The media is currently panicking over a pile of granite in central Iran.
Every major outlet is running the same lazy, copy-pasted narrative. They tell you that Pickaxe Mountain—or Kūh-e Kolang Gaz Lā—is an impregnable underground nuclear fortress. They point to satellite images of dump trucks and concrete mixers. They quote hand-wringing defense analysts who warn that the site is buried up to 600 meters deep. They declare that because the U.S. military’s GBU-57 Massive Ordnance Penetrator only digs down about 60 meters, the facility is completely "untargetable".
Then Donald Trump gets on a radio show and boasts about blowing it up with a "nice big fat shot right in the front door," and the pundit class loses its mind. They scream that he is ignoring the physical laws of geology and military engineering.
Both sides are fundamentally wrong.
The defense establishment is blinded by a superficial obsession with depth. Trump, through sheer bombastic instinct, is actually closer to the tactical reality than the PhDs writing white papers.
I have spent years analyzing how states hide their most sensitive military and industrial infrastructure. If you want to understand the actual chess game being played in the Zagros Mountains right now, you have to stop looking at the top of the mountain and start looking at how a subterranean facility actually breathes.
The 600-Meter Depth Myth
Let's dismantle the central premise of the current consensus: the idea that depth equals absolute invulnerability.
Yes, the geology is impressive. Pickaxe Mountain is a massive granite ridge rising 1,608 meters above sea level. The underground halls are estimated to sit between 100 and 600 meters beneath solid rock. Granite has immense compressive strength. It is highly effective at absorbing and dispersing the kinetic energy and shockwaves of conventional bunker-buster bombs.
If your goal is to physically vaporize a centrifuge hall 300 meters beneath a granite shield using a conventional warhead dropped from a B-2 bomber, you cannot do it. That is a physical fact.
But physical destruction is a primitive way to think about military neutralization.
An underground nuclear facility is not a self-sustaining, closed biosphere. It is an open, highly sensitive mechanical system. To run a modern uranium enrichment facility, you do not just need a deep cave. You need:
- Continuous, ultra-stable electrical power: Thousands of centrifuges spinning at over 1,000 Hertz require a flawless, uninterruptible power supply. A millisecond of power fluctuation can cause a cascade of mechanical failures, destroying the delicate carbon-fiber rotors.
- Massive industrial cooling systems: Centrifuges generate immense heat. If you cannot reject that heat to the outside atmosphere, the entire underground hall quickly becomes an oven, warping the machinery and ruining the product.
- Ventilation and gas management: You need constant air exchange and highly specialized filtration systems to keep the air breathable and prevent chemical blockages.
- Ingress and egress routes: You need to move workers, heavy equipment, gas cylinders, and raw materials in and out of the mountain.
To maintain these inputs, a deeply buried facility must connect to the outside world. It does this through highly vulnerable, easily targetable external nodes: electrical substations, cooling towers, ventilation shafts, and tunnel portals.
If you crater the portals, collapse the access tunnels, and obliterate the external power grid, it does not matter if the centrifuge hall 300 meters below is pristine. You have converted a multi-billion-dollar nuclear facility into a dark, hot, silent tomb.
The mountain is not an impenetrable shield. It is a choke point.
Why Trump's "Front Door" Strategy is Tactically Sound
When Trump told Hugh Hewitt that Pickaxe is "a possible target for a nice big, fat shot right in the front door," the foreign policy establishment treated it as typical bluster. It was mocked as a simplistic solution to a complex engineering challenge.
It is actually the exact way military planners neutralize deeply buried targets.
In military doctrine, this is known as "functional defeat." You do not need to penetrate the rock; you target the portals and the headworks.
Satellite imagery from organizations like the Institute for Science and International Security shows that Iran is actively pouring concrete and reinforcing the Western and Eastern tunnel entrances of Pickaxe Mountain. They are adding massive concrete headworks and piling rock and soil over the portals.

Why are they doing this? Because they know the entrance is their glass jaw.
