What was the primary goal of the United Nations when it was established in 1945?

The primary goal of the United Nations when it was established in 1945 was to promote peace and cooperation among nations. This objective arose in the aftermath of World War II, as the international community sought to prevent such devastating conflicts from occurring again. The UN was founded on the principles of collective security and diplomatic engagement, aiming to foster an environment where dialogue and collaboration could flourish. Through various means, including peacekeeping missions, mediating conflicts, and promoting human rights, the organization endeavors to maintain international peace and security.

Promoting economic development, while an important aspect of the UN’s work, is not its primary purpose. The creation of a global military alliance is more characteristic of organizations like NATO, which focuses on defense rather than peacebuilding. Enforcing international trade agreements falls under the purview of organizations like the World Trade Organization (WTO) and is also not aligned with the UN's foundational mission. Thus, the emphasis on peace and cooperation stands out as the central aim of the United Nations at its inception.
