America reaches its 250th anniversary not as a fallen hegemon, but as the dominant centre of global hard power, monetary power, and frontier innovation. It still sits astride the world’s resource base through energy, agriculture, and continental depth; it still issues the reserve currency at the core of global trade and finance; and it still leads the race to build artificial intelligence (AI) as the next digital platform. Yet precisely because American power remains so large, the visible breakdown of the post–Second World War rules-based order has become impossible to ignore. To anyone who has read German historian and philosopher Oswald Spengler’s The Decline of the West (1918), this is not a surprise but a pattern: history is not a straight line of progress. Instead, it is the record of civilizations that rise as living cultures harden into systems and eventually exhaust the moral energy that made them great in the first place. America did not choose this time, but it has been born into it.

Winston Churchill, as first lord of the Admiralty, tied Britain’s fate to Persian oil. United States President Donald Trump’s war in Iran, centred on Operation Epic Fury, could do the same for the West by removing Iran’s nuclear shadow, resetting oil toward US$60, and finally unlocking a modern peace dividend.
