>It failed because the Nazis used unprecedented tactics and technology to storm through Belgium and the Netherlands faster than anyone thought they could; The German war plans were captured by the Belgians in 1940's "Mechelen Incident". The Germans subsequently changed the plan, but the allies reacted to the German attack assuming the original plan. The final ("Manstein") plan was a big gamble on Germany's part, and the generals hated it because the German army would have be obliterated if the allies countered properly. Your basic point is correct, though. It's easy to blame France's collapse on the Maginot Line, but reality isn't so simple.
