In his latest message, Donald Trump announced the launch of what he called “the most crushing economic operation ever conducted against any country” and wrote: “This will be economic warfare and isolation on an unprecedented scale.” He threatened that any country allowing its financial institutions, businesses, airports or government entities to provide “any kind of lifeline” to Iran would face “massive economic consequences.” Trump also targeted oil sales, swap lines, cash transfers, exchange houses, ship registrations and front companies, concluding: “This will be an Economic D-Day.”
The military term D-Day refers to the start date of a major and decisive operation and, for the public, is most associated with 6 June 1944, the beginning of the Normandy landings and the large-scale Allied invasion of Europe. Therefore, when Trump refers to an “Economic D-Day”, he is attempting to evoke the beginning of a full-scale economic assault against Iran; an attack that would use sanctions, oil, banking, shipping and pressure on financial networks instead of missiles and bombs.
However, behind this aggressive rhetoric lies a more important reality: Trump is once again repeating the same miscalculation he made on 28 February.
At that time, the US and the Israeli regime entered the war based on the assessment that Iran’s ability to respond, resilience and capacity to withstand pressure had been severely weakened, and that a major military strike could force Tehran into collapse, retreat or acceptance of Washington’s demands. Trump even went so far as to claim that he would determine Iran’s future leader. However, the full-scale and intense war against Iran not only failed to produce the outcome expected in Washington, but now, following the US failure on the military front, Trump has shifted from declaring victory to announcing the start of an “economic war” and returning to the same methods used by his predecessors, whom he had strongly criticized.
This shift itself demonstrates a change in the battlefield. Trump, who was expected to alter the equation with Iran through military power, has now returned to the same tools of sanctions and economic pressure; with the difference that this time as well, he has underestimated Iran’s capabilities and is entering another uncertain arena.
On the other side, the costs of this path for the US cannot be ignored. US national debt has now exceeded $40tn, while debt servicing costs have become one of the heaviest items in the federal budget, placing serious pressure on the country’s political, economic and even military structures. At the same time, the US energy market has come under pressure. Diesel prices have reached around $5.47 per gallon, approaching historic highs. The Financial Times has reported that rising diesel prices have increased transportation, agricultural and production costs, transferring inflationary pressure across the wider economy.
Diesel is particularly significant because, unlike petrol, it is directly linked to the cost of transporting goods, trucking, agricultural machinery, construction and supply chains. Therefore, higher diesel prices do not simply mean more expensive fuel; they lead to increased production and transportation costs and ultimately higher prices for consumer goods. At a time when the US congressional midterm elections are approaching, such pressure could carry a heavy political cost for the Trump administration. Rising petrol prices have already placed considerable pressure on American households, with estimates indicating that US consumers have paid tens of billions of dollars in additional costs.
From this perspective, “Economic D-Day” is not necessarily a sign of Trump’s strength; rather, it is a clear sign of his attempt to compensate for failing to achieve results on the military front. Given his mistaken assessment of Iran’s economic capacity, trade networks and resilience, similar to his flawed military calculations before entering the war, his latest move is unlikely to produce the outcome Washington seeks.
Trump once underestimated Iran’s ability to respond, resulting in a war that failed to achieve his declared political objectives and ended in a significant setback. Now, the same miscalculation is being repeated in the form of an “economic war.”
This time as well, the reality of Iran differs from Trump’s calculations, and Economic D-Day is not the day of Iran’s surrender, but rather the beginning of a second strategic defeat for Trump and an escalation of the crisis for himself, particularly on the eve of an election in which the economy and fuel prices could become the defining issues.
