That’s just it, though. You can reclaim W. USA if you like to think of it that way, but then you have to counter 10 ground units a round from Japan. (Because I will eventually have a train of 5 transports because I can produce 10 units in Japan a round.)
However, thats at minimum 30 IPC and more realistically 45-55 IPC a round out of your 60 IPC income (fine, 65 IPC, maybe.)
Or you plan to hold it, taking at least 25 IPC a round for 3 or 4 rounds (about how long it would take Japan to set up a decent transport train to attack it and trade with America. However, this is cheaper because it is spread over the first few rounds and more efficient since Japan won’t bother attacking against a well staged America.) The drawback? You do not have the equipment to save London and England will fall. Meanwhile Italy is gobbling up Africa since England cannot invest to stop them and Japan is sending annoyances down to ANZAC/UK Pacific to prevent them from growing. (They’re weak as shit, just keep them weak as shit.) From there it’s really only a matter of keeping China at 3 or 4 territories (simple enough) and staging in Yunnan. You dont have to take Calcutta, England will cower there to stop you. However, just having a large force near will stop him from expanding.
Then Germany with all of Europe and an infantry in Egypt for the NO should have more than enough power to crush Russia and win with NOs. (Moscow, Leningrad, Stalingrad, Berlin, Rome, France, Cairo, London).
What I am getting at is that if the Axis powers move quickly and efficiently there is nothing the Allies can do to stop them from winning the game. This is very similar to AARe in which the allies had to play extremely carefully to stop the Axis from winning before the allies grew to sufficient power. The main difference here is that you can stop teh allies from collecting more than you if you move appropriately.
