While Washington's war with Iran drags on, month after month, without any end in sight, the world is witnessing the very real limits of US global power. As President Donald Trump lurches repeatedly from threats of devastation to promises of peace, it's becoming increasingly clear that US military might is no longer capable of subduing even a mid-sized power like Iran, much less holding the rest of the world in its thrall.

Amid all the drama of air raids, drone strikes, and naval blockades, there are deeper geopolitical forces at play that lend a lasting historical import to events in the Persian Gulf—dynamics best seen by comparing two newspaper editorials with revealing similarities despite the 80 years separating their publication.

Writing in 1942, during some of Britain's darkest days in World War II, the editors of the venerable London Times looked far beyond the relentless German attacks on their forces in Egypt or the Nazi U-Boat sinkings of Royal Navy ships in the Atlantic to predict their empire's future with an uncommon prescience.

With its contradictory motto of "Imperium et Libertas" (Empire and Liberty), the vast British Empire, which still covered a quarter of the globe, had already become what those editors called "a self-liquidating concern."

Once the "temporary circumstances" that had allowed Britain's ascent — naval dominance, industrial preeminence, and "the relative weakness of rival states" — faded, that empire's "ultimate reliance on coercion" could no longer hold.

Ready for self-governance, Britain's many colonies, the editors suggested, would soon begin breaking away and so eclipse the empire. And that prediction couldn't have been more accurate. Within five years of that editorial's publication, the British Empire had already started to break apart.

Writing in a May 2026 edition of The New York Times, contributing editor Christopher Caldwell made a strikingly similar prediction about the future of US global hegemony. Under the provocative headline "America Is Officially an Empire in Decline," Caldwell noted some unsettling parallels between the fate of America today and Great Britain 80 years ago.

Back then, England was "deindustrializing, overcommitted, complacent," and found itself "essentially bankrupt" by the end of World War II. Apart from its "ill-fated attempt" to seize the Suez Canal from Egypt in 1956, however, it managed to decolonize in a successful fashion by giving up "territories it could no longer afford." As he points out, Britain even "wound up on reasonably good terms with its former colonial possessions."

At the start of his second term as president in 2025, Donald Trump, Caldwell continued, "had a chance of pulling off something similar" by withdrawing "to a less expansive sphere of influence" and "refocusing American attention on the Western Hemisphere." Caldwell considered that strategy potentially "workable" since "imperial systems, whatever you call them, last only as long as their means are adequate to their ends."

Instead of keeping to that plan, however, Trump "has overextended the empire dangerously" by his intervention in Iran, which has now become nothing less than a "watershed in the decline of the American empire."
