Historically, Japan was after our political will; they all knew there was no hope against our capability. Once our will was mobilized, Japan had no possibility of victory. Ultimately, we win. The game has no methodology by which to judge political will, nor should it.

"Ack! You're kicking my b---!!! I surrender!" [;)]
