This may have been asked before, but I'll be honest, I have no idea how you're supposed to win that thing. You're outnumbered to hell and back, Tokyo is heavily guarded, and your fleet is pitiful compared to the fascists you're fighting, preventing you from making a naval invasion. You cant break through with the forces you have either, and the fascists have forces on the other side to box you in. How the hell are you supposed to win this? For what it's worth, I have no idea why the AI takes this decision, because it can never win this stupid war.
