Well then house rule were minors can attack back without being at war with Russia only if being attacked by Allies.
IMO those 2 countries should be attacked right away so UK can’t attack from them.
You could also make it with no house rule and Ger,Itl are at fault for not taking them.
All are games have it where Ger takes Yugo, and Ger or Italy take Greece.
I do agree with ya on where the rule needs to be changed for Axis minors.
