Hegseth tells Senate the US can reach what is buried under Pickaxe Mountain, and asks for $1.5 trillion to keep doing it

At roughly 20:25 UTC on 21 July 2026, inside a Senate Appropriations Committee hearing, Senator Dick Durbin asked War Secretary Pete Hegseth for an updated estimate of the cost of the war with Iran. Hegseth declined to put a number on it, telling the senator that the estimate depends on variables the executive branch is not ready to share. Minutes later, Senator John Kennedy asked whether the United States has the ability to destroy whatever is buried under Iran's Pickaxe Mountain. Hegseth replied that a lot of US capabilities are classified, then added that if anyone in the world can reach anything on earth, the United States can. The exchange, clipped by multiple open-source monitors, has since circulated as the clearest on-the-record statement yet of an administration positioning to escalate, not de-escalate, against Tehran.

The Pentagon is asking Congress to back a $1.5 trillion defence budget, Hegseth told the same panel earlier in the day, arguing the United States must significantly expand military spending. That request lands in a fiscal environment where the discretionary topline has been a perennial fight and where any figure north of a trillion dollars forces a rewrite of the Budget Control Act-era arithmetic. The request lands, too, against a stated war footing with Iran whose direct cost has now been conceded by the War Secretary himself to be unprintable in real time.

What the senators actually heard

Two distinct lines of questioning ran through the hearing. Durbin's exchange was about money: what is the bill, what is the duration, what does Congress need to know to write a supplemental. Hegseth's answer, in the version captured by Telegram monitors covering the room, was that the estimate is in flux and that the administration would brief the committee in the proper classified setting rather than on the record. The implicit message was that the war's price tag, like the war's targets, will be disclosed only after the fact.

Kennedy's line was about feasibility. Pickaxe Mountain, the colloquial name for the hardened tunnel complex under Mount Kolah Qaz, near Natanz in Isfahan province, is widely assessed by Western open-source analysts as one of the most deeply buried nuclear-related sites in Iran. Asking whether the US can destroy what is underneath it is shorthand for asking whether the US has the earth-penetrating conventional capacity, the bunker-buster inventory, the warhead yield, and the delivery profile to do it. Hegseth's reply, captured identically across at least four open-source channels, was that US capabilities are largely classified, and that if anyone in the world can reach anything on earth, it is the United States.

That formulation is a posture, not a plan. It does not commit to a strike, it does not commit against one, and it does not enumerate capability. It tells Tehran, Moscow, Beijing, and the Gulf that the classified budget for hardened-target defeat exists, is funded, and is pointed at the Iranian underground.

The $1.5 trillion arithmetic

The headline budget request is the second half of the story. A $1.5 trillion defence topline, if enacted, would represent a step change from the roughly $850 billion base the Pentagon operated under in recent fiscal years, before supplemental wartime spending. Hegseth framed the request as the cost of deterrence in an era in which peer competitors are expanding their own footprints. He did not, in the clips circulating on Tuesday evening, break the figure down between conventional procurement, nuclear modernisation, the Pacific posture, and the Middle East war.

That silence is the political substance of the hearing. Congress can refuse to authorise, refuse to appropriate, or appropriate with conditions. It cannot, in any realistic scenario, learn what the classified capabilities referenced in the Kennedy exchange actually are. The vote Congress is being asked to cast is therefore on a topline number whose component parts include line items the public will never see, attached to a war whose daily cost the executive will not print.

What the framing concedes

There is a counter-read worth taking seriously. The administration may be using the hearing to do something older than policy: to set price. By declining to put a number on the Iran war and by tying the request to a generic great-power frame, the executive is signalling that any supplemental, when it comes, will be written off against a $1.5 trillion base that Congress has already approved. From that vantage point, the war in Iran is folded into the deterrence story, not separated from it.

The structural pattern here is familiar. When a conflict is treated as a line item inside a larger posture budget, it becomes harder to debate on its own merits. The same mechanism let the post-2001 operations in Iraq and Afghanistan persist on supplemental after supplemental without ever forcing a clean vote on whether the underlying campaign made strategic sense. The Pickaxe Mountain exchange fits that pattern exactly: a wartime commitment, presented as a classified capability, attached to a multi-trillion-dollar base.

Stakes, and what is still unclear

If the $1.5 trillion topline clears, the US defence posture over the next decade will be the most explicitly Iran-coded it has been since 2003. Hardened-target defeat capability, currently centred on the GBU-57 Massive Ordnance Penetrator and its supporting delivery and intelligence architecture, would be funded against an inventory whose classified cost is the central unknown. Iran, for its part, has invested for two decades in the dispersion and burial of its most sensitive assets precisely to deny the United States a clean first-strike option, and Iranian state media will treat Hegseth's statement as confirmation of an American intent to use that option.

What the public record does not yet say is how the $1.5 trillion is to be split, what the Iran war has cost to date, what supplemental, if any, is queued behind the topline, and whether any committee member has been read into the capabilities Senator Kennedy asked about. The clips that surfaced on Tuesday night were partial. They tell the reader what the War Secretary was willing to say in open session. They do not tell the reader what he said behind closed doors, what the actual Pickaxe Mountain targeting picture looks like, or what the committee will do next. The hearing recessed without a vote. The next round of markups, and the next round of clips, will.

Desk note: Monexus has framed this story around the on-the-record exchange and the budget request, rather than around the underlying capability debate. Where Western wires read Hegseth's statement as a deterrent signal, the Iranian and Russian read will be that a strike is now closer, not further, and that read deserves equal weight in coverage of the regional fallout.
