OOC- Just curious, how are the OTL Asian Tigers and China doing ITTL? Perhaps how they turn out would influence your DBWI.
Well for starters, if the Japanese hadn't reformed the Greater East Asian Co-Prosperity Sphere into being a true Co-Prosperity Sphere instead of a means to extract resources to feed their own economy than all of these countries would be much worse off.
It is a bit ironic how those countries managed to overtake Japan due to the 1990s Japanese Depression, and the ensuing political instability from there. In fact, the headquarters of the sphere is set to move from Tokyo to Phnom Penh in 2020.
