The Donald Trump administration wanted to present the war with Iran as a limited operation with a clear military objective and manageable political costs. Eleven weeks after the start of operations, however, the picture emerging in Congress is very different.
The Pentagon now acknowledges that the cost of the war has reached approximately $29 billion. Just two weeks earlier, the estimate stood at $25 billion. The difference is not merely an accounting discrepancy. It reflects rising equipment replacement costs, repairs, operational expenses, and the reality of a conflict that, despite official assurances of a ceasefire, continues to consume military, financial, and political resources.
The problem for the White House is not only how much has already been spent. It is that no one at the Pentagon is clearly stating how much more will be needed.
Defense Secretary Pete Hegseth appeared before Congress to defend a defense budget approaching $1.45 trillion. Yet instead of providing a clear timetable for the emergency war funding package, he repeatedly avoided answering. He did not specify the amount required, when the request would be submitted, or whether the administration considers the war effectively over or merely paused in a fragile interim phase. That uncertainty is precisely where the political fracture in Washington is emerging.
A war that “ended” but continues to cost billions
The White House line is that hostilities with Iran have ended because a ceasefire exists. But the facts presented during congressional hearings make that claim difficult to sustain.
Fifteen thousand American troops remain deployed in the Middle East. More than 20 warships are still operating. The naval blockade remains active. In the Strait of Hormuz, tensions continue to affect shipping, insurance markets, fuel prices, and the global supply chain.
Republican Senator Lisa Murkowski raised the issue in terms that reflect broader concerns within the president’s own party. When thousands of troops are forward-deployed, dozens of warships remain active, and a blockade is still in effect, she argued, it becomes difficult to claim that hostilities have truly ended.
The wording matters. If the war is considered ongoing, Congress has a stronger institutional argument for demanding explanations, authorization, and oversight. If it is considered over, the White House can argue it is merely managing a military presence and a negotiation process.
The Trump administration appears to prefer the second interpretation. Congress—or at least part of it—no longer seems willing to accept that without objection.
The costs that still have not been counted
The official estimate of $29 billion is already enormous, but it is incomplete.
Pentagon comptroller Jay Hurst stated that the figure does not include repair costs for more than a dozen American military bases damaged by Iranian attacks. As he admitted, the Pentagon still does not know exactly how those facilities will be rebuilt and therefore cannot produce a reliable estimate.
In other words, the $29 billion represents only the known burden so far—not the final bill.
This is the most politically difficult aspect of the issue. Wars rarely cost what is initially projected. They cost what is eventually required to sustain operations, cover losses, replace weapons, repair bases, move forces, protect supply lines, and restore deterrence in other theaters.
And this war, according to Washington’s own admissions, has already diverted American military assets from Europe and Asia to the Middle East.
The ammunition question
Pete Hegseth attempted to downplay concerns about ammunition shortages, calling fears of depleted stockpiles “foolishly” exaggerated and “unhelpful.” He insisted that the Pentagon knows exactly what it possesses and has enough for current needs.
But that statement clashes with the logic of the very budget he is defending. The Pentagon’s request includes major funding increases for replenishing ammunition. The administration says there is no severe depletion problem, yet simultaneously seeks historic levels of funding to rebuild stockpiles heavily used during the conflict.
The military reality is more complicated than the political messaging. The United States may still have sufficient resources for its current missions. That was also the position of General Dan Caine, citing updates from senior commanders worldwide.
But “sufficient ammunition for what we are doing today” does not necessarily mean “comfortable strategic reserves for everything that could happen tomorrow.”
The war with Iran is not taking place in isolation. It is unfolding while Washington still views Russia as a long-term threat in Europe and China as its primary strategic competitor in the Indo-Pacific. Every missile, every bomb, every interception, and every transfer of military material to the Middle East carries costs elsewhere.
This is the point at which a military operation becomes a global balance problem.
Congress demands accountability
Discomfort is not limited to Democrats. Republican lawmakers are also pressing the administration to submit its emergency funding request quickly.
Republican Representative Ken Calvert, chairman of the House Defense Appropriations Subcommittee, told Hegseth that it would be better for the supplemental package to arrive “sooner rather than later.” His reasoning was straightforward: the sooner Congress knows what the administration wants, the sooner political and budgetary negotiations can begin.
Hegseth responded vaguely: “Whatever we determine we need, we will submit.” But he did not say when, how much, or under what operational assumptions.
In reality, the Trump administration appears intent on keeping its options open. It wants funding, but not necessarily the full political oversight that comes with it. It wants flexibility to restart operations if negotiations collapse. It wants to claim the ceasefire is holding while still maintaining escalation plans.
Hegseth himself admitted as much. The administration, he said, has plans for escalation if necessary, plans for troop withdrawals, and plans for shifting military assets. That is not the language of a war that has definitively ended. It is the language of a conflict that has frozen without being resolved.
The battle over authorization
Behind the debate over billions of dollars lies a deeper institutional question: who decides on war?
The Trump administration has made clear that it does not intend to seek new congressional authorization for continuing or resuming operations against Iran. Hegseth invoked presidential powers under Article II of the Constitution, arguing that the president already possesses all necessary authority.
That is the classic presidential argument during wartime: the president as commander-in-chief, while Congress informs itself, funds operations, protests, but rarely halts executive action once military operations have begun.
But here there is an important difference. The scale of involvement, the costs, the duration, the blockade of the Strait of Hormuz, and the impact on global markets make it increasingly difficult to describe the conflict as a limited operation.
If the United States maintains a large military force in the region, if the ceasefire could collapse, if the administration has ready escalation plans, and if costs continue rising by billions, then the question of authorization is not procedural—it is political and constitutional.
The gamble of bypassing Congress
Hegseth has hinted that the Pentagon could partially rely on budget reconciliation procedures to finance defense needs. Put simply, the administration could attempt to pass critical spending measures in ways that limit Democrats’ ability to block them in the Senate.
It is an institutional maneuver, but not without risks. Republican Representative Tom Cole, chairman of the House Appropriations Committee, warned that such a strategy depends on political support in Congress—and that support is far from guaranteed.
This may be the most revealing aspect of the hearings. Resistance is not coming only from Democrats. It is also coming from Republicans concerned about the fiscal burden, institutional bypassing, and the absence of a clear exit strategy.
Republican Senator Susan Collins posed the question many in Washington are asking: did the administration anticipate that Iran might close or threaten the Strait of Hormuz, triggering spikes in gasoline, heating oil, and diesel prices?
The answer was not reassuring. General Caine declined to reveal what advice he gave the president. Collins responded that it appears there is a different plan almost every day.
Trump’s real problem
Trump continues to present confrontation with Iran as historic and necessary. When pressured about the cost, Hegseth countered with a question of his own: what is the cost of allowing Iran to acquire a nuclear weapon?
Politically, that is the administration’s strongest argument. It shifts the debate from billions of dollars to existential risk, from budgeting to security, from skepticism to a stark dilemma: pay now or pay much more later.
But that argument has limits. As the war drags on, as the ceasefire remains uncertain, as the blockade continues, and as costs rise, the central question is no longer whether Iran posed a serious threat. It is whether the American government has a clear plan for what comes next.
A war is not judged only by whether it begins with a strong argument. It is judged by whether it ends with politically manageable costs, military recovery, and strategic gain.
Today, Washington has not convinced many observers that it has reached that point.
The war with Iran may no longer be in its hottest phase, but it has already entered its most difficult one: the phase of reckoning. And that reckoning is not merely financial. It is military, institutional, and political.
