After graduation from law school, Bennett joined the
Foreign Service in 1941. He served as a
United States Army intelligence officer during
World War II. From 1951 to 1954, Bennett was Deputy Director to the Office of South American Affairs. From 1954 to 1955, he studied at the
National War College and for two years after, he served as Special Assistant to the
Under Secretary of State for Political Affairs. From 1957 to 1964, he acted as Counselor and Minister at the U.S. Embassies in
Rome, Italy, in
Vienna, Austria, and in
Athens, Greece. President
Lyndon Johnson appointed him Ambassador to the Dominican Republic after the previous Ambassador,
John Bartlow Martin, resigned after the
Kennedy assassination on the very day in which
Juan Bosch, then President of the Dominican Republic, was toppled in a
coup d'etat. While Ambassador, Bennett "advised President Johnson and members of Congress that the revolt was led by Communists" and recommended President Johnson intervene with United States troops during the
Dominican Civil War. Reportedly "seeking relief from the tropical heat of the Dominican Republic," He served in that role until
Richard Nixon became president in 1969 and he was succeeded by
Ridgway B. Knight, who up until that point was the
Ambassador to Belgium.
Later career After retiring in 1985 he served as adjunct professor of international law at the
University of Georgia. From 1991 to 1992, he served as president of the
Atlantic Treaty Association. ==Personal life==
