Australia, New Zealand, United States Security Treaty (ANZUS)

The Australia, New Zealand, United States Security Treaty (ANZUS) is a formal agreement formed in 1951 that commits Australia, New Zealand, and the U.S. to cooperate on defense and security issues. It emphasizes mutual support if any of the member countries face attack or security threats in the Pacific region. While the treaty mainly facilitates intelligence sharing and military cooperation, it also ensures the allies work together to promote regional stability and respond collectively to threats. Over time, some aspects have evolved, but the core aim remains to strengthen security ties among these nations in the Indo-Pacific area.
