Glossary: Anti-Ballistic Missile Treaty (ABM Treaty)

A 1972 agreement limiting deployment of United States and Soviet anti-ballistic missile (ABM) systems. A protocol signed in 1974 limited each party to a single ABM system deployment area. In 1996 the United States and Russia negotiated to modify the terms of the treaty in order to permit testing of technology against non-intercontinental delivery systems.
