ANALYSIS: Post-strike Iran — what remains of Tehran's nuclear program

ANALYSIS: Post-strike Iran — what remains of Tehran's nuclear program

Introduction: one year after Operation Midnight Hammer, the ghosts persist

Strikes that changed the Middle East

In June 2025, the United States and Israel launched Operation Midnight Hammer — a strike campaign targeting Iran's principal nuclear facilities. Natanz and Fordow were hit. Satellite images showed craters, gutted buildings, infrastructure in ruins. The West exhaled. Tehran howled. And a year later, the fundamental question remains unanswered: what is the actual state of Iran's nuclear program?

According to reporting gathered by Fox News Digital on June 26, 2026, the agreement between Washington and Tehran now hinges — critically — on the International Atomic Energy Agency (IAEA) gaining access to Iranian nuclear sites. Access that Iran refuses or doles out drop by drop, exactly as it has done for twenty years.

The IAEA facing a familiar wall

History repeats with dispiriting precision. The IAEA wanted to inspect the damaged sites. Iran's foreign ministry denied having invited the inspectors. Iranian Deputy Minister Kazem Gharibabadi wrote on X that "there is no plan for access to the facilities that were attacked." Meanwhile, President Trump claimed on Truth Social that Iran had "fully and completely agreed to nuclear inspections at the highest level." Welcome to post-Midnight Hammer geopolitics: every actor tells its own story, and no one knows the truth.

What the strikes actually destroyed

Natanz and Fordow: the documented damage

The Institute for Science and International Security, analyzing post-strike IAEA reports, established that the above-ground pilot fuel enrichment plant at Natanz was destroyed. Other facilities sustained significant damage. The BBC reported as early as June 2025 that American officials stated the strikes had "considerably impaired" Iran's nuclear ambitions.

But the devil is in the details. The underground section of Fordow, buried tens of meters beneath bedrock, held. The precision centrifuges, the stored highly enriched uranium, the blueprints and the engineers — none of these were touched, or had already been relocated before the strikes. Hassan Abed, policy director of Iranian state television, said as much himself: the sites "had been evacuated in advance."

The enriched uranium: dispersed or destroyed?

The most crucial question, according to experts cited by Fox News Digital, concerns the highly enriched uranium stored in these facilities. Jason Brodsky, an Iran-focused analyst, insists: Tehran should "bare itself and allow inspections" not only at declared nuclear sites but also at universities, military bases, and state organizations used for dual-use research. Because if part of the enriched uranium stockpile was moved before the strikes, the program survived its own ruins.

David Albright, founder of the Institute for Science and International Security and a global reference on nonproliferation, is blunt in his assessment: Iran "likes to generate action plans that can be prolonged," and this entire process risks becoming "a sterile exercise." His warning is direct: "It is really important that the Trump administration does not redo a JCPOA" — meaning the type of soft agreement Iran signed in 2015 under Obama that carefully set aside the weapons question.

The Memorandum of Understanding: a text with blurry contours

Rafael Grossi caught between two fires

IAEA Director General Rafael Grossi finds himself in an uncomfortable position. On June 25, 2026, speaking from Tokyo, he declared that a Memorandum of Understanding (MOU) had been signed by Trump and President Pezeshkian and that the deal "expressly states that the nuclear part will be supervised and monitored by the IAEA." He added that "initial conversations" had begun on inspections and that the agency hopes to "be there soon."

But — and this is a colossal "but" — Grossi himself declined to confirm whether his team would examine all Iranian nuclear weapons sites and all suspected sites. The IAEA refused to answer Fox News Digital's questions about why previous monitoring efforts had failed, what would be different this time, and whether inspectors would have access to meaningful or merely symbolic sites.

The G7 and diplomatic pressure

In their final communiqué from the June 2026 G7 summit at Évian, heads of state declared they were "ready to contribute to the implementation" of the agreement and stressed the need for robust follow-on negotiations. They reaffirmed that "Iran will never obtain a nuclear weapon." Words. Fine words. But G7 statements are not verification mechanisms.

U.S. Vice President JD Vance presented the invitation of IAEA inspectors as "a major step" and the first move toward permanent denuclearization. But inviting inspectors and giving them access to what matters are two very different things. Iran is expert at that distinction.

