It’s well known that as the Truman White House made plans to use the first atomic bombs against Japan in the summer of 1945, a large group of atomic scientists, many of whom had worked on the bomb project, raised their voices, or at least their names, in protest.

One of the great "What if?" questions of the 20th century is how America would have been different if Henry Wallace rather than Harry Truman had succeeded Franklin Roosevelt in the White House. Filmmaker Oliver Stone has revived this debate in his current ten-part Showtime series, "The Untold History of the United States," and his new book (written with historian Peter Kuznick) of the same name.
