“Too many Americans assume that every conflict must have a good side and a bad side. Not true. More often than not both sides are bad. That was certainly the case both in WW1 and with Chiang Kai-shek versus Japan. Adults realize that some situations are unfixable. You just have to wait them out because any effort to intervene just makes matters worse. Sadly… The closer you look, the worse the case against the U.S. war with Japan becomes. If you’re going to pick a fight with someone, as FDR did with Japan, and then sacrifice vast wealth and innocent young lives to that purpose, you had better make damned sure you leave things better than you found them. But the exact opposite happened in the case of the Pacific War.”
