It has become conventional wisdom that America and China are running a “superpower marathon” that may last a century. Yet Hal Brands and Michael Beckley pose a counterintuitive question: What if the sharpest phase of that competition is more like a decade-long sprint? The Sino-American contest is driven by clashing geopolitical interests and a stark ideological dispute over whether authoritarianism or democracy will dominate the 21st century. But both history and China’s current trajectory suggest that this rivalry will reach its moment of maximum danger in the 2020s. China is at a perilous moment: strong enough to violently challenge the existing order, yet losing confidence that time is on its side. Numerous examples from antiquity to the present show that rising powers become most aggressive when their fortunes fade, their difficulties multiply, and they realise they must achieve their ambitions now or miss the chance to do so forever. China has already started down this path. Witness its aggression toward Taiwan, its record-breaking military buildup and its efforts to dominate the critical technologies that will shape the world’s future. Over the long run, the Chinese challenge will most likely prove more manageable than many pessimists currently believe—but during the 2020s, the pace of Sino-American conflict will accelerate, and the prospect of war will be frighteningly real. America, Brands and Beckley argue, will still need a sustainable approach to winning a protracted global competition. But first, it needs a near-term strategy for navigating the danger zone ahead.

The United States has been the world's dominant power for more than a century. Now many analysts believe that other countries are rising and the United States is in decline. Is the unipolar moment over? Is America finished as a superpower? In this book, Michael Beckley argues that the United States has unique advantages over other nations that, if used wisely, will allow it to remain the world's sole superpower throughout this century. We are not living in a transitional, post-Cold War era. Instead, we are in the midst of what he calls the unipolar era—a period as singular and important as any epoch in modern history. This era, Beckley contends, will endure because the US has a much larger economic and military lead over its closest rival, China, than most people think and the best prospects of any nation to amass wealth and power in the decades ahead. Deeply researched and brilliantly argued, this book covers hundreds of years of great power politics and develops new methods for measuring power and predicting the rise and fall of nations. By documenting long-term trends in the global balance of power and explaining their implications for world politics, the book provides guidance for policymakers, businesspeople, and scholars alike.
