Kennedy inherited an ill-conceived, poorly executed invasion of Cuba that failed miserably and set in motion the events that put the U.S. and the Soviet Union on a collision course that nearly started a war that would have enveloped much of the world. Newt talks with best-selling author Jeff Shaara about his new book, "The Shadow of War," which focuses on the Cuban Missile Crisis. Shaara explains his approach to writing historical novels, emphasizing the importance of character development and extensive research.
