destined for war

The phrase comes from Harvard political scientist Graham Allison's 2017 book Destined for War: Can America and China Escape Thucydides's Trap?, which popularized the concept of the Thucydides Trap. Allison draws on the ancient Greek historian Thucydides, who wrote in History of the Peloponnesian War that "it was the rise of Athens and the fear that this instilled in Sparta that made war inevitable."

Allison's core claim is structural: when a rapidly rising power threatens to displace an established ruling power, the resulting anxiety and miscalculation often produce war. His Belfer Center research project examined 16 historical cases over the past 500 years in which a rising power challenged a ruling one; by Allison's count, 12 ended in war and only 4 were resolved peacefully. Cited cases include Habsburg Spain vs. emerging England in the 16th century, France vs. Britain in the Napoleonic era, and most prominently Germany's rise vs. Britain before 1914.

The book applies this framework to U.S.–China relations, arguing that without deliberate statecraft, structural pressures over Taiwan, the South China Sea, trade, and technology could push Washington and Beijing toward conflict. Allison does not claim war is literally inevitable; he argues the historical base rate should alarm policymakers into pursuing strategic adjustment, summits, and clearer red lines.

The thesis has been widely debated. Critics including Arthur Waldron, Ian Buruma, and scholars at the Journal of Chinese Political Science argue that Allison's case selection is loose, that several "wars" predate any meaningful concept of power transition, and that economic interdependence and nuclear deterrence make the 21st-century dyad fundamentally different. Even Thucydides scholars note that Athens-Sparta involved alliance entanglement, not a clean dyadic transition.

Despite the criticism, "destined for war" and "Thucydides Trap" have entered mainstream foreign-policy vocabulary. Xi Jinping referenced the trap publicly during a 2015 Seattle visit, urging that both sides work to avoid it — evidence the framing now shapes elite discourse on both sides of the Pacific.
