戦略兵器制限交渉
The Strategic Arms Limitation Talks (SALT) between the United States and Soviet Union in the late 1960s/early 1970s led to further weapons control agreements. The SALT I talks led to the Anti-Ballistic Missile Treaty and an "Interim Strategic Arms Limitation Agreement" (see SALT I), both in 1972. The SALT II talks started in 1972 leading to agreement in 1979. Due to the Soviet Union's invasion of Afghanistan the United States never ratified the treaty, but the agreement was honoured by both sides.
