The strategic Arms Limitation Talks II (SALT II) replaced the interim agreement. The treaty was about to enter into force, but when U.S. President Ronald Reagan declared that the Soviet Union was violating its political commitment to the treaty, Reagan decided to establish an interim framework that required limiting the under-employment of existing arms agreements. In order to promote existing agreements between the parties on the limitation and reduction of strategic weapons, the parties will continue to seek measures to strengthen strategic stability to reduce and prevent the risk of nuclear war, including by striving to limit strategic offensive weapons that most destabilize the strategic balance and by taking steps to reduce and prevent the risk of a surprise attack. In 1984 and 1985, President Reagan declared that the Soviet Union had breached its political obligation to abide by the SALT II Treaty. However, President Reagan decided that an interim framework of mutual restraint would remain in the interest of the United States and stated in June 1985 that the United States would continue to forego undermining existing strategic arms agreements as the Soviet Union showed comparable restraint and provided for the Soviet Union to actively conclude arms reduction agreements during the nuclear and space talks in Geneva. In May 1982, President Reagan declared that he would do nothing to undermine the salts agreements as long as the Soviet Union shows the same restraint. The Soviet Union once again declared itself ready to comply with the un ratified treaty. Strategic Arms Limitation Talks (SALT), negotiations between the United States and the Soviet Union to limit the manufacture of strategic missiles capable of carrying nuclear weapons.

The first agreements, known as SALT I and SALT II, were signed in 1972 and 1979 by the United States and the Union of Soviet Socialist Republics and aimed to limit the arms race of strategic (long-range or intercontinental) nuclear-armed ballistic missiles. For the first time proposed by U.S. President Lyndon B. Johnson in 1967, strategic arms limitation talks were agreed by the two superpowers in the summer of 1968, and in November 1969 comprehensive negotiations began. On May 26, 1986, President Reagan stated that he had re-examined the status of U.S. interim policy and that the Soviet Union, as it had demonstrated in three detailed reports to Congress, had failed to live up to its political commitment to abide by the Salts agreements, including the SALT II Treaty, and that the Soviet Union had also not expressed its willingness to join a genuine mutual reserve.
