Happy nightmares.
I have read them.
My comments are not specifically related to the incident in Korea or Korea-Japan relations in general, or the brutality of the Japanese military dictatorship. They are about the general conditions in Asia in the period when Japan was just about the only Asian nation modernizing and getting into real industrialization, which was also a period when so much of Asia was colonies occupied by western empires. Japanese were not the only Asians wondering at the time if the future of Asia was to be forever run by westerners. While WWII ended the Japanese adventures in empire building, it also began to lead to the end of western colonies in Asia as well. Had the latter not been true, there could have been a revival of some combination of Asian states to end western colonialism in Asia.
