And if it must happen, id be more than happy to npc Japan!! If it happens, ill likely follow historic events so as to retain uniformity in the pacific. 

I'm sure someone will find it to be biased as I am using the united states as my primary but the offer is there!

Edit: It would actually be fun as I plan on making a few side characters (mainly soldiers)  the war on both Europe and pacific theaters, it'd be pretty fun to make some npc's for both sides.
