Twenty-one miles stand between civilisation and catastrophe. CHOKE reveals the geography the world's most powerful nations are desperate to control.It begins at 03:47 on a Tuesday morning. On the bridge of the Doha Star, a captain watches his AIS screen in silence as, one by one, every ship signal in the Strait of Hormuz disappears. Within seventy-two hours, London underwriters have withdrawn war-risk cover for the entire Persian Gulf. Within a week, oil prices have doubled. Within a month, the cascading consequences are being felt at petrol stations in California, in emergency cabinet sessions in Tokyo, and in desperate diplomatic calls from Islamabad to Riyadh. The strait has not been closed by a navy. It has been closed by geography, and by the cold arithmetic of asymmetric warfare.This is the world David G. Oldham maps in CHOKE, a work of rigorous geopolitical analysis that opens with a viscerally dramatised near-future scenario before pulling back to reveal the strategic logic that makes such a crisis not merely possible, but probable. Drawing on military history, energy economics, and investigative journalism, Oldham demonstrates that the great chokepoints of the modern world, narrow waterways, undersea cables, semiconductor fabrication plants, and rare-earth supply chains, are multiplying in number and increasing in fragility, not declining.From the Persian commanders who understood the tactical genius of Thermopylae to the Ottoman sultans who taxed European trade through the Dardanelles, the logic of chokepoint control is as old as recorded strategy. What has changed is the cost of disruption. A twenty-thousand-pound drone forcing a two-million-pound interception. A handful of Houthi missiles rerouting the entire global container fleet around the Cape of Good Hope. The geography has not become less relevant in the digital age. It has become more dangerous.CHOKE moves beyond the familiar maritime straits, Hormuz, Suez, Malacca, the Bosphorus, to chart the new generation of chokepoints reshaping twenty-first-century power. The Taiwan Strait is not merely a flashpoint between two governments; it is the single passage through which the world's most advanced semiconductors must travel. The handful of undersea cable landing stations that carry ninety-five per cent of global internet traffic are as strategically significant as any naval base. The rare-earth processing facilities concentrated in a single country represent a chokehold on the green energy transition itself. Geography, Oldham argues, is not a constraint that technology is dissolving. It is a constraint that technology is multiplying.Written for readers who want to understand the world as it actually works rather than as politicians describe it, CHOKE combines the narrative immediacy of crisis journalism with the analytical depth of grand strategy writing. No specialist knowledge is required, only the willingness to follow an argument wherever the evidence leads, including to some deeply uncomfortable conclusions about the vulnerability of the systems that sustain modern life.If the map is fighting back, this is the book that explains how, and what comes next.Fans of Tim Marshall's Prisoners of Geography, Robert Kaplan's The Revenge of Geography, and Peter Zeihan's geopolitical writing will find in CHOKE the most urgent and immediately relevant contribution to the genre since the Houthi disruptions of the Red Sea demonstrated, in real time, that chokepoint vulnerability is not a thought experiment. It is the defining strategic reality of our age.
