I wonder what would have happened if the allies had screwed Belgium over and not advanced to protect it.
As well as the crazy political situation in France, their army was also far too top heavy and old, and relied on ww1 era comms. I saw the average age of the high command was something like 30 years older in France than Germany.
Maybe you could say the top heaviness was due to French politics, and that the the old generals did not invest in new comms, but I think that is a stretch.
But, yes, I agree with you. The maginot line did exactly what it was supposed to do
No
The Maginot Line forced the german army to go through the ardennes. It bunched up all their forces into a tiny crossing surrounded by valleys rivers and other such obstacle.
Two french spotter planes saw this and reported back. The report was regarded as spurious.
Had the report been acted on, the invasion of france probably would have failed.
France and britian had by far the best kit and numbers. However the french were in disarray politically, and the british weren't really integrating properly.
So the real reason barrier was the lack of joined up political thinking.
