The two roundtables and agreements were the points OF SALT I and SALT II. Signed in 1972, it was in force for the next 30 years.  In 1997, five years after the dissolution of the Soviet Union, four former Soviet republics agreed with the United States to play the role of the USSR in the treaty.
In June 2002, the United States withdrew from the treaty, which led to its termination. Negotiations on the FN treaty showed progress when Mikhail Gorbachev became Soviet Secretary General in March 1985. In the fall of the same year, the Soviet Union presented a plan to balance the number of SS-20 warheads with the increasing number of medium-range allied warheads in Europe. The United States expressed interest in the Soviet proposal and the scope of the negotiations was extended in 1986 to all U.S. and Soviet medium-range missiles around the world. President Ronald Reagan and Gorbachev began to move forward with the momentum of these talks towards a comprehensive agreement on the elimination of medium-range missiles. Their efforts culminated in the signing of the FN Treaty on 8 December 1987, and the treaty entered into force on 1 June 1988.
