As of July 24, 2026, the United States finds itself once again on the edge of a decision that could reshape the Middle East, and this time the target has a name that sounds almost cartoonish for something so serious. Pickaxe Mountain. It is the informal nickname given to a fortified underground facility that Iran has been carving into a mountainside just south of its Natanz enrichment complex, and it has become the single most talked about flashpoint in a war between Washington and Tehran that has now stretched across days of continuous strikes. President Trump has repeatedly issued threats to bomb this under-construction Iranian nuclear site, which is buried deep beneath the mountain. The site sits close enough to Natanz that satellite imagery firms have photographed both facilities in the same frame, and the physical proximity has done nothing to calm nerves in a region already stretched thin by war. The Washington Post

The president has not been shy about his intentions. Speaking to reporters in the Oval Office, Trump said the United States would target Pickaxe Mountain, and he did so on a day marking ten straight days of strikes in an escalating war. His language was blunt and unmistakably threatening. He told the assembled press that the site would be hit soon and hit hard, and according to reporting from ABC News, Trump told reporters “we’ll be hitting that area pretty soon, and very heavily,” repeating a threat he had made against the site in recent weeks. This was not a slip of the tongue or an offhand comment. It was a repeated, deliberate signal, the kind of thing a president says when he wants an adversary and the watching world to take him at his word. ABC News + 2

What makes Pickaxe Mountain different from the litany of other targets hit during this renewed conflict is the specific worry attached to what may be stored inside it. The Wall Street Journal reported, and multiple outlets have since repeated, that Israeli intelligence believes Iran transferred centrifuges capable of enriching uranium to Pickaxe Mountain sometime last fall. Centrifuges are the spinning machines that separate uranium isotopes, gradually pushing a stockpile from reactor grade toward weapons grade, and their presence at a heavily fortified, deeply buried facility is exactly the kind of detail that turns an obscure mountain into a geopolitical flashpoint. When directly asked whether he believed the transfer had happened, the president did not deny it outright. Instead, Trump said Iran “may have” moved the centrifuges there, though he added the caveat that “we don’t have it on record.” He went further, suggesting the reporting could be accurate this time, and he was quoted as saying “maybe this one they have right,” about the newspaper’s account, though he tempered even that by insisting the equipment alone did not matter without the material to feed it. ABC News + 2

That distinction between equipment and material is one the president has leaned on heavily, and it is worth sitting with for a moment because it reveals how the administration is framing its own justification. Trump has said the U.S. would work to secure Iran’s stockpile of highly enriched uranium, which is believed to be close to 1,000 pounds and near weapons-grade purity, arguing that the military campaign’s success hinges on inhibiting Iran’s path toward an actual bomb rather than merely destroying buildings and equipment. In his words, quoted across multiple outlets, “we follow the material,” referring to the uranium itself rather than the tunnels or the machines that might process it. It is a rhetorical move that positions the administration as focused and precise, even as the practical reality of bombing a mountain is anything but surgical. ABC News ABC News

The facility itself has a longer history than the current news cycle suggests. According to reporting from Time, construction at Pickaxe Mountain, known in Iran as Kuh-e Kolang Gaz La, began back in 2020 after a fire at Natanz that Iranian officials attributed to sabotage. At the time, Iran said the new underground halls were meant to replace an above ground advanced centrifuge assembly facility that had been destroyed, according to the Institute for Science and International Security. That institute, a respected nonproliferation research group, has tracked the site closely through satellite imagery ever since, and its assessments carry weight in a debate otherwise dominated by political rhetoric. Nuclear policy expert James Acton of the Carnegie Endowment for International Peace told Time that the facility runs remarkably deep into the rock, explaining that “it’s a very deep facility. We don’t know exactly how deep, but it’s very likely at least 100 meters deep.” A hundred meters of rock is an extraordinary amount of overburden, and it is precisely the kind of depth that has kept the site untouched through two prior rounds of conflict. Time + 2

That history of restraint is itself notable. Researchers at the Institute for Science and International Security noted in a report that despite two separate wars, in 2025 and again this year, the tunnel facility at Pickaxe Mountain had not previously been targeted, apart from the destruction of a vehicle on a nearby spoil pile that was likely tied to air defense operations rather than the facility itself. That restraint appears to be ending now. David Albright, the founder of that same institute and a longtime nuclear weapons analyst, offered a blunt public assessment on social media, suggesting that the mountain is large enough to hold both a centrifuge enrichment plant and activities related to nuclear weaponization. He also floated an explanation for the shift in strategy, writing that officials had previously said the site was spared because nothing of sufficient value was believed to be inside it, and that assessment may have simply changed. Albright added another layer to his analysis, suggesting that Trump may be unwilling to leave Iran with an intact, deeply buried nuclear-related facility given signs the regime is working to rebuild its weapons capable infrastructure. Time + 3

