EXPLANATIONS BELOW
Concept note-1: -After some notable successes and some early failures in the 1920s, the League ultimately proved incapable of preventing aggression by the Axis powers in the 1930s. The credibility of the organization was weakened by the fact that the United States never joined, and Japan, Italy, Germany and Spain quit.
Concept note-2: -The American Senate voted against America joining the League of Nations, despite it being Woodrow Wilson’s idea. Other important countries such as Germany and the USSR were not allowed to join when the League was formed.
Concept note-3: -Likewise, none of the European microstates of Andorra, Liechtenstein, Monaco, San Marino, and Vatican City ever sought membership in the organization.
Concept note-4: -Russia was expelled out of League of Nations for invading Finland and USA never joined the league, ironic because it was America who designed it and these were the two major countries who were not members of League of Nations. Was this answer helpful?
