I have not studied the Sino-Japanese war in depth but I think if Japan had wanted to win that war bad enough, it had the manpower and resources to do so. They could have mobilized 20 or more additional divisions (as I do) and used them there but the cost would have been incredible. That war was an extreme version of 'mission creep' and I agree that war vs. the Allies probably wouldn't have happened without the stalemate in China. And by winning I mean discrediting the Nationals government and either puppeting or conquering the most populated areas. But with the USSR on the northern border, much of their army is not available to 'finish' the job. I have seen Japan stopped in China for years, it does occur but probably less than 50% in SF and I imagine similarly in FTM. I've not seen the world's 3rd largest navy used for amphibious or carrier missions as was done historically against China. Again it is a matter of balancing the game for both MP, solo and AI, hard to do. I notice that VP's are now located mostly in the interior, as are the starting National armies, so that's an improvement.