The ten sites and beyond: what the IAEA may never see

"Pickaxe Mountain" and buried secrets

According to David Albright, the Israeli government has identified "ten or more sites" where Iran is suspected of activities related to nuclear weapons. Among them, a site known as "Pickaxe Mountain", described as particularly strategic — and which was not targeted during Operation Midnight Hammer. The IAEA declined to confirm whether its inspectors would demand access to it.

That is where the core problem lies. IAEA inspections of the damaged sites would document the destruction and attest to its reality — useful for political communication. But what matters for effective nonproliferation is access to the undamaged sites where the program may have been relocated, to the universities training nuclear engineers, and to the military bases possibly housing critical components.

NPT obligations violated

Jason Brodsky is categorical: Iran's refusal to permit inspections at the damaged facilities since June 2025 constitutes a violation of its obligations under the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). This is not a contested interpretation — it is a direct reading of the text. An NPT state party that sustains military action against its declared facilities is obligated to cooperate with the IAEA to establish the situation.

Iran has violated that obligation for twelve months. And American negotiators, pressed by the logic of the deal, chose not to make this a dealbreaker. This is precisely what Albright denounces when he says the Obama 2015 deal had "swept this under the rug."

What Iran preserved, dispersed, or rebuilt

The resilience of a decentralized program

One often underestimated aspect of Iran's nuclear program is its progressive decentralization since at least 2010. As strike threats accumulated, Tehran developed a strategy of dispersing critical capabilities. Engineers were relocated. Plans were duplicated. Essential components were stockpiled in undeclared sites. This structural resilience means that even successful strikes on known facilities do not destroy the entire program.

Armed Forces News analysis on the post-strike state of the program indicates that while surface facilities sustained significant damage, the human expertise — engineers, scientists, centrifuge specialists — was not eliminated. A nuclear program is, above all, minds. And Iran's nuclear minds are still there.

The breakout timeline question

Before the 2025 strikes, analysts estimated Iran had reduced its "breakout timeline" — the time needed to produce enough highly enriched uranium for a bomb — to less than one month. The damage to centrifuges and enrichment infrastructure has extended that timeline. But by how much? Estimates range between six months and two years, depending on the analyst and on how much enriched uranium Iran managed to shelter before the strikes.

The IAEA is the only organization with the legitimacy and technical tools to answer this question. But it can only do so if it has access to the relevant sites. And that access is precisely what Iran is negotiating, delaying, and conditioning. Every month of delay is a month the program can use to reconstitute itself.

The American deal: a "peace" or a pause?

The MOU and its structural flaws

The Memorandum of Understanding signed between Washington and Tehran is presented as a historic turning point. Trump sells it as an absolute victory. Vance speaks of a "first step toward permanent denuclearization." But experts raise fundamental questions about what the MOU actually contains. Are IAEA inspections clearly defined? What timeline? What penalties for non-compliance? Which sites are covered?

The silence of the U.S. State Department on these questions — it "declined to comment" on Fox News Digital's requests — is not reassuring. An agreement whose terms cannot be discussed publicly is not a transparency agreement. It is an image-management agreement.

A JCPOA 2.0 — at the risk of repeating JCPOA's errors

David Albright delivered his most direct warning: "it is really important that the Trump administration does not do a JCPOA." The Obama 2015 deal had deliberately sidestepped the weapons question — focusing on civilian enrichment while leaving the military dimension of the program in a blind spot. Iran signed, cooperated on the visible aspects, and continued working on the concealed ones.

If the new deal reproduces this structure — Iran accepting inspections at damaged sites in exchange for sanctions relief, while protecting its sensitive military sites — the West will have purchased an appearance of peace with a nuclear threat gestating in the shadows. Brodsky insists: "any new deal should include more robust inspection powers" than those in the JCPOA. History tells us that is also what Iran will resist most obstinately.

The West's allies facing the Iranian file

Israel: between preemptive strike and diplomatic calculus

For Israel, the Iranian nuclear question is not abstract. It is existential. The Netanyahu government participated in the Midnight Hammer Operation of June 2025 — contributing its air power to a Washington-led coalition. A year later, Tel Aviv watches the American-Iranian negotiations with barely concealed anxiety. The Obama-JCPOA deal of 2015 had been rejected by Israel precisely because it did not cover the military dimensions of the program. A sequel that reproduced the same gap would be seen by Israel as strategic betrayal.

