To what extent was the Treaty of Versailles responsible for the outbreak of World War 1?

In case you are referring to what parts of the Treaty are
related to the causes of World War I.  The answer to that would be many of
them. 

Wilson's Fourteen Points, which were his framework
for world peace after World War I, included obvious causes of war such as battles for
control of the oceans and waterways, alliances in World War I which gave countries a
sense of overconfidence in victory, and more likely to start wars, and national
self-determination - minority populations living within imperial borders. He sought to
address all of these, and create a League of Nations in the Treaty of
Versailles.
