What is the purpose of the United Nations?

The primary purpose of the United Nations is to resolve world problems, which encompasses a wide range of issues including peace and security, development, human rights, and humanitarian assistance. The UN works to facilitate cooperation among countries to address global challenges, ranging from conflicts and humanitarian crises to climate change and sustainable development. By providing a platform for dialogue and negotiation, the UN aims to prevent conflicts and foster relationships that lead to peaceful resolutions, thus benefiting the international community as a whole.

The other options do not encapsulate the comprehensive mission of the UN. While the UN has various functions, such as promoting trade through its agencies and supporting international law, its central role focuses more on resolving disputes and addressing broader global challenges that affect nations collectively. It also does not govern the world in a traditional sense, as it operates on principles of sovereignty and relies on the cooperation of its member states to enact change.
