Frank. Let me be Frank with you. You do not know anything about what the Japanese did to all prisoners.
The Japanese did NOT pay the ultimate price in 1937. The United States had to bomb them twice before they understood. Your perception of history is quite distorted.
My study of history is accurate. They were utterly defeated, their country, economically and physically, completely destroyed, their militaristic government completely subdued, and their culture completely erased and changed. If you were in charge then what would have been the appropriate ‘ultimate’ price? The complete annihilation of Japan and the Japanese people?
