On December 7, 1941, an aggressive empire that indoctrinated its soldiers in the divine nature of its bloody conquests attacked the USA at Pearl Harbor. America did not bow down to the Empire of the Sun. The USA brought its unparalleled military-industrial complex to bear upon the foe, defeating Japan and ultimately liberating untold millions in Asia from slavery. Without this determined effort, China, Korea, Vietnam and a host of other nations might still today be amalgamated under the so-called Greater East Asia Co-Prosperity Sphere.
The Japanese Imperial Army was certainly guilty of uncountable atrocities, including genocide, the systematic rape of cities, and the starvation and abuse of prisoners of war. But at least it can be said that when they struck their most infamous blow against America, they went up against battleships and aircraft carriers, not office towers full of accountants and hedge fund managers.
