ANZUS, AUKUS and the forthcoming change of administration in the United States in 2025.

Sir Angus Houston reviews the ongoing vital importance and current health of the 1951 Australia, New Zealand, United States Security Treaty (ANZUS) focusing on the defence and security partnership that has developed between Australia and the United States since its inception. He then examines promising progress being made under both Pillar 1 and Pillar 2 of the 2021 Australia, United Kingdom, United States Trilateral Security Partnership (AUKUS). He concludes by considering the likely foreign policy of Donald Trump, president-elect of the United States, who will assume office on 20 January 2025. [ABSTRACT FROM AUTHOR]
