Why was the Treaty of Versailles considered a failure in WW1?

The treaty of Versailles had created massive problems within the newly formed democratic Germany. Forming massive debt and loss of territory to a type of government that had not been used at all throughout German history. This led to massive political instability and hatred. As German situations worsened (for example the Great Depression) radical parties such as the Nazis had grown into power in the democracy. The NSDAP (Nazi Party) had promised the German people to fix the massive unemployment rate and poverty which became very popular and soon many nazi members were elected to sit in the Reichstag (Parliament.) After Hitler took total control over Germany, he had defied the treaty of Versailles terms by cutting off the payment of war debts and militarizing the Rhineland. He also expanded the military and created a new Navy and Airforce. This was considered an absolute blow to the Treaty of Versailles because the British and French had done nothing to stop Hitler's defiance against the treaty. This made the Treaty of Versailles completely pointless and helped a dictatorship rise in Germany.
