Henry Kissingers involvement with Vietnam started before he was Nixons National Security Advisor. While at Harvard, Kissinger was a consultant on foreign policy to both the White House and State Department and in a 1973 peace agreement, Kissinger helped mediate between Washington and Hanoi. In this interview Kissinger recalls the period before he joined the Nixon White House and how he did not question the United States involvement in Vietnam. In 1965, Kissinger travelled to Vietnam and saw that the war was not winnable in the way it was currently being conducted. Moreover, he had doubts as to whether or not South Vietnam could stand on their own once the United States left. He also describes his impression of Le Duc Tho as someone whose goal was to break the morale and spirit of the American people and partake in psychological warfare. Kissinger continues by stating that Vietnam still has an effect on American policy.
