What is the primary function of the United Nations?

The primary function of the United Nations is to promote international cooperation and maintain peace and security. The UN was established in 1945, primarily in response to the devastation caused by World War II, with the core mission of preventing future conflicts through dialogue, diplomacy, and cooperation among nations.

The UN serves as a platform where member states can come together to discuss and resolve international issues, ranging from security threats to humanitarian crises. Its various bodies, like the Security Council, work to address violations of peace and security, while other agencies focus on development, human rights, and environmental concerns. This cooperative approach is essential for fostering a stable international order.

The other choices indicate functions that, while important in their own right, do not encapsulate the overarching mission of the UN. For instance, enforcing military actions against rogue states is certainly a possibility under specific circumstances, but it does not define the UN's primary purpose, which relies heavily on diplomacy and collaboration rather than military intervention. Similarly, regulating global trade and commerce and providing humanitarian assistance, while crucial areas of global concern, are more specific activities rather than the foundational mission of the organization.
