The nasty tariff war sparked by U.S. President Donald Trump has triggered fears of the “Thucydides Trap” haunting modern geopolitics, invoked to frame US-China rivalry as an inevitable clash between a rising power and an established one.
Graham Allison’s analogy, drawn from the Peloponnesian War, warns that China’s ascent could mirror Athens’ challenge to Sparta, making conflict unavoidable. Yet this framing distorts Thucydides’ true message – and risks becoming a self-fulfilling prophecy.
For starters, Thucydides did not write a playbook for power transitions; he penned his poignant observations of an avoidable tragedy. His History of the Peloponnesian War explores how human folly – hubris, fear, arrogance and miscalculation – drove Athens and Sparta to ruin.
The conflict was not predetermined by structural forces but ignited by leaders who weaponised insecurity, misread rivals, and succumbed to pride. Thucydides’ warning lies not in military inevitability but in the perils of poor judgment.
When he wrote, “Ignorance is bold and knowledge reserved,” he condemned the reckless confidence of leaders who mistake bluster for strategy.
Modern policymakers, however, wield the “Thucydides Trap” as a pseudo-scientific law, justifying hawkish posturing and military escalation. By treating war as a foregone conclusion, they erode diplomatic creativity and amplify the very fears that Thucydides cautioned against.
China’s rise need not mirror Athens’ downfall, yet the narrative of inevitability narrows options: defense budgets swell, rhetoric hardens, and dialogue atrophies. Allison himself stressed that war is likely, not fated—yet his caveat is drowned out by those eager to weaponize his analogy.
Moreover, the true tragedy lies in misreading history.
Thucydides’ account brims with moments where restraint might have averted disaster. For example, Sparta’s fear of Athenian power was matched by Athenian overreach, as both sides spiraled into hostility.
Today, the US and China risk replicating this dance: Beijing’s assertiveness feeds Washington’s paranoia, while America’s containment strategies fuel China’s siege mentality. As Thucydides noted, “The strong do what they will, the weak suffer what they must” – a lament, not a playbook, underscoring how unchecked power breeds injustice and chaos.
In my view, escaping the trap demands rejecting fatalism. It requires leaders to prioritise empathy over ego, to distinguish posturing from prudence, and to recognise that power transitions need not end in bloodshed.
The lesson of Thucydides is not that war is unavoidable, but that it becomes probable when fear eclipses reason and good judgement. In this context the US and China still have a choice: Will they heed history’s warning, or become its next tragic protagonists?
