Article response by Ken Hughes, a research fellow with the Miller Center's Presidential Recordings Program ... I'm glad you mentioned Richard Nixon's responsibility for losing Vietnam in "Criticism of War Policy is Patriotic." My study of the Nixon White House tapes ... shows that Nixon understood that his settlement with Hanoi doomed South Vietnam. I've turned my research into a documentary miniseries, Fatal Politics: The Nixon Tapes, Vietnam & the Biggest Republican Presidential Landslide.
