Defense Secretary claims Iran's military is destroyed—but five months in, the war costs $37.5B

July 22, 2026 · 11 min

Max Rivera & Clara Bennett

Five months into the U.S. war with Iran, Defense Secretary Pete Hegseth disclosed $37.5 billion in war costs to the Senate on July 21, 2026 — despite declaring Iran's military 'destroyed and combat ineffective' in March. The figure excludes U.S. base repair costs, and the White House has separately requested $87.6 billion more.

In mid-March 2026, approximately two weeks into the U.S.–Iran conflict, Defense Secretary Pete Hegseth publicly declared that Iran's military had been "destroyed" and rendered "combat ineffective" following an intense U.S.–Israeli air campaign called Operation Epic Fury.

About this episode

On March 14, 2026 — day 14 of the Iran war — Defense Secretary Pete Hegseth declared Iran's military 'destroyed and combat ineffective.' On July 21st, day 143, he sat before the Senate Appropriations Committee and disclosed $37.5 billion in war costs, while the White House simultaneously submitted an $87.6 billion supplemental funding request, $67 billion of it earmarked for Middle East operations. This episode works through the contradiction carefully. It examines what 'combat ineffective' actually means as a military term — a 90 to 95 percent reduction in missile and drone launch rates — versus what it implies to a public hearing it as a verdict. It traces the spending velocity: $11.3 billion in the first six days alone. And it puts the $37.5 billion in context, noting that the figure excludes military construction costs for damaged U.S. bases, a gap confirmed by CBS News through multiple sources. Drawing on Harvard Kennedy School's Linda Bilmes and the historical pattern of war cost underestimation — Vietnam's 1964 projection was $5 billion total; by 1968 annual costs hit $25 billion — the episode asks what happens when Congress authorizes a number with no exit condition attached. The July 21st hearing ended in a shouting match. This is what led there.

Frequently asked

How much has the U.S. war with Iran cost so far?

The U.S. war with Iran has cost at least $37.5 billion through July 2026, according to Defense Secretary Pete Hegseth's Senate testimony on July 21, 2026. That figure excludes military construction costs for damaged U.S. bases, making $37.5 billion a confirmed floor, not a ceiling.

Did Pete Hegseth say Iran's military was destroyed?

Pete Hegseth declared Iran's military 'destroyed and combat ineffective' around day 14 of the conflict, approximately mid-March 2026. The claim reflected a 90–95 percent reduction in Iranian missile and drone launch rates, but critics argue that tactical degradation is not the same as ending the conflict.

What is the $87.6 billion Iran war funding request?

The White House formally submitted an $87.6 billion supplemental funding request to Congress, with approximately $67 billion earmarked for Middle East military operations. The Office of Management and Budget submitted the request concurrent with Hegseth's July 21, 2026 Senate Appropriations Committee hearing on Iran war costs.

What did Iran do after the U.S. declared its military destroyed?

After the U.S. declared Iran's military combat ineffective in mid-March 2026, Iran struck commercial vessels in the Strait of Hormuz, broke a ceasefire, and resumed hostilities. By July 21, 2026, three American soldiers had been confirmed dead and nightly exchanges had resumed the week before Hegseth's Senate testimony.

Do war costs typically exceed initial government projections?

War costs historically far exceed initial projections, according to Harvard Kennedy School expert Linda Bilmes. The Vietnam War illustrates the pattern: 1964 projections estimated $5 billion for the entire conflict, but by 1968 annual costs alone reached $25 billion. Bilmes warns the same structural undercount applies to the Iran war's $37.5 billion figure.

Read transcript

Max Rivera: Hey, long week — I've been staring at this Hegseth testimony since Tuesday and I genuinely can't decide if I'm angry or just baffled.

Clara Bennett: Both are appropriate. Hand me the contradiction — say it out loud.

Max Rivera: Okay. So — mid-March 2026, Pete Hegseth stands up and says Iran's military is 'destroyed and combat ineffective.' That's day 14. Then on July 21st, he's in front of the Senate Appropriations Committee disclosing $37.5 billion in war costs. To fight the destroyed enemy. That's day 143.

