Which international organization was established after World War II?

The United Nations was established in 1945, following the devastation of World War II, with the primary goal of promoting international cooperation and preventing future conflicts. This organization was created to foster peace and stability worldwide by providing a platform for dialogue among nations. It replaced the League of Nations, which had been unsuccessful in maintaining peace during the interwar period.

The UN was founded on the ideals of collective security and human rights, bringing together member states to work collaboratively on issues such as humanitarian aid, development, and the protection of human rights. Its establishment marked a significant shift in how countries interact on a global scale, emphasizing diplomacy and cooperation rather than conflict.

Other organizations listed, like the League of Nations, were established prior to World War II and did not succeed in preventing the war. The World Trade Organization and the International Monetary Fund were created later, in 1995 and 1944 respectively, focusing specifically on economic issues rather than the broader goals of peace and security that the UN addresses.
