What is the primary purpose of the United Nations?

The primary purpose of the United Nations is to promote international cooperation and maintain peace and security among nations. Established in the aftermath of World War II, the UN was created to provide a platform for dialogue and collaboration among countries to prevent future conflicts and foster diplomacy. Through its various agencies, such as the Security Council, the UN works to mediate disputes, facilitate negotiations, and support peacekeeping efforts.

The focus on cooperation reflects the understanding that global challenges, such as armed conflict, humanitarian crises, and development issues, require collaborative solutions. The United Nations aims to bring nations together to address these concerns through dialogue and joint action, making the promotion of peace and international cooperation central to its mission.

In the context of the other options, while regulating international trade agreements, deploying military forces, and dictating global economic policies may fall within the broader actions or responsibilities of certain UN bodies or related organizations, they are not the central, defining purpose of the UN. The organization's overarching aim has always been centered around maintaining global stability and fostering a cooperative international community.
