Final answer:
France's strategy for war with the Nazis focused on building elaborate defenses that were easily overcome, such as the Maginot Line.
Step-by-step explanation:
The strategy France adopted for war with the Nazis focused mainly on building elaborate defenses that were easily overcome. One of the key aspects of this strategy was the construction of the Maginot Line, a system of fortifications along the French-German border. However, the Germans bypassed these defenses by attacking through Belgium and Luxembourg, catching the French off guard. As a result, France was quickly overwhelmed by the German invasion in 1940.
