NATO

The North Atlantic Treaty Organization (NATO, /ˈnt/; French: Organisation du traité de l'Atlantique nord, OTAN), also called the North Atlantic Alliance, is an intergovernmental military alliance between 30 member states – 28 European and two North American. Established in the aftermath of World War II, the organization implements the North Atlantic Treaty, which was signed in Washington, D.C., on 4 April 1949.[3][4] NATO is a system of collective security: 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 perceived threat posed by the Soviet Union. The alliance remained in place after the dissolution of the Soviet Union and has been involved in military operations in the Balkans, the Middle East, South Asia, and Africa.

NATO's main headquarters are located in Brussels, Belgium, while NATO's military headquarters are near Mons, Belgium. The alliance has targeted deployments of their NATO Response Force in Eastern Europe, and the combined militaries of all NATO members include around 3.5 million soldiers and personnel.[5] Their combined military spending as of 2020 constituted over 57 percent of the global nominal total.[6] Members have agreed that their aim is to reach or maintain the target defence spending of at least two percent of their GDP by 2024.[7][8]

NATO formed with twelve founding members, and has added new members eight times, most recently when North Macedonia joined the alliance in March 2020. Following the acceptance of their applications for membership in June 2022, Finland and Sweden are anticipated to become the 31st and 32nd members, with their Accession Protocols to the North Atlantic Treaty now in the process of being ratified by the existing members.[9] NATO currently also recognizes Bosnia and Herzegovina, Georgia, and Ukraine as aspiring members.[3] Enlargement has led to tensions with non-member Russia, which is one of the twenty additional countries that participate in NATO's Partnership for Peace programme. Another nineteen countries are involved in institutionalized dialogue programmes with NATO.
