JERUSALEM – Israel left Iran shocked and weakened last week after executing a meticulously planned intelligence and military mission that targeted significant assets with remarkable accuracy.
Under the guidance of espionage and advanced AI technology, the Israeli military executed a nighttime assault using warplanes and armed drones, which had been covertly infiltrated into Iran. This action quickly neutralized critical enemy air defenses and missile positions, providing Israel with greater access to strike numerous nuclear facilities effectively and eliminate key generals and scientists. By the time Iran organized a counterattack, its capacity for retaliation — already compromised by earlier Israeli interventions — was severely reduced.
This narrative is drawn from discussions with 10 existing and past Israeli intelligence and military personnel, several of whom requested anonymity to discuss secretive activities.
It was not possible to independently verify some of their claims. But the former head of research at Israel’s spy agency, the Mossad, confirmed the basic contours of the attack, saying she had inside knowledge of how it was planned and executed.
“This attack is the culmination of years of work by the Mossad to target Iran’s nuclear program,” said Sima Shine, the former Mossad research director who is now an analyst at the Institute for National Security Studies.
Israel’s element of surprise was enhanced by Iranian officials’ apparent assumption that Israel wouldn’t attack while talks over its rapidly advancing nuclear program were ongoing with the U.S.
A sixth round of talks had been planned for last Sunday in Oman, but Israeli Prime Minister Benjamin Netanyahu activated “Operation Rising Lion” on Friday – after his country first notified President Donald Trump.
Netanyahu has for years said neutralizing Iran’s nuclear program was vital for Israel’s security, and Israel had previously taken steps to set back Iran’s ability to enrich uranium to weapons grade. But Netanyahu said a more aggressive attack proved necessary, as Iran kept advancing its enrichment program despite U.S. diplomatic efforts and warnings from U.N. watchdogs.
Iranian Supreme Leader Ayatollah Ali Khameini has repeatedly called for Israel’s destruction. Iran’s political leaders say their nuclear program is for peaceful purposes, though it was the only country without the bomb to enrich uranium close to weapons-grade levels.
Smuggling drones into Iran
The Mossad and the military worked together for at least three years to lay the operational groundwork, according to a former intelligence officer who said he had knowledge of the attack. This person spoke on condition of anonymity given the sensitivity of the subject.
The attack built off knowledge Israel gained during a wave of airstrikes last October, which “highlighted the weakness of Iranian air defenses,” said Naysan Rafati, an Iran analyst at the International Crisis Group.
To further diminish Iranian air defenses and missile systems at the start of last week’s attack, Mossad agents had smuggled precision weapons into Iran that were prepositioned to strike from close range, according to two current security officials who spoke on condition of anonymity to discuss the missions. Those weapons included small, armed drones, which agents snuck into the country in vehicles, according to the former intelligence officer.
Mossad agents stationed weapons close to Iranian surface-to-air missile sites, Shine said. The agency works with a mix of people, both locals and Israelis, she said.
Using AI and human intelligence to select targets
To analyze information gathered from various sources, Israel used the latest artificial-intelligence, or AI, technology, said an intelligence officer involved with selecting individuals and sites to target. He said AI was used to help Israelis quickly sift through troves of data they had obtained. That effort began last October according to the officer, who spoke on condition of anonymity because he was not authorized to talk to the media; it was one month before Netanyahu said he had ordered the attack plans.
An investigation by The Associated Press earlier this year uncovered that the Israeli military uses U.S.-made AI models in war to sift through intelligence and intercept communications to learn the movements of its enemies. It’s been used in the wars with Hamas in Gaza and with Hezbollah in Lebanon.
The intelligence officer involved in identifying the possible targets said options were first put into various groups, such as leadership, military, civilian and infrastructure. Targets were chosen if they were determined to be a threat to Israel, such as being deeply associated with Iran’s Revolutionary Guard — a paramilitary force that controls Iran’s ballistic missiles.
The officer was tasked with putting together a list of Iranian generals, including details on where they worked and spent their free time.
Among the high-level military officials killed since Friday’s attack were Gen. Hossein Salami, the head of Iran’s Revolutionary Guard, and Gen. Mohammed Bagheri, the chief of staff of Iran’s armed forces.
In addition to AI, the Mossad relied on spies to identify top nuclear scientists and members of Iran’s Revolutionary Guard, according to one security official. At least eight members of the Guard, including the head of its missile program, were killed in a single Israeli strike on an underground bunker.
Targeting Iranian vehicles
Another facet of the attack was to strike Iranian vehicles used to transport and launch missiles.
Shine said the strategy was similar to a Ukrainian operation earlier this month in Russia. In that operation, nearly a third of Moscow’s strategic bomber fleet was destroyed or damaged with cheaply made drones snuck into Russian territory, according to Ukrainian officials.
In an interview with Iranian state-run television, the country’s police chief, Gen. Ahmadreza Radan, said “several vehicles carrying mini-drones and some tactical drones have been discovered.” He added: “a number of traitors are trying to engage the country’s air defense by flying some mini-drones.”
How far back does this go?
The Mossad is believed to have carried out numerous covert attacks on the Iranian nuclear program over the years, including cyberattacks and the killing of Iranian nuclear scientists. But it rarely acknowledges such operations.
In the 2000s, Iranian centrifuges used for enriching uranium were destroyed by the so-called Stuxnet computer virus, believed to be an Israeli and American creation.
In 2018, Israel stole an archive of Iranian nuclear research that included tens of thousands of pages of records, said Yossi Kuperwasser, a retired general and former military intelligence researcher who now directs the Jerusalem Institute for Strategy and Security.
In July 2024, Israel killed a senior leader of Hamas, Ismail Haniyeh, with a bomb in a bedroom of a government guesthouse in Tehran.
Israel’s blistering attack last week on the heart of Iran’s nuclear and military structure didn’t come out of nowhere, said retired Israeli Brig. Gen. Amir Avivi, who heads the Israel Defense and Security Forum think tank.
It was the result of “Israeli intelligence working extensively for years in Iran and establishing a very strong robust presence,” he said.
