Japan's defence revolution and Australia-Japan-US trilateralism under Trump 2.0

A panel of experts unpacked Japan’s National Security Strategy and explored the opportunities and challenges for Australia-Japan-US trilateral strategic cooperation under Trump 2.0. The panel featured two prominent strategic thinkers from the US and Japan.Few countries have done more to reorganise themselves for a new era of strategic competition in the Indo-Pacific than Japan. Building on the strategic vision of former Prime Minister Shinzo Abe, Japan’s 2022 National Security Strategy, National Defense Strategy, and Defense Build-Up Plan provided a new framework for Japan to assume a more active and assertive role in regional security affairs. Since then, successive Japanese leaders have introduced new pieces of legislation, strengthened key national security institutions, increased national defence spending, and expanded Japan’s defence partnerships with the United States and Australia, including trilaterally, to address an increasingly volatile regional and global security environment.The logic of such cooperation remains sound even with the second coming of Donald Trump. Yet even trusted US allies like Japan and Australia are facing difficulties and uncertainty in their relationships with Washington. The threat of tariffs, demands for increased defence spending, reviews of marquee initiatives like AUKUS, and the dismantling of key US national security and diplomatic agencies all pose challenges to Australia, Japan and trilateral cooperation.How have Japan’s security policies developed in recent years? What more must be done to fully implement those changes? How are Australia and Japan navigating their relationships with Trump 2.0? Where is the trilateral defence partnership headed?To discuss these questions, USSC hosted a panel discussion featuring Yuki Tatsumi, Senior Director at the Institute for Indo-Pacific Security; Hirohito Ogi, Senior Research Fellow with the Institute of Geoeconomics at the International House of Japan, and Tom Corben, Research Fellow in the Foreign Policy and Defence Program at the USSC, moderated by USSC Professor and CEO Dr Michael Green.This event was part of the United States Studies Centre’s Assessing Implementation of Abe’s National Security Strategy supported by the Smith Richardson Foundation.
