Reduction in armaments by one or more nations. Arms reductions may be imposed by a war's victors on the defeated (as happened after Germany's defeat in World War I). Bilateral disarmament agreements may apply to a specific area (such an agreement has kept the Great Lakes weapon-free since 1817). The term is most commonly used for multilateral reduction and limitation agreements, particularly in the context of nuclear weapons. See also arms control.
