Answer:
President Wilson believed that on the basis of his 14 points it would be possible to overcome problems and animosity created during WW1. But, his peaceful solution of problems wasn't accepted by many countries, especially those who won the war. Britain, France and many others believed that Germany and its allies should be heavily punished. Therefore, most of Wilson's ideas were not accepted, and the peace treaty that was signed let to further conflicts and problems.
Step-by-step explanation:
Wilson's idea was not even totally accepted in US. United States decided not to participate in the League of Nations, organization that was created after Wilson proposed its creation.
On the other side, Versailles Peace Treaty eventually led to rise of Totalitarism in Europe.
Wilson's ideas were not accepted and new conflicts were in front of everyone.
