What major international organization was founded after World War II to promote world peace?

The United Nations was established after World War II in 1945 with the primary goal of promoting world peace and security. Its formation was influenced by the lessons learned from the failures of the League of Nations, which struggled to maintain peace in the interwar period. The United Nations serves as a forum for dialogue among nations, aimed at preventing conflicts and addressing global issues such as human rights, economic development, and humanitarian crises. This organization seeks to foster cooperative relations among its member states and is instrumental in various peacekeeping missions around the world.

In contrast, the League of Nations was created after World War I but was ultimately ineffective in preventing further conflicts. The World Trade Organization focuses on international trade and economic policies, while the International Red Cross is dedicated to humanitarian assistance and the protection of human life, especially in conflict situations, rather than overarching peacekeeping. Hence, the United Nations stands out as the major organization specifically aimed at maintaining global peace and stability post-World War II.
