I saw someone here post a strategy for Japan to help Germany: Japan conquers neutral Switzerland, puts an IC (factory) on it, then buys 3 infantry for it every turn.
That seemed clever, but I could not find anywhere in the rules that tells you what the production capacity of a neutral country is. I think the poster was assuming that because it costs 3 IPCs to violate neutrality, it must have 3 units of production capacity, which is mixing up two unrelated subjects.
For what it is worth, when you play the CD-ROM game, a factory on a formerly neutral country has only 1 unit of production capacity per round.
Does anyone have any hard documentation that it should be otherwise?
