Which international organization was founded in 1945 to promote peace and cooperation among countries?

The United Nations was established in 1945 following the devastation of World War II, with the primary aim of fostering international peace and cooperation between countries. This organization serves as a platform for dialogue among nations, allows for conflict resolution, and aims to promote human rights, social progress, and economic development globally. The founding members sought to create a structure that would help prevent future conflicts and provide a framework for international law, humanitarian assistance, and addressing global challenges.

In contrast, NATO was formed in 1949 primarily for mutual defense against aggression, the WTO focuses on international trade, and the WHO is dedicated to worldwide public health. Each of these organizations plays pivotal roles in their respective areas, but only the United Nations encompasses the broader goal of promoting peace and cooperation among all member nations.
