Thucydides's Trap

The centerpiece of President Trump’s conversation with Chinese President Xi Jinping on Thursday will doubtless be North Korea. Before their first meeting in April, Trump’s message to Xi was unmistakable: You solve this problem, or I will, and you won’t like the way I do it. Then, just after he served Xi and his wife chocolate cake at Mar-a-Lago, Trump excused himself and went to an adjacent room to announce that the U.S. was launching 59 cruise missiles against Syria. Message: I’m serious.

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.

The defining question about global order for this generation is whether China and the United States can escape Thucydides’s Trap. The Greek historian’s metaphor reminds us of the attendant dangers when a rising power rivals a ruling power—as Athens challenged Sparta in ancient Greece, or as Germany did Britain a century ago. Most such contests have ended badly, often for both nations, a team of mine at the Harvard Belfer Center for Science and International Affairs has concluded after analyzing the historical record. In 12 of 16 cases over the past 500 years, the result was war. When the parties avoided war, it required huge, painful adjustments in attitudes and actions on the part not just of the challenger but also the challenged.

The death of Lee Kuan Yew, the first prime minister of Singapore, is an occasion for reflection. Lee, who died Monday, was more than just his country's founding father. He did not just raise a poor, notoriously corrupt port city from the bottom rungs of the Third World to a modern First World state (with clean streets and clean government) in a single generation. He was also one of only two true grand masters of international strategy in the last half century (Henry Kissinger being the other), and a wise counselor to the leaders of the world.  (NOTE: This commentary was published by Caixin in Chinese.

Washington, D.C., is fast becoming an acronym for “Dysfunctional Capital.” Singapore, in contrast, has become the poster child for “the concept of good governance,” to quote the Financial Times’s obituary for the country’s longtime leader, Lee Kuan Yew, who was laid to rest on Sunday. For Americans in particular, this contrast presents a conundrum. On the one hand, Americans hold as a self-evident truth that their democracy is the best form of government. On the other hand, they see mounting evidence daily of Washington’s gridlock, corruption, and theatrical distractions, which makes their system seem incapable of addressing the country’s real challenges.
