Henry Kissinger, the toweringly influential former secretary of state who earned a reputation as a sagacious diplomat but drew international condemnation and accusations of war crimes for his key role in widening the American presence in Vietnam and the U.S. bombing of Cambodia, died Wednesday. He was 100. Kissinger, a Jewish refugee from Nazi Germany, reached the pinnacle of the American political establishment and in turn became an unlikely household name. He was secretary of state and national security adviser under two Republican presidents, Richard Nixon and Gerald Ford, and advised powerful leaders in both American political parties for decades.
