The landmark pricing agreement that marked the beginning of serious negotiations between the U.S. and Soviet Union during the Cold War was the SALT I treaty, specifically the Strategic Arms Limitation Talks. Initiated in the late 1960s, these negotiations aimed to curtail the arms race between the superpowers by placing limits on the number of nuclear weapons and delivery systems each could possess. The agreement reflected a critical shift towards diplomacy, as both nations sought to manage their rivalry and avert direct military conflict, setting a precedent for future arms control efforts.
