Strategic Arms Limitations Talks between the Soviet Union and the United State were aimed at limiting missile systems and other strategic armaments. The first round of talks (SALT I) was held from 1969-1972, and the second from 1972-1979. SALT I concluded on May 20, 1971, when the ABM Treaty and the Interim Agreement limiting strategic offensive arms were signed. The SALT II Treaty was signed but was not ratified by either country.
