Strategic Arms Limitation Talks in the context of Anti-Ballistic Missile Treaty

Richard Nixon's tenure as the 37th president of the United States began with his first inauguration on January 20, 1969, and ended when he resigned on August 9, 1974, in the face of almost certain impeachment and removal from office, the only U.S. president ever to do so. He was succeeded by Gerald Ford, whom he had appointed vice president after Spiro Agnew became embroiled in a separate corruption scandal and was forced to resign. Nixon, a prominent member of the Republican Party from California who previously served as vice president for two terms under president Dwight D. Eisenhower from 1953 to 1961, took office following his narrow victory over Democratic incumbent vice president Hubert Humphrey and American Independent Party nominee George Wallace in the 1968 presidential election. Four years later, in the 1972 presidential election, he defeated Democratic nominee George McGovern, to win re-election in a landslide. Although he had built his reputation as a very active Republican campaigner, Nixon downplayed partisanship in his 1972 landslide re-election.

Nixon's primary focus while in office was on foreign affairs. He focused on détente with the People's Republic of China and the Soviet Union, easing Cold War tensions with both countries. As part of this policy, Nixon signed the Anti-Ballistic Missile Treaty and SALT I, two landmark arms control treaties with the Soviet Union. Nixon promulgated the Nixon Doctrine, which called for indirect assistance by the United States rather than direct U.S. commitments as seen in the ongoing Vietnam War. After extensive negotiations with North Vietnam, Nixon withdrew the last U.S. soldiers from South Vietnam in 1973, ending the military draft that same year. To prevent the possibility of further U.S. intervention in Vietnam, Congress passed the War Powers Resolution over Nixon's veto.

Zbigniew "Zbig" Kazimierz Brzeziński (/ˈzbɪɡnjɛf brəˈzɪnski/ , Polish: [ˈzbiɡɲɛf kaˈʑimjɛʐ‿bʐɛˈʑij̃skʲi] ; March 28, 1928 – May 26, 2017) was a Polish-American diplomat and political scientist. He served as a counselor to Lyndon B. Johnson from 1966 to 1968 and was Jimmy Carter's National Security Advisor from 1977 to 1981. As a scholar, Brzeziński belonged to the realist school of international relations, standing in the geopolitical tradition of Halford Mackinder and Nicholas J. Spykman, while elements of liberal idealism have also been identified in his outlook. Brzeziński was the primary organizer of The Trilateral Commission.

Major foreign policy events during his time in office included the normalization of relations with the People's Republic of China (and the severing of ties with the Republic of China on Taiwan); the signing of the second Strategic Arms Limitation Treaty (SALT II) with the Soviet Union; the brokering of the Camp David Accords between Egypt and Israel; the overthrow of the US-friendly Mohammad Reza Pahlavi and the start of the Iranian Revolution; the United States' encouragement of dissidents in Eastern Europe and championing of human rights in order to undermine the influence of the Soviet Union; supporting the Afghan mujahideen against the Soviet-backed Democratic Republic of Afghanistan and, ultimately, Soviet troops during the Soviet–Afghan War; and the signing of the Torrijos–Carter Treaties relinquishing U.S. control of the Panama Canal after 1999.
