Question

Why were president Wilton's fourteen points not incorporated in the treaty or Versailles

Answer 1

http://en.wikipedia.org/wiki/Fourteen_Points

Many countries were skeptical of his idealism too.

Answer 2

"Wilson subsequently used the Fourteen Points as the basis for negotiating the Treaty of Versailles that ended the war. Although the Treaty did not fully realize Wilson’s unselfish vision, the Fourteen Points still stand as the most powerful expression of the idealist strain in United States diplomacy."
