戦略兵器制限交渉
Following the signing of the Strategic Arms Limitation Talks (SALT) agreement in 1972, both the US and the Soviet Union agreed to practise mutual restraint. The terms of the agreement were vague. This meant that Nixon and Kissinger interpreted it as a justification of their own actions. As a result of this, part of this administrations perception of linkage was to convince Soviet leaders that they would have motivation for moderation, and also punishment for a contradiction of the previous agreements they had signed.
