ANZUS

The Australia, New Zealand, United States Security Treaty is a collective security agreement between Australia, New Zealand, and the United States that was signed in 1951, and from which New Zealand has been partially suspended since 1986.

The following provisions require the parties to maintain their "capacity to resist armed attack", consult with each other on security matters in the Pacific and declare that an armed attack on any of the parties "would be dangerous to [each signatory's] peace and safety" and that each signatory "would act to meet the common danger in accordance with its constitutional processes". It also provides for a council of the signatories foreign ministers, in which the implementation of the treaty can be discussed.
