Our perspective of what should have been done versus what was done has to be informed by what was going on at the time. By the time of VJ Day, we could already see the outlines of the next war against aggressive Communism as sponsored by Stalin and the Soviet Union. In Europe there was the exhaustion of resources and the masses of 'displaced peoples' (DPs) that kind of locked the borders where the Armies stopped.
In Asia, within months, the last-minute entry of the Soviet Union was causing 'problems' in Korea & Manchuria while the Chinese Red Army moved almost immediately against their internal rivals of the Chinese Nationalists. The need for rapid 'pacification' of Japan became a priority while also modification of its society to destroy the Bushido / oligarchic culture within Japan.
History is always all kind of shades of gray and what comes in war's aftermath frequently has many of the darker shades. An example of horrible acts from Europe at this time was the forced repatriation to the Soviet Union of hundred of thousands of people who had no desire to go when they KNEW that they were looking at prison at best.
I agree.
Not that I agree with the actions, but the occurrences and why they occurred. I try hard not to judge people in the past by today’s standards.
