War is expensive. That’s not a revelation. But when the Trump administration briefed Congress behind closed doors on the cost of the first week of the Iran conflict, the number still managed to land like a punch: roughly $11 billion in seven days, and the loss of American servicemembers’ lives that no dollar figure can account for.
The question that number raises isn’t whether the conflict is justified — that’s a separate debate. The question is what $11 billion per week means for a country already struggling under the weight of crumbling roads, an aging power grid, and energy prices that are squeezing working families to the breaking point.
A New Refinery — And Then Some
Consider this: President Trump recently announced that the first major new oil refinery in the United States in decades will be built in Brownsville, Texas. The America First Refining project will process up to 168,000 barrels per day and is expected to create thousands of jobs. The construction cost? An estimated $3 to $4 billion.
In other words, one week of the Iran war could fund two or three such refineries — the kind of investment that would do more to stabilize American energy prices long-term than any military engagement in the Middle East. Trump has touted the Brownsville project as a way to reduce the national deficit by $300 billion over its lifespan. Imagine what replicating that model could accomplish.
Roads and Bridges on the Brink
America’s infrastructure isn’t just aging — it’s failing. The American Society of Civil Engineers gave the country a cumulative “C” grade in its 2025 Infrastructure Report Card. The electrical grid earned a “D.” Seventy percent of the nation’s transformers are 25 years or older, and the backlog of deferred maintenance on roads and bridges alone stands at $105 billion.
The collapses tell the story in human terms — Minneapolis, the Pacific Northwest, Miami, Washington D.C., Pittsburgh. Each one a reminder that deferred maintenance eventually comes due, and the bill arrives in lives lost and communities disrupted.
The Trump administration has been making progress — Secretary Duffy has announced billions in road and bridge repair funding, and the president signed an appropriations package boosting highway funding significantly. But $11 billion in a single week of foreign conflict dwarfs those investments and highlights the stark trade-offs involved.
The Nuclear Question
Then there’s the matter of nuclear deterrence. The Congressional Budget Office estimates the U.S. will spend roughly $95 billion per year over the next decade to modernize its nuclear arsenal. An $11 billion injection would cover more than 11 percent of one year’s costs — meaningful progress on the weapons systems that ultimately underwrite American security far more reliably than any single regional conflict.
The Bottom Line
None of this is to say the Iran conflict is without strategic purpose. The Strait of Hormuz situation is a genuine threat to global energy security, and there are compelling arguments for a forceful American response. But fiscal conservatives have always understood that every dollar spent abroad is a dollar not spent at home — and at $11 billion per week, the opportunity cost is staggering.
Americans are already dealing with elevated gas prices, inflation that hasn’t fully receded, and an economy where working families feel the squeeze every single day. The war may be necessary. But pretending it comes without a domestic price tag isn’t conservatism — it’s fantasy.
