What is a key function of NATO?

A key function of NATO, or the North Atlantic Treaty Organization, is to provide collective defense and security among its member countries, particularly in the context of military threats. Fighting terrorism is indeed one of the important aspects of NATO's role in current international relations. Following the 9/11 attacks in the United States, NATO invoked Article 5 of the North Atlantic Treaty, which states that an armed attack against one member is considered an attack against all members. This marked a significant shift, as the organization expanded its mission to include counterterrorism efforts, enhancing security cooperation among its members.

While NATO does engage in various other activities such as crisis management and disaster relief, its overarching aim remains focused on collective defense and security. This emphasis on military cooperation and addressing threats, including terrorism, is vital in a world where security challenges are increasingly complex.
