Answer: Implementing his Fourteen Points proposal.
Step-by-step explanation:
The end of the First World War resulted in terrible consequences. The President of the United States was aware of the horrors that the war brought with it. To that end, he sent a fourteen-point amendment to the peace conference in Versailles. The amendment aimed to create a League of Nations for global peace. The League of Nations was formed, but Congress did not allow the United States to participate. For his engagement, Wilson was awarded the Nobel Peace Prize in 1920.
