First of all, it would have been absolutely impossible to find a actor who looked and acted more like Harry Truman that Kenneth Walsh. Second, the most fascinating aspects of this movie relate to what was happening in Japan at the closing of the war. The idea that a majority of the military officers would have rather seen Japan cease to exist as a people than to surrender really provides some counter-balance to all of the recent revisionist history that claims that Japan was in the process of surrendering and that the U.S. used the A-bomb simply to avenge earlier Japanese treachery. "Hiroshima" is historical film-making at its best.
