Xi’s “Thucydides Trap”

When Chinese leader Xi Jinping sat down with President Trump this year, he reached for an old Greek war to describe a very modern problem. He asked whether China and the United States could “overcome the Thucydides Trap” and invent a new way for great powers to live together. In Washington he went further and said the trap “can be overcome.” It sounded statesmanlike. It was also a sales pitch.

The phrase comes from Thucydides, the Athenian soldier-historian who wrote the history of the Peloponnesian War. In the fifth century B.C., Athens rose as a naval empire after the Persian Wars. Sparta was the established land power of Greece. Thucydides’ famous line was that the truest cause of the war was “the rise of Athens and the fear that this instilled in Sparta.” Immediate quarrels over small cities and trade decrees mattered. The deeper force was a power shift. A rising state wanted more say. The ruling state feared being displaced. Fear plus ambition made a general war more likely.

Harvard’s Graham Allison popularized “Thucydides’s Trap” in the 2010s and applied it to China and America. He counted 16 cases over 500 years in which a rising power threatened a ruling one. Twelve ended in war. Four did not, including the U.S.–Soviet Cold War and America’s own rise past Britain. The original point was not destiny. It was a warning: structural stress makes catastrophe easy. Both sides can trip the wire.

Xi uses the same words with a different moral. In his telling, China is the legitimate rising power and the United States is the anxious and declining incumbent. The danger is that Washington, out of fear, will try to block China’s rise—especially over Taiwan. The implied assignment is therefore one-sided. America should accept a “new paradigm” of major-country relations. The two nations should be “partners, not rivals.” Competition should be a “race of catching up,” not a “wrestle” in which one side wins. Militaries should talk so an accident does not become a war. China’s “national rejuvenation” and “making America great again,” he said, can go hand in hand. Handle Taiwan “prudently.” Oppose “Taiwan independence.” Do not let that question push the two countries into a “clash or even conflict.”

That is a request that the United States stop treating China as a problem to be contained and start treating it as a peer whose red lines must be respected. It is not a full reading of Thucydides. Athens was not a passive victim of Spartan nerves. It was building an empire. Sparta was not only paranoid. It was watching a rival convert an alliance into domination. The trap is rise AND fear, ambition AND reaction.

Nor is today’s China merely a workshop that wants a seat at the table. A country can get rich and still behave like a normal trader. Beijing has used its rise in ways that inflict harm inside the United States, not just across the Pacific.

Start with fentanyl. Chinese chemical firms supply the great majority of the precursor chemicals Mexican cartels turn into the drug that has killed hundreds of thousands of Americans. China banned finished fentanyl-class drugs at home after 2019 and it's police state enforces it with brutality. It has been far slower to crush an export industry that profits from American deaths. Congressional investigators found tax rebates and other incentives that covered fentanyl-related materials, online sales with little fear of punishment, and cases in which U.S. leads were not met with serious help. That is not the same as a signed order from Xi to poison Ohio. It is also not “security.” A government that can jail a blogger can police a precursor plant. China openly permits this activity, if not encourages it.

Then there is political warfare on our soil. The Chinese Communist Party’s United Front system does not exist to admire the First Amendment. It exists to co-opt friends of Beijing and silence enemies of the Party—Falun Gong practitioners, Hong Kong activists, Uyghurs, Taiwan supporters, and Chinese students who step out of line. FBI officials have called the campaign to shut down dissent in America aggressive and widespread. That is the opposite of “supporting American political debate.” It is an attempt to import the Party’s speech rules into American cities, campuses, and diaspora life. Influence work also tries to shape local officials, business groups, and media so that criticism of the CCP becomes costly.

Xi’s trap language asks Americans to treat all of this as manageable rivalry: talk more, compete nicely, stay off Taiwan. The Greek story is bleaker. Athens and Sparta destroyed the system they were fighting to lead. Sparta “won.” Both were exhausted. A later power picked up the pieces.

Americans can want peace without accepting Xi’s assignment of roles. China is rising. The United States is the established power, and clearly declining. Fear is real. So is agency. Overcoming the Thucydides Trap is a worthwhile ambition but it doesn't mean we need to accept our own decline. Reagan showed us that American reinvigoration and thwarting the rise of foreign enemies without war IS an achievable outcome. It requires the right leadership and pushing back on the condescending rhetoric of the very adversaries who would have us kneel before them. We clearly have some work to do on both fronts.
