Three figures of Dr. Henry Kissinger lurk in the jungle of Indochina in Herblock’s cartoon with a title alluding to the British explorer Dr. David Livingstone. As President Richard Nixon’s national security advisor in 1972, Kissinger pursued détente—easing tensions with the Soviet Union and China—and ending the Vietnam War. His sometimes secret negotiations took place in Paris, Peking (now Beijing), and Moscow. His efforts furthered finalization of the Paris Peace Accords in January 1973, bringing ceasefires in Vietnam.
