What is a war criminal? Was not war itself a crime against God and humanity, and, therefore, were not all those who sanctioned, engineered, and conducted wars, war criminals? War criminals are not confined to the Axis Powers alone. Roosevelt and Churchill are no less war criminals than Hitler and Mussolini. England, America and Russia have all of them got their hands dyed more or less red - not merely Germany and Japan.
