If we're talking about an Axis victory, sure. If we're talking about a slower Allied victory, not so much. Yes, the Allies could respond, and their advantages in manpower and resources will eventually become telling. There essentially isn't a non-ASB victory for the Axis in anything resembling OTL WWII. However, there's no reason that the Allies' response wouldn't have to be something resulting in a delay, even if only by a few months relative to OTL. [SNIP]

Good enough for them. We'll do it, too.
Little things have dramatic effects. Who knows how many meathead decisions the drugged out whack-jobs on both sides made? But the other point is that things tend to smooth out to a mean. When the USN can predict to the week and to the casualties in kilodeaths, both men and machines in 1930 how long it will take to do Japan in via bombardment and blockade and do it without knowing what the 1945 tech is, then I suggest that means someone had a grasp on predictive outcomes.
