The main reason that the League of Nations failed, was that the countries only thought for themselves.The absence of the U.S. was a large factor in the failure of the League of Nations, but the root cause of the failure of the League was that it had no real power.

After the War, in 1946, a formal organization called The United Nations was created, but it was not a continuation of the old League of Nations, which had been discredited by its inability to respond to the increasing belligerency of Germany and Italy.
