As of March 2, 2026, Congress has not appropriated a single dollar for the military campaign against Iran. Operation Epic Fury, the joint U.S.-Israeli strike launched on February 28, 2026, was initiated without a congressional vote, without a formal legal justification from the White House, and without any dedicated funding bill. The operation is instead being financed from existing Pentagon budgets — money that was appropriated for other defense purposes — while lawmakers scramble to reassert their constitutional authority over war and spending. This is not a technicality.
Article I of the Constitution vests Congress alone with the power to declare war and to appropriate funds for military operations. The fact that a military campaign involving over 125 aircraft, 14 of the largest conventional bombs ever built, and at least 24 Tomahawk cruise missiles was launched without so much as a floor vote raises fundamental questions about the separation of powers. Three American service members have already been killed. This article breaks down the constitutional and fiscal dimensions of the Iran strikes: what Operation Epic Fury actually cost, why Congress was bypassed, what war powers resolutions are now on the table, and what taxpayers should understand about how their money is being spent without their representatives’ approval.

Why Hasn’t Congress Appropriated Funds for the Iran War?
The short answer is that Congress was never asked. The White House launched Operation Epic Fury unilaterally, notifying only the “Gang of Eight” — the top congressional leaders from both parties and both chambers — shortly before strikes began on February 28. There was no vote on an Authorization for Use of Military Force, no emergency supplemental spending request, and no public legal justification from the administration. Secretary of State Marco Rubio, in briefings with members of Congress, did not provide a full legal accounting of the authority under which the strikes were carried out. This stands in contrast to how the United States has historically funded major military operations. The wars in Iraq and Afghanistan were accompanied by supplemental appropriations bills — dedicated spending legislation that authorized specific funding above and beyond the regular defense budget.
No such bill exists for Operation Epic Fury. The chairman of the House Appropriations Committee, Rep. Tom Cole, has publicly called on Congress to pass a supplemental appropriations measure to at least replenish the munitions expended during the strikes, but even that limited step has not yet been taken. The distinction matters. When the Pentagon draws from existing budgets to fund an unauthorized operation, it pulls resources away from maintenance, training, readiness, and procurement programs that Congress actually voted to fund. Every Tomahawk missile fired at Iranian targets is a Tomahawk that will not be available for other contingencies — and replacing it requires money Congress has not allocated.
What Did Operation Epic Fury Actually Cost Taxpayers?
The numbers are staggering, even by Pentagon standards. Approximately 75 precision-guided weapons were used in the initial strikes, including 14 GBU-57 Massive Ordnance Penetrators — 30,000-pound bunker-buster bombs that had never been used in combat before. Each GBU-57 costs roughly $3.5 to $5 million. The 24-plus Tomahawk cruise missiles launched from a submarine run between $1.2 and $2.5 million apiece. Over 125 aircraft participated in the operation.
The munitions costs alone, before accounting for fuel, flight hours, intelligence support, personnel deployment, and naval positioning, likely run into the hundreds of millions of dollars. Kent Smetters, director of the Penn Wharton Budget Model, estimates that the total economic cost of the operation could reach as high as $210 billion when accounting for the broader economic fallout, including potential disruptions to oil markets, supply chains, and the cost of a sustained military posture in the region. Taxpayers for Common Sense has warned that any prolonged conflict with Iran would cost taxpayers dearly, and historical precedent supports that warning — the post-9/11 wars in Iraq and Afghanistan cost an estimated $8 trillion over two decades. However, if the operation remains limited to the initial strikes and does not escalate into a sustained ground or air campaign, the direct fiscal cost will be significantly lower than Smetters’ upper-end estimate. The critical variable is whether this is a one-time operation or the opening chapter of a longer war. Congress has no mechanism to constrain that escalation if it does not vote.
