The primary goal of the United Nations when it was formed in 1945 was to promote international cooperation and maintain peace and security in the aftermath of World War II. The UN aimed to prevent future conflicts through dialogue and diplomacy rather than military confrontation. It sought to create a platform for member states to address global issues like human rights, development, and humanitarian assistance. Additionally, the UN established various specialized agencies to tackle specific challenges, fostering collaboration among nations. Overall, its foundational mission centered around fostering global peace and security to avoid the cataclysm of another world war.
