Henry Kissinger was a German-born American political scientist, bureaucrat and diplomat who served America as National Security Advisor and later as Secretary of State under the presidency of Richard Nixon and was awarded the Nobel Peace Prize in 1973. As National Security Advisor and Secretary of States, Kissinger adopted the policy of détente in foreign affairs which improved America's deteriorating relations with the world's two super powers - Soviet Union and China. However, his landmark achievement was a ceasefire with Vietnam which brought an end to the long time war between the two countries for which he was awarded the honorary Nobel Peace Prize in 1973. He was one of the few officials of President Nixon to come out with a clean image from the widely condemned Watergate scandal and despite several accusations and impeachments, has continued to hold important positions in the American Government. Kissinger was Chairman of Kissinger Associates Inc., an international consulting firm. As an author, he published numerous books as well as articles on United States foreign policy. His columns appeared in leading American and International newspapers.
