Henry Kissinger

Context: Kissinger underwent basic training at Camp Croft in Spartanburg, South Carolina. On June 19, 1943, while stationed in South Carolina, at the age of 20 years, he became a naturalized U.S. citizen. The army sent him to study engineering at Lafayette College, Pennsylvania, but the program was canceled, and Kissinger was reassigned to the 84th Infantry Division. There, he made the acquaintance of Fritz Kraemer, a fellow Jewish immigrant from Germany who noted Kissinger's fluency in German and his intellect, and arranged for him to be assigned to the military intelligence section of the division. Kissinger saw combat with the division, and volunteered for hazardous intelligence duties during the Battle of the Bulge.  During the American advance into Germany, Kissinger, only a private, was put in charge of the administration of the city of Krefeld, owing to a lack of German speakers on the division's intelligence staff. Within eight days he had established a civilian administration. Kissinger was then reassigned to the Counter Intelligence Corps (CIC), where he became a CIC Special Agent holding the enlisted rank of sergeant. He was given charge of a team in Hanover assigned to tracking down Gestapo officers and other saboteurs, for which he was awarded the Bronze Star. In June 1945, Kissinger was made commandant of the Bensheim metro CIC detachment, Bergstrasse district of Hesse, with responsibility for de-Nazification of the district. Although he possessed absolute authority and powers of arrest, Kissinger took care to avoid abuses against the local population by his command.  In 1946, Kissinger was reassigned to teach at the European Command Intelligence School at Camp King and, as a civilian employee following his separation from the army, continued to serve in this role.  Henry Kissinger received his AB degree summa cum laude, Phi Beta Kappa in political science from Harvard College in 1950, where he lived in Adams House and studied under William Yandell Elliott. He received his MA and PhD degrees at Harvard University in 1951 and 1954, respectively. In 1952, while still a graduate student at Harvard, he served as a consultant to the director of the Psychological Strategy Board. His doctoral dissertation was titled "Peace, Legitimacy, and the Equilibrium (A Study of the Statesmanship of Castlereagh and Metternich)".  Kissinger remained at Harvard as a member of the faculty in the Department of Government and, with Robert R. Bowie, co-founded the Center for International Affairs in 1958 where he served as associate director. In 1955, he was a consultant to the National Security Council's Operations Coordinating Board. During 1955 and 1956, he was also study director in nuclear weapons and foreign policy at the Council on Foreign Relations. He released his book Nuclear Weapons and Foreign Policy the following year. From 1956 to 1958 he worked for the Rockefeller Brothers Fund as director of its Special Studies Project. He was director of the Harvard Defense Studies Program between 1958 and 1971. He was also director of the Harvard International Seminar between 1951 and 1971. Outside of academia, he served as a consultant to several government agencies and think tanks, including the Operations Research Office, the Arms Control and Disarmament Agency, Department of State, and the RAND Corporation.  Keen to have a greater influence on U.S. foreign policy, Kissinger became foreign policy advisor to the presidential campaigns of Nelson Rockefeller, supporting his bids for the Republican nomination in 1960, 1964, and 1968. After Richard Nixon won the presidency in 1968, he made Kissinger National Security Advisor.  As National Security Advisor under Nixon, Kissinger pioneered the policy of detente with the Soviet Union, seeking a relaxation in tensions between the two superpowers. As a part of this strategy, he negotiated the Strategic Arms Limitation Talks (culminating in the SALT I treaty) and the Anti-Ballistic Missile Treaty with Leonid Brezhnev, General Secretary of the Soviet Communist Party. Negotiations about strategic disarmament were originally supposed to start under the Johnson Administration but were postponed in protest upon the invasion by Warsaw Pact troops of Czechoslovakia in August 1968.  Kissinger sought to place diplomatic pressure on the Soviet Union. He made two trips to the People's Republic of China in July and October 1971 (the first of which was made in secret) to confer with Premier Zhou Enlai, then in charge of Chinese foreign policy. According to Kissinger's book, "The White House Years" and "On China", the first secret China trip was arranged through Pakistani and Romanian diplomatic and Presidential involvement, as there were no direct communication channels between the states. His trips paved the way for the groundbreaking 1972 summit between Nixon, Zhou, and Communist Party of China Chairman Mao Zedong, as well as the formalization of relations between the two countries, ending 23 years of diplomatic isolation and mutual hostility. The result was the formation of a tacit strategic anti-Soviet alliance between China and the United States.  While Kissinger's diplomacy led to economic and cultural exchanges between the two sides and the establishment of Liaison Offices in the Chinese and American capitals, with serious implications for Indochinese matters, full normalization of relations with the People's Republic of China would not occur until 1979, because the Watergate scandal overshadowed the latter years of the Nixon presidency and because the United States continued to recognize the government of Taiwan.  In September 1989, the Wall Street Journal's John Fialka disclosed that Kissinger took a direct economic interest in US-China relations in March 1989 with the establishment of China Ventures, Inc., a Delaware limited partnership, of which he was chairman of the board and chief executive officer. A US$75 million investment in a joint venture with the Communist Party government's primary commercial vehicle at the time, China International Trust & Investment Corporation (CITIC), was its purpose. Board members were major clients of Kissinger Associates. Kissinger was criticised for not disclosing his role in the venture when called upon by ABC's Peter Jennings to comment the morning after the June 4, 1989, Tiananmen crackdown. Kissinger's position was generally supportive of Deng Xiaoping's clearance of the square and he opposed economic sanctions. CANNOTANSWER