There remains real uncertainty about what the site is actually for and how close it is to being usable, which is worth stating plainly rather than glossing over. The same ISIS researchers cautioned in a mid-July note that it remains unclear when Pickaxe Mountain could become operational based solely on satellite imagery, and it is similarly unclear whether Iran still intends to install a large scale centrifuge assembly facility there given the extensive damage already done to its broader centrifuge manufacturing capability. In other words, even the experts most invested in tracking this site openly admit they are working from inference and shadows on satellite photos, not certainty. That ambiguity does not make the threat imaginary, but it should temper how confidently anyone, including a sitting president, talks about what exactly sits under that mountain. CNBC

The broader military context makes all of this more urgent. This is not a hypothetical strike being weighed in isolation. It is happening amid what reporting describes as eleven straight nights of U.S. strikes on Iranian targets, including military operations centers, drone storage facilities, and logistics infrastructure aimed at degrading the country’s broader military capacity. Iran, for its part, has not been passive. Reporting indicates Iran has claimed responsibility for an attack on Amazon infrastructure in Bahrain, a strike that, whatever its actual scale, signals Tehran’s willingness to expand the conflict beyond its own borders and toward regional infrastructure tied to American commercial interests. Secretary of State Marco Rubio has also warned publicly that Iranian threats around the Strait of Hormuz risk triggering consequences far beyond the immediate battlefield, a warning that underscores just how easily this conflict could ripple outward into global shipping lanes and energy markets. This is the backdrop against which the Pickaxe Mountain decision is being made, a war that is already wide, already violent, and already testing the outer edges of regional stability well before a single bomb falls on that specific mountain. CNBC CNBC

Now to the fear that has been spreading fastest online and in private conversations alike, the idea that bombing this site, whether with a nuclear weapon or simply a very large conventional one, could itself trigger something resembling a nuclear explosion. This concern deserves to be taken seriously enough to actually examine rather than simply repeated as a talking point, because the honest answer, according to the people who study this for a living, complicates the popular fear considerably.

Start with the most extreme version of the worry, that the United States itself might use a nuclear weapon against the mountain. There is no credible reporting indicating that is the plan. Every account of the administration’s strategy centers on conventional munitions, specifically the enormous bunker buster bombs the American military has developed precisely because facilities like Fordow and now Pickaxe Mountain are too deep for ordinary weapons to reach. The Times of Israel detailed this equipment directly, explaining that underground facilities like this one led the United States to develop the GBU-57, a bomb capable of penetrating at least sixty meters, or roughly two hundred feet, of earth before detonating, according to the American military. Even that weapon may not be enough on its own. U.S. officials have reportedly discussed using two of these bombs in sequence to guarantee a facility is fully destroyed, and it remains unclear whether even that combination could reach a site as deep as Pickaxe Mountain. This is a story about the largest conventional bombs on earth straining at the absolute limits of their design, not a story about nuclear weapons being deployed against Iran. The Times of Israel The Times of Israel

The more layered and more interesting question is what happens if a conventional bomb, even one as massive as the GBU-57, actually strikes stored nuclear material like enriched uranium or a bank of centrifuges. This is where the popular imagination tends to run well ahead of the physics, and where the actual expert consensus is worth laying out carefully because it cuts against the more dramatic assumptions many people carry into this conversation. Nuclear physicist and journalist Geoff Brumfiel addressed this directly in comments to NPR during an earlier round of strikes on Iranian facilities, explaining plainly that even if a bunker buster succeeded in breaching a facility and rupturing stored material, it would not trigger a nuclear explosion, because the enriched uranium stored at sites like Fordow is kept in gas form, which cannot sustain the runaway nuclear chain reaction required for a nuclear detonation. That is a critical technical distinction. A nuclear weapon requires a specific engineered geometry, a precisely triggered implosion or gun-type assembly, and enough fissile material arranged in exactly the right way to go supercritical in a fraction of a second. Simply cracking open a storage container with a bomb does not replicate that process, no matter how large the explosion. NPR

That does not mean such a strike would be harmless, and it is worth being honest about the real risks rather than swinging from exaggerated fear to false reassurance. Emily Caffrey, a radiation health physicist at the University of Alabama at Birmingham, told NPR that people often misunderstand the nature of the danger, noting that uranium is actually more chemically toxic than it is radiologically toxic. That reframes the danger away from the popular image of a mushroom cloud or a Chernobyl style meltdown and toward something more mundane but still genuinely hazardous, toxic gas exposure and localized contamination for anyone near the immediate blast site. NPR

Other nuclear engineers have made similar points using stronger language specifically to push back on the Chernobyl comparison that circulates so often in public discussion. Simon Middleburgh, a professor of nuclear engineering at Bangor University’s Nuclear Futures Institute, told Time magazine that striking an enrichment site does not carry the same hazard as an accident at a functioning nuclear reactor, because enrichment itself does not involve fission, which is the process that creates the real peril in handling radioactive material. He added that any contamination from such a strike would most likely stay local rather than spreading regionally. That assessment was echoed by the world’s chief nuclear watchdog. Rafael Grossi, the director general of the International Atomic Energy Agency, stated after an earlier round of strikes on Iranian enrichment sites that no increase in off site radiation levels had been reported, and he specifically identified chemical toxicity, not radiological fallout, as the primary concern arising from those attacks.