Clara Bennett: And the $37.5 billion matters even more when you remember the first six days alone cost $11.3 billion. The velocity of spending was staggering from the jump.

Max Rivera: Eleven point three billion in six days — that's like, two billion dollars a day.

Clara Bennett: Exactly. Now, the Pentagon's early framing around Operation Epic Fury was designed to make that spending feel justified — 15,000-plus targets struck, Ayatollah Ali Khamenei killed on February 28th alongside the Israeli coordinated strikes. That's a decapitation. That's why 'combat ineffective' stuck.

Max Rivera: Khamenei killed on day one — I mean, that's genuinely significant. So you can see why someone looks at that and says 'we won.'

Clara Bennett: You can. But then Iran spent the next five months proving that decapitating the leadership and degrading launch capacity are not the same thing as ending a conflict. By July 21st, Iran had struck commercial vessels in the Strait of Hormuz, broken the ceasefire, and three American soldiers were confirmed dead — and Hegseth still needed $37.5 billion worth of explaining.

Max Rivera: But here's what I keep getting stuck on — 'combat ineffective' sounds like a verdict. Like the fight is over. Is that actually what the phrase means, or is that just... how it landed?

Clara Bennett: That's the precise problem. 'Combat ineffective' is a tactical assessment — it means their punch rate dropped, not that they stopped swinging. A 90 to 95 percent reduction in missile and drone launch rates is real. The data probably supported that in March. But saying your opponent's punch rate dropped 90 percent is not the same as saying the fight is over. Those are two completely different claims.

Max Rivera: One is a number. One is a conclusion.

Clara Bennett: Exactly — and Hegseth appears to have delivered both at once, in the same breath, and nobody flagged the category error in real time. Now by early April, the U.S. had 56,000 troops in the war zone — 50,000 on ships and bases, 4,500 Marines, 2,000 from the 82nd Airborne — with another 10,000 ground troops under consideration. That's not the footprint of a concluded fight.

Max Rivera: Wait — 56,000 troops in April, and the 'destroyed' declaration was mid-March? I mean — that's two weeks apart. That's not a lag, that's the same moment.

Clara Bennett: Right — and then Dan Caine, the Chairman of the Joint Chiefs, is sitting at that same July 21st Senate Appropriations Committee table with Hegseth. Both of them testifying. So this isn't one official going rogue with an optimistic read. The institutional assessment, at least publicly, held.

Max Rivera: Okay, but — Iran is hitting ships in the Strait of Hormuz, we're back to nightly exchanges the week before July 21st, and the tactical caveat is still doing a lot of work here. At some point does 'we degraded their capacity' just... stop mattering as an explanation?

Clara Bennett: In practice, yes. And I want to be careful — we don't have full visibility into the Pentagon's internal framing, so I'm not going to assert this was deliberate. But the structural effect is the same either way: Congress ended up funding what looks like two different wars under one 'combat ineffective' label.

Max Rivera: Two wars under one label — and that's actually the take I want to push back on, because there's a version of this going around where people say Ossoff was just doing partisan theater. That the whole July 21st hearing was a Democrat going after a Trump cabinet secretary for optics. And I think that's — wait, no, I think that's exactly wrong.

Clara Bennett: Test it. What's the strongest version of the theater argument?

Max Rivera: The strongest version is — Ossoff already knew the answer. He's on the Appropriations Committee, he's seen the numbers, the contradiction isn't a discovery, it's a gotcha. So the hearing is performance, not oversight.

Clara Bennett: That argument collapses the moment you look at the $87.6 billion supplemental request. The Office of Management and Budget formally submitted that alongside the hearing. $67 billion of it earmarked for Middle East operations. You cannot call oversight 'theater' when the administration is simultaneously asking Congress for $87.6 billion to continue the war it declared won.

Max Rivera: Eighty-seven point six billion — that's not a cleanup budget. That's a continuation budget.

