 This famous propaganda piece, used as a U.S. Army training film in WWII before theatrical release, asks  why we fight.  The answer compares the  free  and  slave  worlds. Included: development of dictatorships in Italy, Germany and Japan, while anti-militarism and isolationism rise in the USA; a look at enemy propaganda; and the first acts of aggression. Walter Huston narrates a combination of archival footage, maps, and other graphics.