If a precision-guided munition, such as a GBU-57 or even smaller Joint Direct Attack Munitions (JDAMs), strikes the concrete headworks of a tunnel portal, the resulting landslide and structural collapse seals the entrance. The pressure wave traveling down the tunnel shaft can also destroy the blast doors and blow out the internal ventilation ducting.
You do not need to dig through 600 meters of granite. You just need to break the "front door." Once the portals are collapsed and the ventilation shafts are choked with rubble, the facility is useless. Re-excavating those tunnels under the threat of persistent, follow-on air strikes is an operational nightmare.
The critics arguing that Pickaxe Mountain is "untargetable" because of its depth are fighting the last war. They are thinking in terms of total annihilation rather than operational denial.
The Magician's Trick: The Material is Already Gone
The real danger of the current media obsession with Pickaxe Mountain is that it acts as a massive decoy.
Iran has spent decades playing a shell game with its nuclear assets. The mainstream media falls for it every single time. They hyper-focus on the most dramatic, highly visible construction projects while ignoring where the actual, dangerous material is located.
Consider what happened during the June 2025 war. The U.S. and Israel launched massive strikes against Fordow and Natanz. Satellite imagery confirmed severe damage to the surface structures and some underground assets. Trump triumphantly declared that Iran's nuclear sites were "obliterated."
Yet, intelligence reports later revealed a glaring truth: days before the strikes, Iran had quietly moved approximately 440 kilograms of 60% enriched uranium out of Fordow. Where did it go? It was reportedly transported to Isfahan, a site that was only hit with Tomahawk cruise missiles rather than earth-penetrating bunker-busters.
The material survived.
Now, we are seeing the exact same pattern repeat with Pickaxe Mountain.
Because Pickaxe Mountain is currently non-operational and still under construction, there is no active uranium enrichment happening inside its tunnels. The site is essentially a massive, highly fortified construction zone.
By threatening to blow up the mountain, the U.S. is focusing its military energy and domestic media attention on an empty concrete shell. Meanwhile, the highly mobile enriched uranium stockpiles, the advanced centrifuge components, and the key nuclear scientists are distributed across highly unremarkable, civilian-looking commercial warehouses and academic institutions throughout Iran.
If you want to stop Iran from building a nuclear weapon, bombing Pickaxe Mountain is a side show. The real threat is the material that isn't in the mountain.
The True Cost of the "Bomb the Mountain" Fantasy
To be clear, launching a military campaign to strike Pickaxe Mountain is not a risk-free endeavor, nor is it the clean, decisive victory that political leaders want to sell you.
While a functional defeat of the site is highly achievable through targeted strikes on its portals and external infrastructure, the strategic fallout of such an action is massive:
- The Sabotage of Verification: Striking a non-operational, undeclared facility completely destroys any remaining diplomatic leverage. It guarantees that Iran will permanently bar the International Atomic Energy Agency (IAEA) from ever inspecting its territory again, forcing Western intelligence to rely entirely on satellite imagery and human assets.
- Accelerating the Dash: Historically, military strikes do not eliminate a nation's nuclear ambitions; they supercharge them. If Iran’s leadership believes their underground facilities are subject to preemptive strikes regardless of treaties or negotiations, their logical move is to abandon all pretense of peaceful development, expel all monitors, and rush to build a small, highly mobile deterrent that can be hidden in deep, natural caves far away from known military targets.
- Global Supply Chain Shock: A strike on Pickaxe Mountain will not occur in a vacuum. It is inextricably linked to the ongoing, highly volatile maritime conflict in the Strait of Hormuz. The moment U.S. bombs hit the Zagros Mountains, the global energy market will face a massive disruption as the shipping lanes that carry nearly 20% of the world's oil are completely choked off by retaliatory strikes and defensive naval blockades.
Stop asking whether a bunker-buster can penetrate 600 meters of solid granite. That is the wrong question, asked by people who do not understand the mechanics of modern warfare.
The real question is whether the United States is willing to trigger a global economic shockwave to collapse some concrete tunnels and destroy a facility that does not even have uranium in it yet.
The mountain is a distraction. The real game is being played right out in the open.
