Explain why France was bitter towards Germany more than any other country?

France's bitterness towards Germany primarily stems from the Franco-Prussian War (1870-1871), which resulted in a humiliating defeat for France and the loss of Alsace-Lorraine. The subsequent establishment of the German Empire was seen as a direct threat to French national pride and security. Additionally, during World War I and World War II, Germany's invasions and the devastation wrought on French territory deepened this animosity. The legacy of these conflicts fostered a lasting resentment that influenced French-German relations for decades.
