"Kissinger is one of the best known diplomats of the 20th century, but also a controversial figure.
He was secretary of state to Presidents Richard M. Nixon and Gerald R. Ford. He won the Nobel Peace Prize in 1973 with North Vietnam's Le Duc Tho for cease-fire negotiations during the Vietnam war. Kissinger also made a determined peacemaking effort in the Middle East and made repeated trips to the region. But he has also been called a war criminal by his harshest critics, for the role he played in Vietnam and other hot spots, working at times with corrupt governments in pursuit of U.S. interests."
