We should learn from Japan's way of losing WW2 is importance of supplies for soldiers and of avoiding being optimistic about the extreme situation.
Lack of foods or forcing soldiers to tolerate with harsh situations made troops destructive situations. According to a statistics, most of the Japanese victims during WW2 were killed by starving or disease, not by being shot or bombered.
