DEI is not neutral. If it was a pro-allies neutral it would look like Eastern Persia. There’s special rules for Mongolia but it is neutral, not Allied.
DEI has its own roundel because Netherlands is Allied. If they wanted it to be a neutral, they would have the vertical/diagonal lines running thru the DEI and say “-neutral”.
Is French Indo-China a pro-Allies “neutral”? By your logic, it must be. But it just isn’t.
Yes, Japan is only at war with China. Inevitably, Japan will be at war with US UK ANZAC. So while neutrality exists, the two factions also exist from the beginning and inevitably clash.
All I’m saying is that it is fine if you want to disagree with the rules and play how you want. I’m just asking that you and others don’t obstinately spread misinformation when faced with the actual rules.