Former nuclear officials interviewed by NBC News offered perhaps the most direct rebuttal to the fear driving so much of the current online conversation. Discussing the possibility of striking Iran’s Fordow facility with the same type of massive bomb being discussed for Pickaxe Mountain, these officials explained that while the force of such an explosion would likely cause casualties among anyone still inside the facility, it would not trigger a nuclear explosion or a widespread radiological or chemical spill. They were careful to note the conditions under which that calculus would change entirely, explaining that a dramatically different and far more dangerous outcome would only occur if the facility in question housed nuclear reactors or actual warheads, which international watchdogs and outside experts do not believe to be the case at these enrichment sites. A retired British military officer who once commanded his country’s chemical, biological, radiological and nuclear defense regiment put it even more starkly to NBC News, warning that anyone physically present underground during such a strike would face lethal consequences purely from the scale of a five and a half ton conventional warhead, while separately dismissing comparisons to a nuclear disaster, stating flatly that “blowing up uranium will not create a nuclear explosion.” NBC News + 2

So where does that leave the actual public interest question, because dismissing the most dramatic version of the fear is not the same thing as saying there is nothing to worry about here. There is plenty to worry about, just not necessarily the specific mechanism that has been circulating. A strike on a facility believed to house hundreds of kilograms of enriched material and active centrifuge equipment carries real localized risk of chemical exposure and contained radiological contamination for anyone in the immediate vicinity, workers, IRGC personnel, and possibly nearby communities depending on wind patterns and the actual scale of any breach. Grossi himself has previously warned that strikes on Iranian nuclear infrastructure cause a sharp degradation in nuclear safety and security even when they do not produce a public facing radiological release, and he has specifically flagged alpha particle exposure inside damaged facilities as a serious hazard for anyone who inhales or ingests contaminated material. None of that requires a nuclear detonation to be genuinely dangerous, environmentally damaging, and legally fraught under international frameworks governing attacks near nuclear material.

And that legal and diplomatic dimension may ultimately matter more than the physics. Regardless of whether a strike on Pickaxe Mountain produces anything resembling a nuclear explosion, the act of a nuclear armed state deliberately targeting a facility that houses, or is believed to house, nuclear material sets a precedent that the International Atomic Energy Agency and much of the international community have historically treated as a serious escalation in its own right. It normalizes military strikes against nuclear infrastructure as a tool of foreign policy, a precedent that could just as easily be invoked by other nuclear armed states against facilities elsewhere in the world, including ones far less carefully monitored than Iran’s. It also risks provoking Iran into responses that have nothing to do with the physics of uranium gas canisters and everything to do with wounded national pride, regional deterrence calculations, and a felt need to demonstrate resolve, potentially through strikes on shipping in the Strait of Hormuz, regional American assets, or allied nations, all of which carry their own cascading risks for global energy markets and regional stability that dwarf the immediate contamination footprint of the strike itself.

There is also the deeper strategic question hovering over all of this, one that outside experts have raised without fully resolving. If the actual goal is preventing Iran from ever assembling a nuclear weapon, does striking Pickaxe Mountain accomplish that, or does it simply push the program further underground, literally and figuratively, hardening Iranian resolve to build deeper, harder to reach facilities the next time around, the same pattern that produced Pickaxe Mountain itself after an earlier attack on Natanz years ago. Analysts have already noted the site was specifically designed and reinforced with additional overburden and concrete headworks precisely because Iran anticipated future strikes, a design philosophy that suggests military pressure alone may simply be teaching Tehran to build better bunkers rather than abandoning its ambitions altogether.

What is clear, cutting through both the exaggerated fears and the reassuring expert consensus alike, is that the United States appears genuinely prepared to strike one of the most fortified and ambiguous nuclear adjacent facilities on earth, in the middle of an already active and escalating war, based on intelligence that even the president himself describes as unconfirmed. Whatever the precise physics of what happens underground when that bomb lands, the political, diplomatic, and human consequences of that decision will be measured for years, not days, and they will not depend on whether uranium gas can achieve criticality in a ruptured canister. They will depend on how the rest of the world, and especially Iran itself, chooses to respond to watching America strike at the very heart of what it fears most.
