re: OT - History Baws WW2 question

The French strategy post WWI was to play defense; consequently, they built the Maginot line.

But their neighbor Belgium didn't follow their lead thinking Germany would see a defensive line on their common border a threat. France realized that was a problem and when war broke out they sent troops into Belgium and along with the Brits planned to take a German offensive on there along the traditional German invasion route to France.

France had no offensive plans or capabilities so when war was declared, Germany had little worry about s French/British offensive and thus planned a vigorous invasion in the Ardennnes where opposition was weak and where their new blitzkrieg could be used to drive through the French positions and trap the Allied armies in France. They did not have to worry about the French troops in the Maginot line because they were all in defensive positions,

Tactically the French could have invaded Germany from Maginot positions, but the plan was entirely defensive and they had no way to take advantage of the situation.

The German panzers easily punched through North of the Maginot and their plan worked easily despite the risks they took,
