I'm not a fan of Stalin either but in this game the most brutal wins. The reason we beat the Japanese in WW2 is because we had the means to kill every Japanese in Japan with minimal losses to ourselves and demonstrated to them our willingness to do just that. That's what it will take to win the war on terror. Nothing less.
And we changed the Japanese religion. Won't likely to get Allah to make that radio address that saved the Japanese, though.
