Salt deals with strategic objectives and doctrine, weapons systems, evolving technology, and is discussed in esoteric terminology. Decisions, however, are made by political leaders in the United States and the USSR in political contexts. Of the four agreements concluded at SALT I, the Anti-Ballistic Missile (ABM) Treaty is clearly the most important. Odier agreements are the Interim Agreement on Limitation of Strategic Offensive Systems; the Accident Measures Agreement; and the revised Hot Line Agreement.
