Why is the French army, known as the strongest army in World War II, so rubbish?

1. The backwardness of tactics and the brand-new blitzkrieg and "three-dimensional war" brought by the Germans made the French very shocked and at a loss.

Generally speaking, France is mainly defensive, so soldiers are not aggressive. The policy of appeasement is pacifism and even fear of war (the reason why World War I was too cruel).

3. The headquarters is gone. In modern warfare, it is very important to have a command/headquarters/general staff department that takes care of the overall situation (think of the now touted "decapitation" action) and see who was in command at that time-Barton, this guy surrendered!

4. morale. This thing is invisible and intangible, but it is very important! A few days after the start of the war, news of defeat came from all the battlefields, which was terrible. When words spread from one mouth to ten, everyone lost morale and confidence in the end. How can we fight?

PS: Finally, I really don't like the titles of "XX military power" and "X military power", which were originally used to deter enemy countries, but in the end, if I believe too much, I will be harmed by them! Therefore, as a native of China, I am very wary of being labeled as a "X country" by the west. Remember to be prepared for danger in times of peace!
