OK in the Lore we have references to Battles that IRL where Pacific Theatre WWII, but we have no info on who the Union and the Allies are fighting against?

The Battles mentioned only make scene if your trying to keep some one out of (or trying to get in to) Indo-China, China and the Jappinise Home Islands, problem is Siam was an Allied Nation in WWI Vetnam & Cambodia where French Colonials, Burma & Singapore where British and what is to day Indonesia & Timor where Dutch. France & Englend are Allied powers in both RW WWI and in the U-Cononic and IRL at the time the Dutch where Nuteral. Futher North China & Japan where part of the Allied Nations IRL, so unless their is a U-Cononic reason for them to be otherwise it must mean that one of the major (Non Allied) powers has Subverted or Concurred one or more of those regions.

So Who are the Allied Powers fighting against in the Pacific Thearter?

Hmm it would make for a 'very' cool add-on to have an anachronistic Imperial Japan.

At the moment the battle is centered on the european/mediteranean front. We have no clue on what's happening elsewhere on the globe...
