I understand the sensitivity here, touching directly on questions of sovereignty and security. Trump’s America only exacerbates concerns about Australia being involved in a war with China. Yet the reality is that the Australian continent is more secure – and the prospects of conflict are lower – precisely because of Australia’s potential role in supporting the US military, not despite it. Canberra will need to do more to generate public and political support for this reality. Otherwise, defence establishments will lack the mandate to adequately prepare, and the government will struggle to generate the resources required.
A third inconvenient truth is the growing necessity for Australia to move toward collective defence with other Asian powers, notably Japan. Australian officials and experts rightly perceive the United States as a necessary but insufficient ingredient for regional security. Australia’s forthcoming strategy documents will likely emphasise the importance of middle power diplomacy, and Canberra has already demonstrated willingness to advance minilateral efforts in the absence of US leadership. Nevertheless, Australia’s actual commitment to building meaningful deterrence beyond the US bilateral alliance remains an open question.
The Australia-Japan relationship will be a critical bellwether of how far intra-ally alignment can get, with both sides reporting deepening cooperation across intelligence, policy and strategy. At the same time, it is not clear whether this activity will move beyond signalling resolve, or whether support for minilateralism in Canberra will translate into actual resources. Australia and Japan will need to ensure that defence cooperation produces real combat-credible deterrence, including the political authorities and integrated command structures required to fight together if necessary. Experts and officials may wince at the term “alliance”, but genuine deterrence (not just signalling resolve) will require Australia and Japan to move toward collective defence at an accelerated pace.
None of this is to dismiss what Australia has already put in motion – AUKUS, US force posture initiatives, the deepening ties with Japan and other partners all represent serious bets on the future. But the overall gap between requirements and execution is widening.
As someone who has helped manage the US-Australia alliance, I do not raise these questions lightly. More than one Australian interlocutor has warned that America might not like the answer it gets on questions of Australia’s defence budget, the US military presence on Australian soil, and the future of its defence ties with Japan. But these conversations are more necessary than ever. The current trajectory is unlikely to meet the scale of the task, and the costs of inaction will be severe if deterrence fails. As Joe Biden often said, “No foreign policy can be sustained without the informed consent of the American people.” The same will be true in Australia.
