The suggested Persian strategy really makes me hope that the Allies are not permitted to invade neutrals.
The British could then simply march Commonwealth units straight through Persia into Sevastopol and essentially that’s the UK joining Russia on the Eastern Front.
If the Allies are allowed to invade neutrals, and the UK can place more than the odd piece in India, then we’re heading towards a game that is little more than a production race with no real room for strategy.
At least if the giant “Sevastopol” tt were divided east/west then the Turks might stand a chance of heading them off in the Caucasus; I suspect this may become a common map amendment.
