Which organization's primary aim is international peacekeeping and cooperation?

The United Nations (UN) was established in 1945 with the primary aim of promoting international peace, security, and cooperation among countries. Its formation was a response to the devastation of World War II, with the goal of preventing such conflicts in the future through collective action and diplomacy. The UN engages in various activities that include conflict resolution, peacekeeping missions, and fostering global collaboration on issues like human rights, social progress, and humanitarian emergencies.

In contrast, the other organizations have different primary objectives. The World Trade Organization focuses on regulating international trade and ensuring that trade flows as smoothly and predictably as possible. The International Monetary Fund is primarily concerned with global monetary cooperation, providing financial stability and advising on economic policy. The North Atlantic Treaty Organization (NATO) is a military alliance focused on mutual defense and collective security among its members rather than broad international peacekeeping efforts.
