Australia can no longer assume the United States will guarantee its security or uphold the international order, according to The Australian National University (ANU) Emeritus Professor Hugh White in his new book, Hard New World: Australia's Post-American Future.
An expanded edition of Professor White’s bestselling Quarterly Essay of the same title, the book was published by Black Inc. on 24 August 2026.
Professor White, of the Coral Bell School's Strategic and Defence Studies Centre recently discussed the book in a Meet the Author event at ANU with Federal MP Allegra Spender in a wide-ranging conversation on Australia's place in a shifting global order.
Watch the full conversation here.
In Hard New World, Professor White argues that Australia can no longer rely on the assumption that America will guarantee its security or uphold a rules-based international order. He points to Australia's long-standing position as one of America's most geographically and strategically marginal allies, and argues that a fear of abandonment has shaped Australian foreign policy since before Federation.
That fear, he writes, was easy to set aside while America was strong and Asian powers were comparatively weak. With China's influence growing and America's regional commitment increasingly uncertain under Donald Trump, Professor White contends that Australia's leaders can no longer avoid the question of what comes next.
Professor White draws a comparison with Canadian Prime Minister Mark Carney's January 2026 address to the World Economic Forum in Davos, where Carney described the rules-based order as a "pleasant fiction" and warned against nations that continue to comply with it in the hope that compliance will buy safety. Professor White notes that Canada, unlike Australia, can never truly fear abandonment by the United States, given its direct border and the inseparability of Canadian and American security. Australia, he argues, holds no such guarantee.
