Destined for War: Can America and China Escape Thucydides’s Trap?

www.belfercenter.org May 15, 2026

When a rising power threatens to displace a ruling one, the most likely outcome is war. Twelve of 16 cases in which this occurred in the past 500 years ended violently.

A perilous trap but uncertain outcome

Today, an irresistible rising China is on course to collide with an immovable America. The likely result of this competition was identified by the great historian Thucydides, who wrote: “It was the rise of Athens and the fear that this instilled in Sparta that made war inevitable .”

But the point of Destined for War is not to predict the future but to prevent it. Escaping Thucydides’s Trap is not just a theoretical possibility. In four of the 16 cases, including three from the 20th century, imaginative statecraft averted war.

Can Washington and Beijing steer their ships of state through today’s treacherous shoals? Only if they learn and apply the lessons of history.

Will Washington and Beijing follow in the tragic footsteps of Britain and Germany a century ago? Or will they find a way to avoid war as effectively as the US did in crafting a Cold War strategy to meet the challenge posed by the Soviet Union? In Destined for War , eminent Harvard scholar Graham Allison explains why Thucydides’s Trap is the best lens for understanding the most critical foreign policy issue of our time.

Graham Allison is the Douglas Dillon Professor of Government at Harvard Kennedy School, former Director of Harvard Kennedy School’s Belfer Center for Science and International Affairs, and the best-selling author of Lee Kuan Yew: The Grand Master's Insights on China, the United States, and the World; Nuclear Terrorism: The Ultimate Preventable Catastrophe; and Essence of Decision: Explaining the Cuban Missile Crisis. Founding dean of the Harvard Kennedy School, Dr. Allison has served as Assistant Secretary of Defense and advised the secretaries of defense under every president from Reagan to Obama.

China and the United States are Heading 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. 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 sixteen times. War broke out in twelve of them. Today, an unstoppable China is approaching an immovable America. Both Xi Jinping and Donald Trump promise to make their countries “great again.” Business as usual is likely to produce history as usual. 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 twenty-first 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.
