I agree on the Maginot line. The Germans attacked through that area in 1870, so the French always thought they would attack there again. They didn't in ww1 so the French where stupid to think that they would do it again. And besides, if you had two choices;
-attack through a heavily defended area, all according to the enemy's plan
OR
-walk through a neutral country to attack they lightly defended bit.
If the French had extended the Maginot line on ALL of France's borders, the war might of been different. The would have to fortify the beaches as well in case Germany wanted to do an amphibious landing.

Of course, the French could of not built it and made their army bigger and better.
