Which term refers to a composed collection of governments that cooperate on common issues?

The term that refers to a composed collection of governments that cooperate on common issues is Intergovernmental Organizations (IGOs). IGOs are established by treaties between sovereign states and are designed to address specific global or regional challenges, such as security, trade, health, and environmental concerns. The cooperation among member states in IGOs allows for collective action and policy coordination, thereby enabling countries to tackle issues that transcend national borders.

For instance, organizations like the United Nations (UN) and the North Atlantic Treaty Organization (NATO) exemplify how countries can come together to address security, humanitarian, and economic issues effectively. The focus on collective decision-making and shared objectives distinguishes IGOs from other entities, demonstrating their vital role in international relations.
