In Steven Spielberg’s 1998 epic Saving Private Ryan, a squad of American servicemen is dispatched across war-torn France to retrieve a solitary soldier. The mission was a matter of policy: the military sought to preserve a family’s lineage after three of Ryan’s brothers were killed in action. In 1940, when families routinely raised four to six children, the state could plausibly ask for such sacrifice. By 2026, however, the arithmetic of war has shifted. In an age of one-child households and fractured families, almost every soldier resembles Private Ryan.
For the modern American voter, only an existential threat can justify the loss of a son. This demographic fact has quietly tethered the Pentagon. For decades Washington has preferred a form of “proxy-lite” warfare—leaning on air power and local allies, committing boots on the ground only once victory looked assured.
Any ground invasion of Iran was always destined to collide with this reality. Unlike the open deserts of Iraq, Iran’s Zagros Mountains form a natural fortress for irregular forces. Tehran also commands tools the Taliban and Saddam Hussein never possessed: precision-guided weapons. Anti-tank systems comparable to the American Javelin and shoulder surface-to-air missiles give insurgents a strike capability echoing Western air support. For a US administration sensitive to casualties, an occupation against a determined adversary is not merely difficult, it is politically impossible.

Despite President Trump’s campaign promises to avoid foreign entanglements, his strike campaign against Iran now looks like a breach of that pledge and is unpopular with much of his base. The limits on American power are no longer operational alone; they are electoral.
If the White House possessed a strategy, it rested on the assumption that overwhelming “Shock and Awe”—delivered by Tomahawk cruise missiles and stealth aircraft such as the B-2 Spirit and F-35 Lightning II—would force rapid capitulation. It was a misreading of the Persian state. Iran is no brittle autocracy bound to a single ruler. Power is dispersed through the Islamic Revolutionary Guard Corps, a vast military-commercial network embedded across the national economy.
On the battlefield, former American advantages have become liabilities. The spread of Chinese BeiDou and Russian GLONASS navigation has given Iran a precision-strike capability. Missiles such as the Fateh-110 and longer-range Shahab-3 can threaten American installations across the Gulf. It is now far more expensive to defend those bases—using Patriot and THAAD interceptors—than to attack them. Swarms of cheap Shahed-136 drones meanwhile drain interceptor stocks and have destroyed important radar installations.
At sea the balance is similar although the US possess overwhelming fire power. Iranian anti-ship missiles including the Noor family and updates models supplied by china have forced American carrier strike groups to operate 600km offshore. Were Tehran able to complete a satellite targeting kill chain, that distance might double, leaving even vessels such as the USS Gerald R Ford irrelevant to the course of the war.

Although American and Israeli aircraft suppressed Iran’s ageing air defences early, the achievement proved less decisive than advertised. Geography offered Tehran a more durable shield. Launchers concealed in the valleys and tunnels of the Zagros can be moved and fired again, allowing Iran to sustain a reduced but persistent tempo of missile launches despite allied air superiority.
In retaliation, Tehran has tightened pressure on the global economy. Every major oil exporter along the Gulf lies within range of Iranian missiles and drones. The Strait of Hormuz cannot easily be secured when swarms of drones and salvos of Fateh-class missiles threaten convoys regardless of escort.
Washington retains the ability to escalate with bombers, carrier aircraft and cruise missiles. Yet the strategic question remains unresolved: to what end? The regime shows little sign of collapse, and an implosion might scatter its arsenal among fanatical factions, complicating any day after scenario.
As the conflict drags on, economic pain among US allies deepens. Energy prices climb and governments reconsider reliance on American protection. In a world where precision missiles, drones and satellite navigation are no longer Western monopolies, the United States is discovering the limits of its military primacy.
