Answer :
The aspect of the United Nations that made it a more effective organization than its predecessor, The League of Nations, was that the United Nations extended membership to all nations, even those that had been Axis Powers.
1. The United Nations had a broader membership base compared to the League of Nations. By including countries that had been part of the Axis Powers in World War II, the United Nations aimed to create a more inclusive and representative international organization.
2. This broader membership allowed for a more diverse range of perspectives and interests to be considered within the United Nations. It helped in promoting greater cooperation and understanding among nations with different historical backgrounds and ideologies.
3. In contrast, the League of Nations had limitations in membership and effectiveness due to the absence of major powers like the United States, Germany, and the Soviet Union. This restricted its ability to enforce decisions and maintain peace effectively.
4. By extending membership to all nations, the United Nations aimed to foster a more collaborative approach to international relations and promote collective security, making it a more robust and influential organization than its predecessor.
In summary, the inclusivity of membership in the United Nations, even to former Axis Powers, played a key role in making it a more effective organization compared to the League of Nations.
