To me the rules are clear, and they prevent any cheese like triggering true neutrals into pro axis neutrals for the sake of claiming 3 IPCs per territory for Russia. However, the rules say nothing that prevents Russia from controlling Itallian Somoliland and claim 3 IPCs for the spread of communism. Therefore, denying this situation just because Italian Somoliland has zero territorial value would be a house rule IMO, and not a loophole in the rules that needs closing. Besides, this game is not in the position to take away advantages the Allies need desperately in order to compete.
