Answer:
The answer is A World War II
Explanation:
All though USA was a key player in forming the league of nations, USA never joined it. Moreover, the organization lacked influence, financial and political strength and leadership to counter many aggressive actions taken by European nations at the time.
The failure of setting up the League of Nations was one of the major contributors towards the rise and the expansion of Fascism in Europe and laid the foundation to ignite another World War.
