Final answer:
The United Nations (UN) is the organization where nations discuss global issues; it has elements of both confederation and federal systems in its power structure.
Step-by-step explanation:
The organization referred to in the question is the United Nations (UN), which is a central hub for international diplomacy and a platform where its 193 member states can voice concerns, discuss global issues, and work together on solutions. The UN has several main bodies, including the General Assembly and the Security Council, that facilitate collaboration among nations. The power distribution within the UN is complex, but it combines aspects of both a confederation (since member states remain sovereign and have equal representation in the General Assembly) and a federal system (since decisions of the Security Council are binding on all members).
