The agreement between the US and the Soviet Union to limit the production of some nuclear weapons was called the Strategic Arms Limitation Talks (SALT). The first round, SALT I, resulted in the Anti-Ballistic Missile Treaty and an interim agreement on the limitation of strategic offensive arms in 1972. SALT II followed in 1979, aiming to further reduce the number of nuclear weapons, though it was never ratified by the US Senate. These agreements were crucial in the effort to control the arms race during the Cold War.