The Constitutional Crisis Over War Powers
The constitutional issue here is not subtle. The framers of the Constitution deliberately placed the war power in the legislative branch, not the executive. James Madison wrote that the executive branch is the branch “most interested in war, and most prone to it,” which is precisely why the power to declare war was given to Congress. The ACLU’s Christopher Anders put it bluntly: Trump “violated the Constitution by invading Iran because the Constitution is crystal clear on who has the authority to declare war and commit American service members to battle and that is Congress alone.” What makes this moment different from previous executive overreach — and there have been many, from Korea to Libya — is the scale. Operation Epic Fury killed Ayatollah Ali Khamenei, Iran’s supreme leader. This was not a limited retaliatory strike against a militia proxy or a one-off drone operation.
It was a decapitation strike against a sovereign nation’s head of state, combined with a comprehensive assault on that nation’s nuclear infrastructure and military capabilities. The potential for catastrophic escalation is enormous, and three U.S. service members have already paid with their lives. The White House has not publicly presented a legal justification for the strikes. Previous administrations have relied on arguments ranging from the 2001 Authorization for Use of Military Force to Article II commander-in-chief powers to justify unilateral action, but the Trump administration has not even offered that much. The silence itself is remarkable — it suggests either that no credible legal theory exists or that the administration has decided it does not owe Congress or the public an explanation.
What War Powers Resolutions Are on the Table — and Will They Work?
Two bipartisan war powers resolutions are now moving through Congress. In the Senate, Tim Kaine of Virginia and Rand Paul of Kentucky — a Democrat and a Republican who have long collaborated on war powers issues — have introduced a resolution that would require explicit congressional authorization before any further hostilities against Iran. In the House, Thomas Massie of Kentucky and Ro Khanna of California have introduced a parallel measure to halt unauthorized military action. Votes are expected mid-week during the week of March 2, but the political math is brutal. Even if the resolutions pass both chambers — which is not guaranteed, given that many Republicans are reluctant to publicly oppose a military operation carried out by a president of their own party — they would need two-thirds majorities in both the House and Senate to override the inevitable presidential veto.
That threshold is widely expected to be out of reach. The resolutions serve more as political statements and constitutional markers than as practical constraints on executive power. The tradeoff for members of Congress is stark. Voting for the war powers resolution means asserting legislative authority at the cost of being portrayed as undermining troops in the field. Voting against it means ceding the constitutional war power to the executive branch, potentially for a generation. This is the same dynamic that has eroded congressional war authority since the Korean War, and it shows no sign of resolving differently this time.
The Funding Gap and the Risk of a Blank Check
The most dangerous scenario from a fiscal accountability perspective is not that Congress refuses to fund the operation — it is that Congress eventually passes a supplemental appropriations bill with minimal oversight or conditions. This is what happened repeatedly during the wars in Iraq and Afghanistan, where emergency supplemental spending bills became vehicles for hundreds of billions of dollars in largely unscrutinized spending. Rep. Cole’s call for supplemental appropriations to replenish expended munitions is reasonable on its face — the military does need to replace the weapons it used. But a supplemental bill could easily become a much larger vehicle, funding not just munition replacement but ongoing operations, troop deployments, intelligence activities, and reconstruction efforts.
Without strict conditions, a supplemental becomes a retroactive blank check for an operation that was never authorized in the first place. There is also a related but separate funding fight happening simultaneously. The DHS appropriations bill is the only one of the 12 fiscal year 2026 spending measures that has not yet become law. That fight is consuming congressional bandwidth and political capital at exactly the moment when lawmakers should be focused on the constitutional and fiscal implications of a new war. The timing is not coincidental — divided attention serves the interests of an executive branch that would prefer Congress not look too closely at Iran.
What Advocacy Groups and Analysts Are Saying
The response from civil liberties organizations, think tanks, and advocacy groups has been swift. The ACLU has framed the strikes as a clear constitutional violation. The American-Arab Anti-Discrimination Committee has called on Congress to reject Operation Epic Fury and stop the war with Iran.
