I only have 4 blocks, and I’m not sure how they can get trimmed to 5 without effecting the balance of risk vs. reward. I like your idea of treating Mongolia as 1 territory, but how does that work?
Because Mongolia is one country, you can’t make part of it pro japan, and another part pro Russia. That makes no sense. Second, part of the reason why i feel Mongolia should be off limits, is Japan tampering with it has no reality, as Mongolia was a quasi-soviet state. Third, If Japan is successful at swinging Mongolia, it voids the great rules regarding the non-aggression pact. Mongolia should be a special case, along with perhaps Switzerland ( they would never go pro axis), but just allowing Mongolia a special case is fine too.
The 5 groups should look like this IMO. Turkey has less concern for Europe, and more for Middle East.
