NATO
Origin, Structure, and Article 5
The North Atlantic Treaty Organization (NATO) is a military alliance established by the Washington Treaty of 1949, originally formed by 12 founding members to provide collective defence against the Soviet bloc during the Cold War. Its core principle, Article 5 of the Washington Treaty, holds that an armed attack against one or more member states shall be considered an attack against all of them, obligating collective response.
- Founded: 4 April 1949 (Washington Treaty); headquartered in Brussels, Belgium
- Current membership: 32 states, following Finland's accession (2023) and Sweden's accession (7 March 2024) — both a departure from decades of military non-alignment
- Article 5 (collective defence) has been formally invoked only once, after the 11 September 2001 attacks on the United States
- Decision-making is by consensus in the North Atlantic Council, NATO's principal political decision-making body
