The Mossad's Intelligence Failure Left Iran More Dangerous Than Before

On February 11, 2026, Benjamin Netanyahu stood in the White House Situation Room and sold Donald Trump a war.

He came with a video montage, with intelligence assessments, with Mossad director David Barnea on a screen promising what no intelligence chief should ever promise: certainty. Iran's ballistic missile program could be destroyed in weeks. Tehran would be too weakened to close the Strait of Hormuz. Protests would erupt in the streets. The regime, Barnea told the assembled Americans, could be galvanized into collapse. There was even a slide deck about who would replace the mullahs, complete with names, including Reza Pahlavi, son of the last Shah, waiting in the wings of Washington think tanks for his restoration.

Trump, who wanted a quick and dramatic win, believed them.

And why wouldn't he?

The chairman of the Joint Chiefs warned repeatedly that securing the Strait would be extremely difficult. U.S. military planners told Trump that Iranians would not take to the streets while bombs were falling. American intelligence officials assessed the chances of a mass uprising as low. A classified National Intelligence Council report concluded that even a large-scale assault was unlikely to topple the regime. Iran's own intelligence apparatus, its IRGC, its Basij, its Revolutionary institutions, had spent four decades building precisely the kind of internal security architecture that exists to survive exactly this kind of external assault.

None of it mattered. The dissenters were sidelined. The war was launched.

What followed was not regime change. It was something far more dangerous.

Khamenei was killed on February 28, the first day of strikes. His death, which Israeli planners had apparently assumed would trigger the fall of the Islamic Republic, instead triggered the opposite. Iranians who despised the regime, who would under different circumstances have been in the streets, stayed home. Not because they loved the mullahs but because nobody takes to the streets against a government while a foreign air force is bombing their country. That is not a subtle point. It is, in fact, one of the most well-documented phenomena in the history of modern warfare. External attack consolidates regime legitimacy. It has done so from Serbia to Iraq to Libya. It did so in Iran in 2026.

"A lot of protesters are not coming into the street because they'll get shot," a senior U.S. official told the New York Times. "They're going to get slaughtered. That's one thing. But the second thing is that there's a good chunk of people who just want a better life, and they're sidelined right now. That 60 percent is going to stay home."

By mid-March, senior Israeli officials were quietly acknowledging to reporters what U.S. intelligence had been saying for weeks: the regime was not collapsing. The IRGC had consolidated power. A new supreme leader, Mojtaba Khamenei, younger and by multiple accounts more hardline than his father, had been installed. The old Khamenei had issued a fatwa against nuclear weapons and privately pushed back against military commanders who wanted the bomb. The new one carries no such constraint.

And here is the catastrophe that no one wants to say plainly: the war that was supposed to end the Iranian nuclear threat may have done the precise opposite.

Before the strikes, Iran's internal debate over the bomb was genuinely contested. Reformists argued for negotiation. Hardliners pushed for the weapon. The attacks settled that debate, and not in the direction Israel intended. Since February, prominent voices within the Iranian regime have openly demanded withdrawal from the Nuclear Non-Proliferation Treaty. The IRGC-affiliated Tasnim News Agency published that Iran should quit the NPT immediately. Conservative MP Mohammad Javad Larijani called for its suspension. State television aired a segment in which a commentator declared flatly: "After this war, Iran will be recognized as a global superpower. We must take measures to produce or possess nuclear weapons."

The IRGC is now dominant in a way it was not before. It is "consolidating power and reappointing hardline retired commanders to lead a younger, more vengeful generation of fighters," CNN reported in March. A new supreme leader who is harder, angrier, and unbound by his father's religious prohibitions is now in charge of the most consequential nuclear decision on earth.

This is what the intelligence failure produced.

And make no mistake: it was a failure. Not the spectacular sudden kind, like October 7, though the pattern of Israeli intelligence overconfidence that produced October 7 runs directly through this catastrophe. The former IDF intelligence chief who oversaw the October 7 failure said afterward that the core problem was "a belief that intelligence was omnipotent. It is not just arrogance, it's deeper." He was right. That arrogance did not die with October 7. It was exported to Washington, packaged in a video montage, and presented to a credulous president who wanted a win.

The war that was sold to Trump as a four-day regime change operation became a three-month grinding conflict that ended not in the fall of the Islamic Republic but in an American diplomatic surrender, a $300 billion reconstruction payment, $24 billion in unfrozen assets, and a nuclear framework that defers the hardest questions to 60 days of future negotiations with an Iran that is now more radicalized, more IRGC-controlled, more convinced of its own victimhood, and more motivated to acquire a nuclear deterrent than at any point in its history.

Chatham House put it with clinical precision: "Dialogue did not protect Iran." Every state watching this sequence reach that conclusion is drawing the obvious lesson. If negotiating with Washington while holding no nuclear weapon led to being bombed, the rational response is to acquire the weapon. Saudi Arabia's crown prince has already said repeatedly he will seek a bomb if Iran does. The proliferation cascade that the entire enterprise was meant to prevent may now be more likely than before a single bomb was dropped.

Israel went into this believing it could use American firepower to solve its Iranian problem once and for all. What it got instead is an Iran that is angrier, harder, more unified in its hatred, more IRGC-dominated, and more motivated for the bomb than at any point since 1979, sitting across a negotiating table from an American president who is already signaling he might accept enrichment continuing for 15 years.

The Mossad promised regime change in four days.

What the world got was a hardened theocracy, a $300 billion bill, a deferred nuclear file, and an Islamic Republic that its own military is publicly declaring won the war.

The intelligence was wrong. The war was launched anyway. And the people who will live with the consequences are not sitting in the Situation Room.
