Trump's Tariff Doctrine Was a Preference. The Iran War Made It a Necessity.

In November 2025, four months before the first American missile struck Iran, Donald Trump sat for a 60 Minutes interview and described his approach to conflict in terms no president had used before. He had stopped "eight wars," he said, and achieved 60 percent of those results "by threatening combatant nations with tariffs."

If you don't stop fighting, I'm putting tariffs on both of your countries and you're not gonna be able to do business with the United– — Donald Trump

The claim was characteristically large, but the method was real. That October, Trump had used economic leverage — tariff threats, sanctions relief, the promise and withdrawal of American market access — to broker ceasefires across six border disputes: Rwanda-Congo, Armenia-Azerbaijan, India-Pakistan, Kosovo-Serbia, Cambodia-Thailand, and Egypt-Ethiopia ^[1]. He framed it at the UN General Assembly as a mercantile alternative to the multilateral machinery he considered impotent. The same season, he launched a global trade war against more than 70 countries, pairing tariff escalations with military posturing in what aides described as a coordinated transactional foreign policy ^[2]. By December, his National Security Strategy had codified the shift: regional mediation, economic leverage, and the demand that allies pay for their own defense ^[3]. This was the preference, stated plainly and executed broadly, well before any missile was fired at Iran. Economic pressure was not a fallback. It was the doctrine. Then came Operation Epic Fury. In the first four weeks of the bombing campaign against Iran, the US military fired more than 850 Tomahawk cruise missiles and 1,000 interceptors ^[4]. The burn rate was extraordinary, and it exposed a vulnerability the doctrine had not accounted for: the United States could not sustain a kinetic war of any duration without draining the arsenal that underwrote its global posture. Officials warned that Middle East stockpiles were approaching a "Winchester" state — the military term for near-depletion — and that readiness gaps were opening in the Western Pacific ^[4]. The numbers that followed made the scale of the drain concrete. Senator Jeanne Shaheen testified before the Senate Foreign Relations Committee on March 25 that "in some cases, we have only about a quarter of the interceptors we need."

In some cases, we have only about a quarter of the interceptors we need. — Jeanne Shaheen

The war depleted up to half of key US missile stockpiles and roughly a third of the Tomahawk inventory ^[5]. The Joint Chiefs had warned about ordnance scarcity before the first strikes; Secretary of Defense Hegseth was later accused of misleading the president about the extent of the depletion ^[6]. The pivot from bombs to blockade was the moment the substitution became visible. The bombing campaign failed to dislodge the Tehran government. In April, Trump rebranded the effort "Economic Fury" — a naval blockade combined with comprehensive sanctions — and Treasury Secretary Scott Bessent made the logic explicit.

We are suffocating the regime, and they are not able to pay their soldiers. — Scott Bessent

The administration was now doing with ships and sanctions what it could no longer do with missiles. A planned strike was cancelled because the US had depleted nearly its entire global stockpile of high-precision offensive weapons ^[6]. The preference had become a constraint, and the constraint was physical. What followed was a gap between what the administration said and what it did that widened by the month. Hegseth insisted "we've got no shortage of munitions."

Press Secretary Karoline Leavitt claimed the military had "more than enough."

At the same time, Trump requested a record $1.5 trillion defense budget for 2027 and ordered Ford, General Motors, GE Aerospace, and Oshkosh to shift production lines to missiles and drones, placing the industrial base on what the Pentagon called a "wartime footing" ^[7]. That July, the Department of Defense announced a pivot to low-cost drone weaponry — a direct response to the cost-exchange nightmare of firing million-dollar interceptors at twenty-thousand-dollar Iranian Shahed drones ^[8][9]. In August, the administration signed $3 billion in framework agreements with Northrop Grumman and Lockheed Martin to triple PAC-3 interceptor production and quadruple THAAD output by 2030, under a program called "Arsenal of Freedom" that acknowledged stocks had been drawn down "by half or more" ^[10]. The denial and the rebuild were running on parallel tracks, and the rebuild told the truth. The allies read the situation faster than the administration admitted it. The US was forced to delay weapons deliveries to Baltic and Scandinavian NATO members — $640 million in outstanding Lithuanian orders, $160 million in Estonian deliveries — because depleted stockpiles could not meet both war-fighting and allied commitments ^[11]. Switzerland was told its Patriot batteries could face delays of up to seven years as Washington prioritized its own replenishment ^[12]. The US withdrew 5,000 troops from Germany and scaled back its NATO leadership role; Germany responded by planning what it called Europe's strongest conventional military by the mid-2030s ^[13]. In the Indo-Pacific, the retrenchment was starker. Trump transferred THAAD batteries from South Korea to the Middle East, told Taiwan it would have to pay for its own defense, and said "it is up to President Xi how he deals with Taiwan" ^[14].

it is up to President Xi how he deals with Taiwan — Donald Trump

When China escalated a grey-zone pressure campaign against Taiwan in June, the US response was reduced to a State Department call urging Beijing to "engage in meaningful dialogue" ^[15]. Japan and Australia, reading the signal, began building a $7 billion defense pact that did not include the United States ^[14]. None of these allies is behaving as though the American shortfall is temporary. They are building conventional militaries, forming their own pacts, and hedging against a gap measured in the years the US has already admitted — in its own production contracts — it cannot close before 2030. The economic-pressure doctrine was a choice when Trump described it on 60 Minutes. The Iran war made it the only tool left, and the allies have already priced in the difference.
