What is NATO known for?

NATO, or the North Atlantic Treaty Organization, is primarily known as an international military defense organization established in 1949. Its main purpose is to ensure collective defense and security for its member countries, primarily in North America and Europe. Member states agree that an armed attack against one shall be considered an attack against all, which is outlined in Article 5 of the NATO treaty.

This military alliance focuses on protecting its members from external threats and fostering cooperation in defense-related matters. While NATO may engage in humanitarian efforts and support peacekeeping missions, its core identity and operations center around military defense and collaboration in security strategy.

In contrast, humanitarian aid is typically provided by organizations specifically focused on relief efforts, while promoting economic partnerships and regulating international trade fall within the purview of other entities like the World Trade Organization (WTO) or regional trade agreements. Hence, the distinct focus of NATO on collective military defense makes it the correct answer in this context.
