I think it has more to do with the decline of France. France was an elite power in the 18th and 19th century only to turn tail when it mattered most in the 20th century.That was not the first time the Germans had overpowered the French. It happened twice in the 70 years before WW2.
But the French are the ones hell bent on wanting to show the Germans their place. For example, the French were super eager to settle the score when they mobilized for WW1. Belgians and Dutch didn’t tr@$h talk the Germans, like the French do. The French are ridiculed for their arrogance.
