You'll hear an extended conversation with Lewis Sorley about his much-discussed book "A Better War: The Unexamined Victories and Final Tragedy of America's Last Years in Viet Nam," which closely examines the war from 1968 on. It's Sorley's contention that America had begun to radically reshape how it was conducting the war and began seeing very positive results, and that we might have more successfully resolved the conflict had we not withdrawn in the way we did. The second half of the conversation will include some commentary on our current involvement in both Iraq and Afghanistan and of how those conflicts compare with Viet Nam.
