The Pentagon is planning to dig uranium out of a mountain. The real question is whether the uranium that matters most already left in somebody’s trunk.
On April 1, 2026, the Washington Post reported that the United States military has briefed President Trump on a plan to insert ground forces into Iran to physically remove approximately 970 pounds of highly enriched uranium from underground storage. The plan involves flying in excavation equipment, building a runway for cargo planes, and breaching tunnel complexes buried hundreds of feet inside granite mountains. Former commanders have estimated the operation could take weeks to months, require hundreds or thousands of troops, and constitute one of the largest special operations missions in history. The operational risks are enormous. The logistical demands are staggering. And the entire plan is built on an assumption that may already be wrong: that the uranium is still where the United States believes it to be.
The Kingpin Fallacy, Applied
Since 2007, Israel has systematically assassinated Iran’s senior nuclear scientists. Five were killed between 2010 and 2020 by motorcycle-mounted operatives using magnetic bombs and drive-by shootings. In November 2020, Mohsen Fakhrizadeh—regarded by Western intelligence as the architect of Iran’s nuclear weapons program—was killed by a remote-operated machine gun smuggled into Iran in pieces by the Mossad. Then, on June 13, 2025, in the opening hours of what would become the twelve-day war, Israel eliminated ten nuclear scientists simultaneously in Operation Narnia—all killed in their beds, targeted at the same moment so none could be warned. At least sixteen senior nuclear scientists have been eliminated in fifteen years.
The strategic logic was the same logic that has driven American and Israeli targeting doctrine for decades: remove the irreplaceable individual, and the program collapses. It is the logic I described in “The Kingpin Fallacy,” published in CRUCIBEL in March 2026—the fifty-year pattern of killing leaders who are architecturally designed to be replaced. The pattern holds in narcotics networks. It holds in terrorist organizations. And the evidence suggests it holds in nuclear programs.
After the earlier assassination campaign, Ali Akbar Salehi, the head of Iran’s Atomic Energy Organization, told Science magazine that the killings did not impede Iran’s nuclear activities. The opposite occurred: students in other fields switched to nuclear science. Iran built what Salehi called “an efficient system” capable of continuing without any single individual. The assassinations did not create a vacuum. They created a generation of replacements who were younger, angrier, and motivated by something more durable than institutional loyalty. They were motivated by martyrdom.
The Orphan’s Access
This is where the assassination campaign intersects with a problem that no one in Washington appears to be discussing publicly. Iran’s nuclear program employed thousands of scientists, engineers, and technicians across multiple facilities. The enriched uranium—stored as uranium hexafluoride gas in sealed cylinders roughly the size of scuba tanks—was handled, transported, and catalogued by these personnel. IAEA Director General Rafael Grossi has described the cylinders as “not very big” and “not specially protected.” A single person can move one. A pickup truck can carry several.
The senior scientists who were killed—the Fakhrizadehs, the Tehranchihs, the Abbasis—were institutional men. They operated within command structures. They answered to the supreme leader. They had careers, families, reputations, and institutional positions that made them fundamentally deterrable. The people who replaced them are not the same. They are the graduate students who watched their professors get blown apart. They are the mid-career researchers who have seen their life’s work bombed three times in ten months. They are the ones who switched into nuclear science specifically because their mentors were assassinated. These are not people constrained by the same institutional calculus that governed their predecessors.
And those predecessors’ institutional anchor is gone. Ayatollah Khamenei was killed in a joint US-Israeli strike on February 28, 2026. The fatwa against nuclear weapons—whatever its true constraining force—died with him. The command structure that once governed what happened inside those mountains is fractured. The question is not whether Iran’s surviving nuclear personnel have the motivation to divert material. The question is what institutional mechanism remains to prevent them from doing so.
Ten Months of Darkness
The International Atomic Energy Agency—the sole international body with the mandate and the technical capability to verify the location and status of Iran’s enriched uranium—has been locked out since June 13, 2025. The IAEA has had no access to any of Iran’s four declared enrichment facilities for ten months. It cannot verify the size, location, or status of the stockpile. The cameras are off. The seals are broken. The inspectors are in Vienna.
Before the war, the IAEA estimated Iran possessed 440.9 kilograms of uranium enriched to 60 percent—enough, if further enriched, for the fissile cores of approximately ten nuclear weapons. Over 200 kilograms was stored in the underground tunnel complex at Isfahan, with the remainder at Natanz and possibly Fordow. Grossi has said he believes the material is “probably still there.” But “probably” is not verification. And the IAEA itself has acknowledged that even the Iranians reportedly have not been able to fully reenter the Isfahan facility since the strikes. Whether that remains true today is unknown. Whether it was true before the strikes—in the ten-day window between the Israeli attack on June 13 and the American strikes on June 22—is an even more critical question.
The Pentagon is solving the wrong problem.
On June 20, 2025, the former commander of Iran’s Revolutionary Guard publicly stated that enriched nuclear material had been moved to secure locations. The U.S. Defense Secretary said afterward that no intelligence suggested anything had been moved. One of those statements is wrong. Ten months later, neither has been resolved, because no one with the authority to verify is allowed inside.
