What was one problem that undermined the league of nations' effectiveness? a. it had no permanent army. b. it had very limited funds. c. it had few clear goals. d. it had no powerful leader. (only answer if you know)

 D. It had no powerful leader.

Explanation:

The United States never joined the League of Nations, in spite of the fact that an organization such as the League of Nations was the signature idea of US President Woodrow Wilson.  He had laid out 14 Points for establishing and maintaining world peace following the Great War (World War I).  Point #14 was the establishment of an international peacekeeping association. The Treaty of Versailles adopted that idea, but back home in the United States, there was not support for involving America in any association that could diminish US sovereignty over its own affairs or involve the US again in wars beyond those pertinent to the United States' own national security.   The lack of involvement by the world's fastest-growing superpower, the United States, hampered the League of Nation's effectiveness.