The Center for Strategic and International Studies has published analysis of the operation’s impact on Iran’s nuclear program, raising questions about whether the strikes actually achieved their stated strategic objectives or simply delayed Iranian nuclear ambitions while creating a host of new geopolitical risks. Taxpayers for Common Sense, a nonpartisan budget watchdog, has focused on the fiscal dimension, warning that a prolonged conflict would drain resources from domestic priorities and add substantially to the national debt. Their concern is not hypothetical — every major U.S. military engagement of the past 25 years has cost far more than initial estimates suggested, and the pattern of underestimation is so consistent that it should be treated as a feature of how wars are sold to the public, not a bug.
What Comes Next for Congressional Authority and Accountability
The next two weeks will determine whether Congress reasserts any meaningful role in this conflict or whether the legislature continues its decades-long retreat from its constitutional war powers. If the war powers resolutions fail to override a veto — as expected — the practical restraint on executive action will be almost entirely political, not legal. The only real lever Congress retains is the power of the purse, and whether lawmakers are willing to use it aggressively remains to be seen.
The broader lesson is one that transcends partisan politics. Whether one supports or opposes the strikes on Iran, the process by which they were authorized — or rather, not authorized — sets a precedent that will be available to every future president of either party. A constitutional power that is never exercised is a constitutional power that effectively ceases to exist. For taxpayers, the question is even more concrete: hundreds of millions of dollars in weapons have already been expended, a potential $210 billion in economic costs looms, and not a single elected representative cast a vote to approve any of it.
Conclusion
Congress has not appropriated a single dollar for Operation Epic Fury, and as of March 2, 2026, it has not authorized the military action either. The operation was launched unilaterally, funded from existing Pentagon budgets, and conducted without a public legal justification. Bipartisan war powers resolutions are advancing in both chambers, but they face near-certain failure to override a presidential veto. The constitutional and fiscal stakes could not be higher. What taxpayers and citizens should understand is that this is not merely a legal debate among constitutional scholars. It is about whether the elected representatives who control the federal budget have any say in whether the country goes to war and how much it costs.
The munitions alone run into the hundreds of millions. The broader economic impact could reach $210 billion. Three service members are dead. And Congress — the body the Constitution entrusts with the power to declare war and fund it — has not voted on any of it. That is not a partisan observation. It is a constitutional fact.
Frequently Asked Questions
Did Congress authorize Operation Epic Fury before the strikes began?
No. The White House launched the strikes unilaterally on February 28, 2026, notifying only the Gang of Eight — the top eight congressional leaders — shortly before operations commenced. No floor vote was held in either chamber.
How is the operation being funded if Congress didn’t appropriate money for it?
The Pentagon is drawing from its existing defense budget — funds that Congress appropriated for other purposes such as readiness, training, and procurement. No supplemental appropriations bill has been introduced or passed specifically for Operation Epic Fury.
How much has Operation Epic Fury cost so far?
Direct munitions costs likely run into the hundreds of millions of dollars, given the use of 14 GBU-57 bunker busters ($3.5–$5 million each), 24-plus Tomahawk missiles ($1.2–$2.5 million each), and over 125 aircraft sorties. The Penn Wharton Budget Model estimates total economic costs could reach as high as $210 billion.
What are the war powers resolutions currently in Congress?
A bipartisan Senate resolution led by Sens. Tim Kaine (D-VA) and Rand Paul (R-KY) and a bipartisan House resolution led by Reps. Thomas Massie (R-KY) and Ro Khanna (D-CA) both seek to require congressional authorization before further military action against Iran. Votes are expected mid-week of March 2, but are widely expected to fall short of a veto-proof majority.
Has the White House provided a legal justification for the strikes?
No. As of March 2, 2026, the White House has not publicly presented a legal justification. Secretary of State Marco Rubio did not provide a full legal accounting to members of Congress during briefings.
Were there U.S. casualties in the operation?
Yes. Three U.S. service members were killed during Operation Epic Fury.
