North Atlantic Treaty Organization
NATO (Concise Encyclopedia)
International military alliance created to defend western Europe against a possible Soviet invasion. A 1948 collective-defense alliance between Britain, France, The Netherlands, Belgium, and Luxembourg was recognized as inadequate to deter Soviet aggression, and in 1949 the U.S. and Canada agreed to join their European allies in an enlarged alliance. A centralized administrative structure was set up, and three major commands were established, focused on Europe, the Atlantic, and the English Channel (disbanded in 1994). The admission of West Germany in 1955 led to the Soviet Union's creation of the opposing Warsaw Treaty Organization, or Warsaw Pact. France withdrew from military participation in 1966. Since NATO ground forces were smaller than those of the Warsaw Pact, the balance of power was maintained by superior weaponry, including intermediate-range nuclear weapons. After the Warsaw Pact's dissolution and the end of the Cold War in 1991, NATO withdrew its nuclear weapons and attempted to transform its mission. It involved itself in the Balkan conflicts of the 1990s. Article 5 of the North Atlantic Treaty stated that an attack on one signatory would be regarded as an attack on the rest. This article was first invoked in 2001 in response to the terrorist September 11 attacks against the U.S. Additional countries joined NATO in 1999, 2004, and 2009 to bring the number of full members to 28. In 2009 France announced its plan to rejoin NATO's integrated military command.
