Japan, Italy, and Germany signed a war treaty in September 1940. Going to war with Japan essentially meant going to war with Germany.

>Sure, you had to go after them after that atrocity. But the obvious move of declaring war on Japan didn't mean you had to include Germany. Russia had no beef with Japan (Hitler had hoped that Japan would engage her eastern flank but that didn't happen). I don't think that WWII was one war: You had your Pacific struggle vs Japan, Russia fought her great Patriotic War vs the Germans and I don't think that Japan and Germany had that much truck with each other over the whole affair. It's not as if they had a grand plan between them.

>>>You're missing the point: I mean after Adolph had declared war on you. Yes, you could have just sat there as his declaration was essentially meaningless in that he didn't have the means to engage you unless you came to him - other than like the U-boat losses you'd already incurred before you joined the party.
