Why wasn't the Treaty of Versailles effective?

The Treaty of Versailles was created almost vindictively by the West since they were seeking justice from Germany. This caused major social and economic problems in Germany as they were not only forced to take blame and return territories, but also pay large reparations to Britain and France. These harsh terms inevitably led to World War II, as bitter and resentful German citizens were easily swayed by Hitler's promises of revenge. The Allies attempt to restrict Germany’s power also failed, as they used a strategy of appeasement when Hitler tried to expand, rendering the rules of the treaty useless.
