On a side note I do feel Germany should be rewarded for Russian conquest by having Turkey and Spain ally with them since they were on the fence to begin with.
I believe that neutrals are likely to join the stronger power, and not the loosing one. Its opposite in A&A games because of balance. If you occupy a true neutral in this game, all the neutrals in the world will turn against you. This is a design to script the game to follow a historical correct path. Every WWII games have this flaw. But the real war was different. After Germany crushed neutral Poland, all the minor neutrals like Finland, Romania, Hungary, Bulgaria, Slovakia etc joined the strong Germany. Not one minor would go to war against the strong Germany at that time. But after Russia had proved to be stronger than Germany, all the former German allies mentioned above, switched side and went to war against Germany. Major neutrals like Sweden, Spain and Turkey made trade agreements with the strong Germany after Poland got crushed, but after Germany lost at Stalingrad they all switched side, and started to support the by now stronger Allies.
But how to implement realistic rules into A&A ? Maybe ditch the 5 IPC NOs Germany get after capturing Russian cities, and rather give them the IPC income from the true neutrals, representing trade agreements. And when the tide turn, let the Allies get the trade income from the neutrals. After all, the NO was designed to make a short game, so it doesn’t matter from where they take the IPC.