And the intelligence picture is worse than silence. The E3 nations warned in March 2026 that the IAEA reports “increasing risk of diversion”. Sources in Tehran reported that in October 2025, Khamenei authorized the development of miniaturized nuclear warheads. Circulated accounts indicate the existence of an ultra-secret enrichment program at a covert nuclear site the IAEA has never accessed. On March 3, 2026—three days after Khamenei’s assassination—Iran’s Institute of Geophysics reported a 4.3-magnitude seismic event near Fin, in Hormozgan Province, at a depth of 22 kilometers. The USGS did not register any event at that location. No one has publicly explained the discrepancy.
The Cylinder
The entire Washington policy debate about Iran’s uranium is framed around state-level action: whether the Iranian government will agree to surrender the material through negotiation, or whether the United States will seize it by force. Both scenarios assume centralized control—that the material is where a government put it, guarded by forces a government commands, and accessible only through decisions a government makes.
A dirty bomb does not require any of those assumptions.
A radiological dispersal device is not a nuclear weapon. It does not require enrichment cascades, implosion lens design, weapons physics, or missile delivery systems. It requires conventional explosives and radioactive material. Foreign Policy reported in July 2025 that there was “little doubt” Iran has sufficient nuclear material to construct such a device. A dirty bomb using 60 percent enriched UF6 could render portions of a city, a port, or a military installation uninhabitable. It could be delivered by truck, by drone, by cargo ship, or by small aircraft. It does not require a launch code, a chain of command, or a national decision.
It requires one cylinder, one motivated person, and one vehicle.
And what the assassination campaign produced—what fifteen years of killing senior scientists and ten months of bombing created—is a population of motivated people with precisely the knowledge and access required. They know where the cylinders are because they put them there. They know the tunnel layouts because they worked inside them. They know how to handle uranium hexafluoride because it was their profession. And they are operating in an environment with no institutional oversight, no international monitoring, a dead supreme leader, and a country that has been under continuous bombardment for over a month.
The Truck Route Nobody Mentions
There is a further irony embedded in the Pentagon’s extraction plan. The Washington Post describes an operation that involves building a runway, flying in excavation equipment, and digging down through hundreds of feet of mountain from above. But the uranium did not enter the mountain from above. Satellite imagery from June 9, 2025, captured a flatbed truck carrying 18 blue barrels toward the southern tunnel entrance of the Isfahan underground complex, followed by a truck-mounted crane and security vehicles. The material was driven in on a road, through a horizontal tunnel entrance, and stored inside. The same road exists for driving it out.
The tunnel entrances were bombed and backfilled. But the backfill is dirt, not granite. Iran itself cleared two of three entrances within months using dump trucks and construction equipment, and by November 2025 had installed protective barriers at the reopened northern entrance. If Iran’s own engineers could reopen these tunnels with basic heavy equipment, the question of how long it would take a determined insider to access the material through a partially cleared entrance is different from the question of how long it would take a commando force to bore through solid mountain from above.
The Pentagon is solving the wrong problem. The commando plan addresses external seizure of a stockpile assumed to be intact and centrally controlled. The threat this analysis identifies is internal diversion from a stockpile that has been unmonitored for ten months, in a country whose nuclear personnel have been systematically radicalized by assassination and bombardment, under a command structure that no longer exists in its pre-war form.
What the Evidence Does Not Prove
Intellectual honesty requires naming the limits of this analysis. The evidence does not prove that any material has been diverted. It does not prove that any individual scientist or technician has acted or intends to act outside institutional authority. It does not prove that Iran’s internal security apparatus—degraded as it is—has lost the ability to prevent unauthorized access to nuclear material. The IAEA’s assessment that the material is “probably” in the same locations is based on satellite observation of the facilities and represents the best available open-source judgment.
But “probably” is doing extraordinary work in that sentence. It is carrying the weight of ten months without physical verification, a decapitated leadership, an active war, a known ten-day diversion window at the war’s outset, satellite imagery that can see vehicles but not cylinders, and a country with every reason to conceal the true status of its most strategically consequential asset. The purpose of this analysis is not to assert that diversion has occurred. It is to identify the structural conditions under which diversion becomes possible—and to observe that every one of those conditions currently exists.
The Orphan’s Inheritance
The Kingpin Fallacy holds that killing leaders does not eliminate the organizations they lead. It distributes the capability, decentralizes the decision-making, and radicalizes the successors. Applied to Iran’s nuclear program, the pattern is precise. Sixteen senior scientists eliminated. Thousands of junior scientists and technicians remaining. A stockpile sufficient for ten nuclear weapons, stored in portable cylinders, inside tunnels that were accessed by truck. Ten months of zero international monitoring. A supreme leader assassinated. A fatwa dissolved. And a generation of nuclear professionals whose formative experience is watching their mentors get killed and their facilities get bombed.
The Pentagon is planning the largest special operations mission in history to dig uranium out of a mountain. The question no one is asking publicly is whether the material that matters most—a single cylinder, enough for a dirty bomb that could contaminate a city—already left the mountain in somebody’s trunk. Not on the orders of a government. Not as an act of state policy. But as the act of an orphan who inherited the keys to the kingdom and decided the kingdom owed him something back.
The mountain keeps what it was given. Unless someone who knows the mountain decides otherwise. And fifteen years of assassination ensured that the people who know the mountain best are the ones with the least reason to protect what’s inside it.
