This book explains why conflict between the US and China cannot be ruled out. In 1914 war between the Great Powers was considered unlikely, yet it happened, and the lessons we draw from its outbreak are usually mistaken. Among these errors is the tendency to over-estimate human rationality.

All major conflicts of the past 300 years have been about the norms and rules of the international system. In Xi Xinping’s China and Donald Trump’s US we find two powers whose values differ markedly, with China bidding to challenge the current order. The ‘Thucydidean Trap’ — when a conservative status quo power confronts a rising new one — may also play its part in precipitating hostilities. To avoid stumbling into an avoidable war both Beijing and Washington need a coherent strategy, which neither of them has.

The next global conflict may be played out in the new spheres of cyberspace and outer space, but like all previous wars it will have devastating consequences. Such a war between the United States and China looks less ‘improbable’ with every passing year.


‘Coker … always brings great historical, literary and philosophical erudition to his work … [A] thoughtful account.’ — Literary Review

‘Well structured, well argued . . . compelling.’ — European Review of International Studies

‘A stimulating book by one of this country’s least flashy public intellectuals and a timely antidote to the much-hyped “Thucydides Trap” thesis that rising and declining powers are destined to clash.’ — Michael Burleigh, History Today Books of the Year, 2017.

‘Christopher Coker has put forward a challenging argument: not that conflict between the US and China is inevitable, but that it is possible, and that both sides will have to sharpen their understanding of one another to avoid it. Coker draws richly on history, philosophy, and international relations theory to make his case. This is a highly stimulating account by a major thinker on one of the most important geopolitical questions of our time.’ — Rana Mitter, Professor of the History and Politics of Modern China at the Institute for Chinese Studies, Oxford University, and author of China’s War With Japan, 1937-1945

‘Provides an exceptionally clear and succinct discussion of what may well be the most important question of our age: does war between major states have a future, and, if so, what will it be like?’ — Martin van Creveld, author of The Culture of War and The Changing Face of War: Lessons of Combat from the Marne to Iraq

The Improbable War is a fresh, original book of great insight that advances a deeply troubling scenario. At issue is whether Beijing’s attempt to dictate the terms of US–China relations will so destabilise East Asia as to make conflict unavoidable. Christopher Coker asks if past is prologue.  We must believe that it is not. A brilliant book, and a great read.’ — Stefan Halper, Director of American Studies at the Department of Politics and International Studies, University of Cambridge and author of The Beijing Consensus: Legitimizing Authoritarianism in Our Time

‘Christopher Coker is one of a kind among scholars of international relations. In this sobering and stimulating book he opens a fascinating window on a looming confrontation, after which nothing will ever be the same again’. — Brendan Simms, Professor of the History of International Relations, University of Cambridge

‘Christopher Coker takes aim at what he considers a dangerous liberal misconception: that today’s world of complex, interlocked economies and shared interests has made war between major powers, such as China and the United States, irrational and therefore unlikely. … As Coker explains, ideology and emotional appeals to “national purpose” have just as much influence on states as sober cost–benefit assessments of the national interest. He stops short of predicting a Sino-American war, but he convincingly argues that the rise of China will be as disruptive to the U.S.-led international order as the rise of Germany after 1870 was to the British-led order of that era.’ — Foreign Affairs

‘This is a brilliant book that, despite its brevity, is far superior to its more alarmist counterparts that seem to get published far too frequently these days.’ — Survival
