What are the shortcomings of the Paris Peace Conference that ended World War 1?

The Paris Peace Conference generated the Treaty of Versailles; in this conference originally 27 countries were deliberating, although by the end of the conference only 3 countries participated (United States of America, France and England). They generated the Treaty of Versailles, which included article 231, also known as the War Guilt Clause. This clause blamed Germany for the war, forcing Germany to take responsibilities and make reparations, among other ways, in the form of money to the allied nations. This clause and it's stipulations eventually led to WWII as it led to the angst of the German people. This sentiments were satisfied only when Adolf Hitler began his regime.

In short, the downfall in the Paris Peace Conference was that it sentiments that led directly to WWII.
