Why should the US join the League of Nations according to Wilson's idea?

The U.S.A. did not join the L.O.N. after Wilson's presidency ended because they adopted a policy of isolationism and did not want to get caught up in European affairs due to them being so far away. The American Government wanted to take a greater interest in Aisa because it was much close r to home.

The question of the League of Nations was taken up in Senate. Because of the conservative rule in the Senate, the Senate turned down joing the League of Nations.