Israeli leaders demand an absolute guarantee: zero tolerance for an Iran with nuclear breakout capacity. The prime minister reaffirmed this line during his talks with the American delegation in Tokyo. If the deal does not provide unconditional inspections and an automatic sanctions trigger in case of violation, Israel will reserve the right to unilateral action. This is a pressure Trump must manage even as he negotiates with Tehran.

Europe and the sanctions dilemma

The European Union — France, Germany, United Kingdom, the so-called E3 — spent years maintaining the JCPOA diplomatic framework, even after the American withdrawal in 2018. These three powers have a voice in current negotiations, and they insist on a multilateral approach. For Europeans, a bilateral U.S.-Iranian agreement without robust IAEA verification would be a dangerous precedent — signaling to other aspiring nuclear powers that resistance to international pressure ultimately pays off.

The June 2026 G7 summit communiqué was clear: "a non-nuclear Iran is indispensable to regional security." But G7 declarations have never stopped an enrichment program. What might stop it is a deal with verifiable guarantees — precisely what Iran refuses to provide on its military sites. The circle remains as vicious as it was before the strikes.

Scenarios for the coming months

Optimistic scenario: inspections arrive

In the best-case scenario, the IAEA gains access in the coming weeks to the damaged sites and related military sites. Grossi can finally assess the true scope of the destruction and what remains. Precise technical data allows the ongoing agreement to be calibrated. Discussions advance on a permanent inspection framework, more robust than the JCPOA's, explicitly covering the military dimensions. A preliminary agreement is signed in autumn 2026 with a progressive sanctions-relief schedule conditioned on verifiable milestones.

This scenario is possible. It is far from probable. It requires Iran to agree to show what it has hidden — a concession that runs counter to the regime's survival logic. But if sanctions and economic isolation continue to exert sufficient pressure, and if Tehran concludes that a deal is better than continued accelerating impoverishment, the window exists.

Pessimistic scenario: the deal without verification

In the pessimistic scenario, Iran maintains its refusal to allow inspections at military sites. Trump, eager to display a "deal" before the midterm elections, accepts an agreement on civilian sites while leaving military sites in the dark. The world gets images of good intentions and peace communiqués — without the data to assess whether the nuclear threat is actually contained. Sanctions are progressively lifted. Iran cashes in the economic benefits while maintaining carefully cultivated strategic ambiguity.

This scenario is, according to all experts cited in this article, the most probable if current dynamics persist. Brodsky and Albright are not hawks dreaming of bombing runs — they are analysts who have studied the Iranian file for decades. When they say the deal risks reproducing the JCPOA's errors, they say it on the basis of available evidence. This would be the repetition of a historical mistake we have already paid for.

Conclusion: verify or believe?

Reagan's maxim in the post-Midnight Hammer era

"Trust, but verify." Ronald Reagan's famous maxim during nuclear negotiations with the USSR has never been more relevant than it is today facing Iran. Except that in this precise case, verification is exactly what Tehran refuses to provide. The MOU speaks of inspections. Iran says there is no plan for the damaged sites. Grossi says he hopes to "be there soon."

A year after historic strikes, the world still does not know what Iran has preserved of its nuclear program. It does not know how long it would take Tehran to produce a bomb if the regime so decided. This ignorance is unacceptable. And no declaration in Tokyo, no Truth Social post, can remedy it. Only real, complete, unconditional inspections — at all relevant sites — can answer the question.

The test to come

According to David Albright, the way Iran treats the IAEA in the coming weeks "will tell whether the negotiations are meaningful." That is the only test that counts. Not press releases. Not presidential speeches. Not G7 resolutions. If IAEA inspectors freely access the critical sites, the negotiations deserve to be taken seriously. Otherwise, we are watching yet another replay of a play we already know — and whose ending we already know.

Who I am and my acknowledged biases

I am Maxime Marquette, columnist and analyst. I am not a nonproliferation specialist — I rely on recognized experts such as David Albright and Jason Brodsky. My bias: I regard a nuclear-armed Iran as an existential threat to Israel, to regional stability, and to the international order. I believe diplomacy is preferable to war, but not at any price.

What I do not know and my method

I do not know the precise contents of the U.S.-Iranian Memorandum of Understanding — the details have not been disclosed. I do not know the exact current state of Iran's nuclear facilities. My analyses rely on sources from June 25–26, 2026: Fox News Digital, BBC, Armed Forces News, G7 declarations, and independent expert analysis. I flag my editorial opinions clearly.
