thirty-two European and North American countries that constitutes a system of collective defense. The process of joining the alliance is governed by Article 10 of the North Atlantic Treaty, which allows for the invitation of "other European States" only and by subsequent agreements. Countries wishing to join must meet certain requirements and complete a multi-step process involving political dialogue and military integration. The accession process is overseen by the North Atlantic Council, NATO's governing body. NATO was formed in 1949 with twelve founding members and has added new members ten times. The first additions were Greece and Turkey in 1952. In May 1955, West Germany joined NATO, which was one of the conditions agreed to as part of the end of the country's occupation by France, the United Kingdom, and the United States, prompting the Soviet Union to form its own collective security alliance later that month. Following the end of the Franco regime, newly democratic Spain chose to join NATO in 1982.
The foreign policy of Vladimir Putin concerns the policies of the Russian Federation's president Vladimir Putin with respect to other nations. He has held the office of the President previously from 2000 to 2008, and reassumed power again in 2012 and has been President since.
NATO 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. 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.
Relations between Ukraine and the North Atlantic Treaty Organization (NATO) started in 1991 following Ukraine's independence after the dissolution of the Soviet Union. Ukraine-NATO ties gradually strengthened during the 1990s and 2000s, and Ukraine aimed to eventually join the alliance. Although co-operating with NATO, Ukraine remained a neutral country. After it was attacked by Russia in 2014, Ukraine has increasingly sought NATO membership.
The "nuclear umbrella" is a guarantee by a nuclear weapons state to defend a non-nuclear allied state. The context is usually the security alliances of the United States with Australia, Japan, South Korea, the North Atlantic Treaty Organization and the Compact of Free Association. Those alliances were formed because of the Cold War and the Soviet Union. For some countries, it was an alternative to acquiring nuclear weapons themselves; other alternatives include regional nuclear-weapon-free zones or nuclear sharing.
Relations between the NATO military alliance and the Russian Federation were established in 1991 within the framework of the North Atlantic Cooperation Council. In 1994, Russia joined the Partnership for Peace program, and on 27 May 1997, the NATO–Russia Founding Act (NRFA) was signed at the 1997 Paris NATO Summit in France, enabling the creation of the NATO–Russia Permanent Joint Council (NRPJC). Through the early part of 2010s NATO and Russia signed several additional agreements on cooperation. The NRPJC was replaced in 2002 by the NATO-Russia Council (NRC), which was established in an effort to partner on security issues and joint projects together.
NATO maintains foreign relations with many non-member countries across the globe. NATO runs a number of programs which provide a framework for the partnerships between itself and these non-member nations, typically based on that country's location. These include the Euro-Atlantic Partnership Council and the Partnership for Peace.
In March and April 2021, prior to the 2022 Russian invasion of Ukraine, the Russian Armed Forces began massing thousands of personnel and military equipment near Russia's border with Ukraine and in Crimea, representing the largest mobilisation since the illegal annexation of Crimea in 2014. This precipitated an international crisis due to concerns over a potential invasion. Satellite imagery showed movements of armour, missiles, and heavy weaponry towards the border. The troops were partially withdrawn by June 2021, though the infrastructure was left in place. A second build-up began in October 2021, this time with more soldiers and with deployments on new fronts; by December over 100,000 Russian troops were massed around Ukraine on three sides, including Belarus from the north and Crimea from the south. Despite the Russian military build-ups, Russian officials from November 2021 to 20 February 2022 repeatedly denied that Russia had plans to invade Ukraine.
Armenia and the North Atlantic Treaty Organization (NATO) have maintained a formal relationship since 1992, when Armenia joined the North Atlantic Cooperation Council. Armenia officially established bilateral relations with NATO in 1994 when it became a member of NATO's Partnership for Peace (PfP) programme. In 2002, Armenia became an Associate Member of the NATO Parliamentary Assembly.
In the context of the enlargement of NATO, Article 10 of the North Atlantic Treaty is the origin for the April 1999 statement of a "NATO open door policy". The open door policy requires a consensus in favour of countries applying to join NATO, as all member states must ratify the protocol enabling a new country to become a member of NATO. The open door policy "is aimed at promoting stability and cooperation".
The controversy in Russia regarding the legitimacy of eastward NATO expansion relates to the aftermath of the Revolutions of 1989, when the fall of Soviet-allied communist states to opposition parties brought European spheres of influence into question. US documents claim that agreement on non-expansion of NATO to Eastern Europe took place orally and the alliance violated it with its expansion while the leaders of the alliance claim that no such promise was made and that such a decision could only be made in writing. Soviet President Mikhail Gorbachev, who participated in the 1990 negotiations, subsequently spoke out about the existence of a "guarantee of non-expansion of NATO to the east" inconsistently, confirming its existence in some interviews and refuting in others. Among academic researchers, opinions on the existence or absence of a non-extension agreement also differ.