Clara Bennett: In practice, yes. And the logic is irreconcilable. If Iran's military is destroyed and combat ineffective — Hegseth's own March framing — then what is the $67 billion for? You either won or you need $67 billion more. Those two claims cannot both be true at the same time. Ossoff surfaced a structural contradiction, not a partisan one. Trump was reportedly in a shouting match with a Republican senator over this same supplemental request — that's not a Democrat ambush, that's bipartisan alarm.

Max Rivera: A Republican senator. In a shouting match. With Trump. Over the war funding.

Clara Bennett: Right — and the $37.5 billion itself is already nearly $8 billion more than the May estimate. That's a 29 percent jump in roughly two months, with military construction costs for damaged U.S. bases still excluded from that figure. We should be honest — we don't know the full breakdown of the $87.6 billion yet. But the gap between 'destroyed enemy' and 'please fund this further' is not a matter of accounting. It's a logical contradiction.

Max Rivera: And that $37.5 billion — that's actually the floor, not the ceiling. What those excluded construction costs do to the real number, and what Linda Bilmes at Harvard Kennedy School says about where this historically ends up for ordinary Americans — that's the part that makes all of this significantly worse.

Clara Bennett: And that's not a small caveat. CBS News confirmed through two Democratic sources and a third party familiar with the figures that the $37.5 billion excludes military construction costs for damaged U.S. bases. So the actual floor is higher — we just don't know by how much.

Max Rivera: Wait — base repair costs aren't in the number at all?

Clara Bennett: Not according to those sources. And Linda Bilmes at Harvard Kennedy School would tell you that's entirely typical — not an anomaly. Her warning is structural: war costs consistently exceed initial projections, and the long-term costs linger for decades after hostilities end. Vietnam is the pattern. 1964 projections were $5 billion for the entire war. By 1968, annual costs alone were $25 billion.

Max Rivera: Annual. Not total. Annual.

Clara Bennett: Annual. So the question isn't whether the Pentagon miscalculated — they almost certainly did, and Bilmes would say that's baked in. The question is what it costs the people who never voted on any of this.

Max Rivera: Which is — I mean, that's the part that stands out. The $775 to $1,300 per household number. That's fuel costs, that's taxpayer exposure, that's what this war is already pulling out of an average family's pocket. And think about — a truck driver refueling on July 22nd, the morning after the Hegseth hearing. Gas is past $4 a gallon. He has no idea that oil spiking past $100 a barrel, that Iran's strikes on commercial vessels in the Strait of Hormuz — that those events are literally embedded in the price on the pump he's staring at.

Clara Bennett: And those Strait of Hormuz shipping disruptions appear in no Pentagon accounting line. They flow through supply chains invisibly. So the $37.5 billion isn't even trying to capture what ordinary households are already absorbing.

Max Rivera: So what do we watch for? Like — concretely, what's the tell that the real number is about to surface?

Clara Bennett: Watch when military construction gets added to the supplemental request — that's the moment Congress feels the gap. And watch whether Bilmes's pattern holds: if 2026 costs keep accelerating the way Vietnam did post-64, the $37.5 billion figure will look like the floor it is within months. We should be honest — we don't have the full breakdown yet. But the structural incentive to underdisclose is exactly what produced this gap in the first place.

Max Rivera: And that's — I mean, that's the reality. If Congress approves the $87.6 billion without anyone defining what 'done' looks like, they've just authorized a number with no exit condition attached to it. And then when the Pentagon returns in October with a higher figure — and the Council on Foreign Relations and Harvard Kennedy School are both flagging that the accounting methodology appears to be repeating the same historical undercount patterns — nobody can even say they weren't warned.

Clara Bennett: The hearing ended in a shouting match. Not a resolution. That's not a small detail — that's where Congress actually is right now on this. And I genuinely don't know whether they behave differently when they know wars exceed projections by three or four hundred percent. The evidence so far says no.

Max Rivera: Yeah. That's the question I'm left holding, honestly.
