During the Presidencies of both Richard Nixon and
Gerald Ford, linkage diplomacy was used as a key foreign policy measure. It was particularly aimed at the Soviet Union. Henry Kissinger, who was Nixon's
National Security Advisor, said that the aim of this policy was to "free [American] foreign policy from oscillations between overextension and isolation and to ground it in a firm conception of the national interest." 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. Kissinger objected the intervention from Congress as he believed foreign issues are better resolved quietly than publicly in Congress. The success of quiet diplomacy can be seen in the following fact: in 1968 only 400 Jews were allowed to emigrate, but in 1973, nearly 35,000 were allowed to emigrate. Nixon and Kissinger were secretive in their policymaking. This was because they were suspicious of the
bureaucracy. Decisions were made without the knowledge of
William Rogers, who was the secretary of State at the time and responsible for the management of US diplomacy. Congress also grew suspicious and played a role in foreign policy as well. This secrecy and conflicting ideas made it difficult to gain concessions and make progress in foreign policy. == Jimmy Carter era (1977–1981) ==
