China and the United States are headed toward a war neither wants. The reason is Thucydides’s Trap, a deadly pattern of structural stress that results when a rising power challenges a ruling one. This phenomenon is as old as history itself. About the Peloponnesian War that devastated ancient Greece, the historian Thucydides explained: “It was the rise of Athens and the fear that this instilled in Sparta that made war inevitable.” Over the past 500 years, these conditions have occurred 16 times. War broke out in 12 of them. Today, as an unstoppable China approaches an immovable America and both Xi Jinping and Donald Trump promise to make their countries “great again,” the 17th case looks grim. Unless China is willing to scale back its ambitions or Washington can accept becoming number two in the Pacific, a trade conflict, cyberattack, or accident at sea could soon escalate into all-out war.In Destined for War, the eminent Harvard scholar Graham Allison explains why Thucydides’s Trap is the best lens for understanding U.S.-China relations in the 21st century. Through uncanny historical parallels and war scenarios, he shows how close we are to the unthinkable. Yet, stressing that war is not inevitable, Allison also reveals how clashing powers have kept the peace in the past—and what painful steps the United States and China must take to avoid disaster today. —Houghton Mifflin Harcourt{chop}
