President Woodrow Wilson first mentioned the League of Nations in his Fourteen Points speech while discussing ways to limit more wars in Europe. Under one Article of the league, any nation under threat required all other nations to assists. This meant that otherwise peaceful nations were going to be required to assist. Because of this article, congress was too afraid to join the league as it feared it would give up American isolationism. Therefore, before the United States could join the League of Nations, it would have to change from an Isolationism mindset to a more interventionism ideology.
I hope this helps! :)
