Salt I: An agreement signed in 1972 by U.S. President Richard M. Nixon and Soviet leader Leonid Brezhnev after the first round of Strategic Arms Limitations Talks (SALT I), held from 1969-72. It consisted of the Anti-Ballistic Missile Treaty and an Interim Agreement on the Limitation of Strategic Offensive Arms.
Salt 2: agreement dealing with limitations and guidelines for nuclear weapons. The treaty, which never formally went into effect, proved to be one of the most controversial U.S.-Soviet agreements of the Cold War. The SALT-II agreement was the result of many nagging issues left over from the successful SALT-I treaty of 1972.
In June 1979, Carter and Brezhnev met in Vienna and signed the SALT-II agreement. The treaty basically established numerical equality between the two nations in terms of nuclear weapons delivery systems. It also limited the number of MIRV missiles (missiles with multiple, independent nuclear warheads). In truth, the treaty did little or nothing to stop, or even substantially slow down, the arms race. Nevertheless, it met with unrelenting criticism in the United States. The treaty was denounced as a "sellout" to the Soviets, one that would leave America virtually defenseless against a whole range of new weapons not mentioned in the agreement. Even supporters of arms control were less than enthusiastic about the treaty, since it did little to actually control arms. Debate
