See here’s the deal: Germany could WASTE Russia in short order if there were no other players, right? But he/she can’t because the western Allies require Germany to spend some of her IPC’s to counter their threat, right? So USSR is free to spend a whole bunch of IPC’s just fighting Germany with Allied help, right?
That’s where YOU come in! It’s not japan’s task to “kill” USSR (though that is sometimes possible) only force USSR to SPLIT her meager funds to fight both you AND Germany! Meanwhile you can pound on UK and USA (the Western Allies) to pick at their assaults on Germany.
So…gain control of the Pacific. Don’t lose capital ships. Use a minimum of money holding off the Western Allies. Build (or capture) an Industrial Complex in Asia and put 3 ARM, 4 INF onto the Continent each turn. If you can keep this up, and move reasonably aggressively, you and Germany can win the game. Simple as that.
This is not the be-all, end-all of Axis strategy, only the beginning…
