Author Christian Appy joins us to discuss the continuing aftermath of the Vietnam War

  This month marks the 50th anniversary of President Lyndon Johnson?'s decision to begin the massive escalation of the Vietnam War. The war, which ended in April 1975, bitterly divided the United States between those who saw a need to suppress the spread of communism and those who challenged the morality, legality and practically of fighting in a distant southeast Asian country. Vietnam?'s impact is still being felt today, especially in the two recent wars in Iraq and Afghanistan. Christian Appy, author and professor of history at the University of Massachusetts-Amherst, takes a look at the Vietnam War and its aftermath in his new book American Reckoning: The Vietnam War and Our National Identity. He joins us to discuss the war and his book.
