You do realize that the west coast of the US would belong to Japan and there would be billions dead if they had won.
Please look up Unit 731 for an idea of how they would have died.
Even the Nazis were horrified by the excesses of the Imperial Japanese.
I’m horrified by the Leftists in America, who will EASILY give Imperial Japan a run for the money, should they (the Leftists) gain power here. They simply WANT US DEAD. Even Imperial Japan wasn’t that bad.
