will never happen because japs hate china and china hates japs, same with korea. there's a good reason that japan friendlied up to the western powers real quick after ww2, they had literally no allies on their own side of the world because a keystone of their military strategy was "kill the men and rape the women so the next generation doesn't know what to do with themselves." Although that's not to absolve china and korea of any of the numerous historical atrocities they committed.
