  NATO was established on 4 April 1949 by 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.
  
  Four new members joined during the Cold War: Greece (1952), Turkey (1952), West Germany (1955) and Spain (1982). Following the dissolution of the Soviet Union, many former Warsaw Pact and post-Soviet states sought membership. In 1990, the territory of the former East Germany was added with the reunification of Germany. At the 1999 Washington summit, Hungary, Poland, and the Czech Republic officially joined, and NATO issued new guidelines for membership, with individualized " Membership Action Plans ". These plans governed the addition of new members: Bulgaria, Estonia, Latvia, Lithuania, Romania, Slovakia, and Slovenia in 2004, Albania and Croatia in 2009, Montenegro in 2017, and North Macedonia in 2020. Finland and Sweden are the newest members, joining on 4 April 2023 and 7 March 2024 respectively, spurred on by Russia's invasion of Ukraine.
  
  Ukraine's relationship with NATO began with the NATO–Ukraine Action Plan in 2002. In 2010, under President Viktor Yanukovych, Ukraine re-affirmed its non-aligned status and renounced aspirations of joining NATO. During the 2014 Ukrainian Revolution, Russia occupied Crimea and supported armed separatists in eastern Ukraine. As a result, in December 2014 Ukraine's parliament voted to end its non-aligned status, and in 2019 it enshrined the goal of NATO membership in the Constitution. At the June 2021 Brussels Summit, NATO leaders affirmed that Ukraine would eventually join the Alliance, and supported Ukraine's right to self-determination without interference. In late 2021, there was another massive Russian military buildup near Ukraine's borders. On 30 November, Russian president Putin said Ukraine joining NATO, and the deployment of missile defense systems or long-range missiles in Ukraine, would be crossing a red line. However, there were no such plans to deploy missiles in Ukraine. The Russian Foreign Ministry drafted a treaty that would forbid Ukraine or any former Soviet state from ever joining NATO. Secretary-General Stoltenberg replied that the decision is up to Ukraine and NATO members, adding "Russia has no veto, Russia has no say, and Russia has no right to establish a sphere of influence to try to control their neighbors". NATO offered to improve communications with Russia and discuss missile placements and military exercises, as long as Russia withdrew troops from Ukraine's borders. Instead, Russia invaded Ukraine in February 2022. Ukraine applied for NATO membership in September 2022 after Russia proclaimed it had annexed the country's southeast.
  
  Georgia was promised "future membership" during the 2008 summit in Bucharest, but US president Barack Obama said in 2014 that the country was not "currently on a path" to membership.
  
  Russia continued to politically oppose further expansion, seeing it as inconsistent with informal understandings between Soviet leader Mikhail Gorbachev and European and US negotiators that allowed for a peaceful German reunification. A June 2016 Levada Center poll found that 68 percent of Russians think that deploying NATO troops in the Baltic states and Poland – former Eastern bloc countries bordering Russia – is a threat to Russia. In contrast, 65 percent of Poles surveyed in a 2017 Pew Research Center report identified Russia as a "major threat", with an average of 31 percent saying so across all NATO countries, and 67 percent of Poles surveyed in 2018 favour US forces being based in Poland. Of non- CIS Eastern European countries surveyed by Gallup in 2016, all but Serbia and Montenegro were more likely than not to view NATO as a protective alliance rather than a threat. A 2006 study in the journal Security Studies argued that NATO enlargement contributed to democratic consolidation in Central and Eastern Europe. China also opposes further expansion.
