The Strategic Arms Limitation Talks II (SALT II) replaced the Interim Agreement. The Treaty came close to entering into force, but when U.S. President Ronald Reagan declared that the Soviet Union violated its political commitment to the Treaty, Reagan decided an interim framework, obligating the restraint from undercutting existing arms agreements, would work for the United States.

SALT II would have called for numerical limits on missiles, bans on certain missiles, definitions of limited systems, and verifications. Actions by the United States and the Soviet Union would have been verified through photo-reconnaissance satellites. The Treaty would have been in effect through 1985.
