How did France help cause WW2?

France's role in causing World War II can be attributed to its post-World War I policies and its approach to German aggression. The harsh terms of the Treaty of Versailles, which France supported, aimed to cripple Germany but ultimately fostered resentment and economic hardship, setting the stage for extremist ideologies to gain traction. Additionally, France's reliance on the Maginot Line for defense and its failure to effectively counter early German expansionism, notably during the remilitarization of the Rhineland and the annexation of Austria, weakened the collective security in Europe. These factors contributed to the broader instability that facilitated the outbreak of the war.
