Thanks for the answer. This is an interesting NO as it doesn’t rely totally on Japan’s actions. Most of the NOs generally rely on that particular country’s actions (capturing and/or controlling certain territories, Italy clearing the Med of Allied warships, etc.) yet Japan could lose this NO through no action of it’s own. If Germany takes London and the US declares war on ALL Axis, then you could say that Germany cost Japan 10 IPCs per round. Although, technically, the US COULD just declare war on Germany and not on Japan, thereby Japan could still receive that NO for not being at war with the Western Allies. By the way, thanks for clearing up that Russia was not included in this NO. I guess that is because they have their own separate NO for the Non-Aggression Pact violation.
If India or ANZAC decide to attack Japanese forces or move units into China, that also voids the “Japan not at war” NO, right? Funny, I always thought this NO depended entirely on Japan NOT declaring war on anybody, as sort of a hedge against Japan’s expansionism. I didn’t realize that it could also be voided by any of the other powers attacking Japan.
