Why Btonze Age?

Also, the German style of armored warfare is not as invincible against the French style of warfare as one might
Think.  The main thing that allowed the Germans to achieve the swift victory was still the fact that the Germans found a pass around the French army where the French were confident there was an impenetrable natural barrier.  Had the Germans not found the pass, and then gambled everything, literally at the last moment, on using this pass, the attack against the Low Countries and France would likely ended up much like the operation citedel in Ukraine in 1943, with German panzers bashing their own heads in against strong layered defenses, failing to achieve any sort of break through on a scale that can overwhelm French reserves.

Interestingly enough, the French armed forces ran wargames in the Ardennes in 1938 which showed that a tank breakthrough through that area could be completed within three days, the actual German breakthrough took 57 hours.

Yeah, and prior to the battle of midway, the planning staff of the Japanese combined fleet wargamed the upcoming operation, and achieved a result almost exactly the same as how battle actually turned out.  But the operation went ahead without any change anyway, because the operational staff has never yet had one of their major operations fail.   The result was Japan lost 4 of her 6 fleet carriers, just like the pre-battle planning wargames said.

I guess even worse then not learning from the last war, and even worse than not anticipating the conditions of the next war, is to have done both but went ahead and done really stupid things anyway.
