Sorry if these questions were asked before but:

You started off with the Showa period being the upswing of Japanese imperialism? But WWII isn't actually that far from the actual main series? Less than two years probably. So did, in this timeline, the Japanese win WWII? Like, was Tokyo never firebombed? Did we not get the two nukes? Or maybe the nukes didn't have as big an impact? Or maybe the Japanese didn't win the war but the Americans didn't have as heavy a hand in writing the Japanese constitution? Like, what's up with that?
