Okay good point about the threat WWII Japan posed but you’re going too far in the other direction. When asked about going to war with America admiral Yamamoto said what amounts to “this is a bad idea don’t”. Now part of their failure definitely lies in poor leadership, and I can see the idea that if they’d concentrated on America instead of opening a war on three (two and a half?) fronts they might’ve made significant gains until America’s industry caught up, but they simply didn’t have the industrial base to keep the US down. The US also has very good natural defenses that you forgot to take into account. Remember: Their ships and airplanes were all handmade.
