What term refers to a group of European countries formed to promote trade and reduce war potential?

The European Union is the term that refers to a group of European countries formed specifically to promote trade and reduce the potential for conflict among its member states. Established with the aim of fostering economic cooperation, the EU has progressively expanded its role to include promoting peace, stability, and prosperity across Europe.

One of the key principles behind the EU is that by creating economic interdependence through trade agreements and a single market, countries will be less likely to engage in conflicts. This has been a crucial factor in the post-World War II era in Europe, as countries that are economically linked tend to prioritize diplomatic solutions over military ones.

The other options represent different organizations with different primary focuses. The United Nations primarily aims to promote international peace and security on a global scale, the World Trade Organization focuses on regulating international trade between nations, and NATO (North Atlantic Treaty Organization) is a military alliance aimed at collective defense. While these organizations contribute to international relations and stability, they do not specifically exist to enhance trade and reduce war potential in the same manner as the European Union does.
