Is it difficult for Germany to win France?
The first thing:1September 1939, Germany attacked Poland, and then France declared war on Germany, but the French army held its ground on the western front. If the French choose to attack, "then they will undoubtedly break through the defense line" (confession of a Nazi general). Yes, France will beat Germany.

The second thing: When France was confidently guarding the solid maginot line,1May, 940, the German army adopted an extremely wise manstein plan, pretending to attack the Netherlands and Belgium, attracting the main forces of the French and British troops to the north (they went to defend), and then the German army used about five divisions of tank troops to insert into France from the Ardenmaran River, defeating the French Ninth Army with 300,000 people (the time when the French army collapsed was called At that time, France was still very strong, and the so-called most powerful army in the world was not bragging. This shows that there are still two brushes. It's a pity that France's high-level combat thoughts are seriously backward, and Charles de Gaulle's thoughts are completely ignored by them. I think the reason why France lost so quickly in World War II was not because its military strength was too weak, but because its thinking was backward.
