This would make sense. All the historically neutral, aggressive, and defensive countries would predictably remain in the same state, for some male influence would remain even as the population trickled away. That and sheer cultural beliefs would pretty much ensure who would be the aggressors and so forth.

Japan changed a lot as a result of WW2. They were the aggressors at some point. They way I see it they could go either way as a result of this mess and the alternate history. It seems like it could be interesting if they come up with some sort of a cure first.
