Guest Michel Paradis on his fascinating new book "Last Mission To Tokyo" and how the ingenuity and success of Doolittle's raid marked a crucial turning point in America's war in the Pacific.  Paradis argues that Jimmy Doolittle and his men's bombing raid on Tokyo in early 1942 marked a crucial turning point against Japan in the early days of America's involvement in World War II.  This horrific psychological blow on Japan caused their Imperial forces to reverse strategy and play defense, perhaps even saving the American West Coast from invasion.
