叫嚣要买下美国is a big mistake. China do but don't say.

It become interdependent with USA first which Japan didn't do. Also combinational efforts with Europe helped USA back then, but China did well in Europe economically as well and successful in splitting parts of EU away from one another. Japan didn't. On Timing, EU is vying EUD against USD as an International currency replacement option. China's Yuan went into the race and play them off each other. Japan then didn't have such timing and EU and US still buddies. Other than these, military occupation by US did wonders to force Japan to sign.
