@Bob77:
Hmm. That brings up an interesting question.
If some how japan attacked russia on the euro map while russia still neutral in europe, would russia still be neutral there?
Or could american bombers land in pac russia if japan and russia are neutral, but italy and germany have taken russian territories on pac map?
Wont happen, but wondering.
This is, I believe, directly answered in the rules. E40 p. 37:
Due to its separate treaties with Germany and Japan, the Soviet Union is in a unique position in its relationship with the Axis powers. As a result, if the Soviet Union is at war with Axis powers on only one map, it is still under the restrictions of being a neutral power (see “Powers Not at War with One Another,” page 15) on the other map, and Axis powers on the other map are also still under those restrictions regarding the Soviet Union on both maps. For example, a state of war with only Japan lifts the neutrality restrictions from the Soviet Union on the Pacific map only, and allows Japanese units to attack or fly over Soviet-controlled territories on either map. However, the Soviet Union is still restricted on the Europe map, and Germany and Italy must still treat the entire Soviet Union as a neutral power, and may not move units into or through any original Soviet territories or Soviet-controlled territories. At the same time, Allied powers may move units into or through Pacific original Soviet territories and Soviet-controlled territories, but not European ones.
If somehow Japan attacked Russia on the European map while Russia is still neutral in Europe, would Russia still be neutral there?
Yes.
The harder question is, could Russia then attack these Japanese-held territories?
As written, the rules seem to say no. But I might be sympathetic to a player who argued that Russia should be able to attack Japanese-held formerly-Russian territories on the European map–assuming no Italian or German units are in them at the time. Except of course that, by this time in the game, Russia probably has the ability to DoW whomever it wants: if that’s the case, I’d live by the letter of the rules.
Could American bombers land in Pacific Russia if Japan and Russia are neutral, but Italy and Germany have taken Russian territories on the Pacific map?
No.
