What is an example of a military alliance?

NATO, the North Atlantic Treaty Organization, serves as a prominent example of a military alliance. Established in 1949, NATO was formed primarily for collective defense against potential aggression, particularly in the context of the Cold War. Member countries agree that an armed attack against one member is considered an attack against all, thereby promoting mutual defense among its allies. This principle is crucial for maintaining peace and security in the North Atlantic region.

In contrast, the other organizations mentioned focus on different areas of cooperation. The European Union is primarily an economic and political union that fosters economic collaboration and integration among its member states but does not operate as a military alliance. The World Trade Organization is dedicated to regulating international trade and ensuring that trade flows as smoothly and predictably as possible but does not involve military commitments. The Commonwealth of Nations, while it involves political and cultural cooperation, does not function as a military alliance like NATO does.
