From “Lifestyle” to Precision Strike: The Covert Mobilization of Israel and the United States to Kill Khamenei

For years, Israeli intelligence has been quietly tracking the movements of the most powerful man in Iran – Ayatollah Ali Khamenei.Now, in one of the most dramatic military operations in modern history, Iran’s supreme leader for more than three decades has been killed in coordinated US-Israeli strikes.

The mission was ambitious, long in the making, and, according to the Financial Times, built on years of patient observation, data collection, and political calculations.

When bodyguards and drivers for top Iranian officials arrived for work near Tehran’s Pasteur Avenue, the area where Khamenei was killed in an Israeli airstrike on Saturday, they likely had no idea they were being monitored.According to a report by the Financial Times, almost all traffic cameras in Tehran have been hacked for years.

Their feeds were allegedly encrypted and moved to servers in Tel Aviv and southern Israel, according to people familiar with the matter.One camera angle proved particularly valuable. It showed where security personnel parked their personal vehicles and provided an insight into the daily routine inside the heavily guarded complex.Over time, complex algorithms built detailed profiles, or what intelligence officers call “lifestyle.”

These files included home addresses, working hours, transportation routes, and most importantly, the officials each guard was assigned to protect.This was just one stream of intelligence. There were hundreds more.

Cut off communications before the strike

Israeli and US intelligence reportedly hacked mobile phone networks near Avenue Pasteur. At key moments, some phone towers went down, making the devices appear busy and preventing security teams from receiving potential warnings.Long before the bombs were dropped, Israeli intelligence had developed what one official described as an almost complete knowledge of Tehran.

“And when you know [a place] The Israeli intelligence official added: “As long as you know the street you grew up on, you notice one thing that is out of place.”This intelligence dominance was the result of years of work by Israeli Signals Intelligence Unit 8200, human sources recruited by Mossad, and extensive data analysis by military intelligence teams.Israel also used social network analysis, a mathematical method that studies relationships and patterns of influence, to examine billions of data points and identify new targets.“In Israeli intelligence culture, targeting intelligence is the most important tactical issue – it is designed to enable strategy,” said Itai Shapira, a brigadier general in the Israeli military reserves and a 25-year veteran of the Intelligence Directorate.

“If a decision-maker decides that someone should be assassinated, the culture in Israel is: ‘We will provide targeting intelligence.’”

A political decision, not just a military one

Even with this technological development, officials say that killing Khamenei was ultimately a political choice.

For years, Israel avoided targeting him directly. During the 12-day war last June, Israeli strikes killed more than a dozen Iranian nuclear scientists and senior military officials and disabled air defense systems.

But Khamenei was not attacked.This time was different.When American and Israeli intelligence decided that Khamenei would hold a meeting on Saturday morning at his compound, they saw a rare opportunity. Senior Iranian officials will meet in one place. If the war officially begins, they will likely move to underground bunkers beyond Israel’s reach.One person familiar with the situation told the Financial Times: “It was unusual for him not to be in his bunker – he had two bunkers – and if he had been, Israel would not have been able to reach him with the bombs they had.”Unlike his ally Hassan Nasrallah, who spent years hiding underground before being killed in Beirut in 2024, Khamenei did not live in constant hiding. He has spoken publicly about the possibility of being killed, and reportedly believed martyrdom was possible.

However, hitting him in broad daylight was a calculated move. The Israeli military later said the morning attack allowed for a tactical surprise, despite Iran’s preparedness.

The American role

Behind the scenes, Washington played a decisive role.While Israel obtained intelligence signals from cameras and hacked mobile phone networks, the Americans reportedly had a human source who confirmed that the meeting was going as planned. The CIA declined to comment.Israeli doctrine requires two senior officers working independently to confirm the target’s presence before a strike. For a high-ranking figure like Khamenei, failure was not an option.Israeli aircraft reportedly flew for hours before launching up to 30 precision-guided munitions. Some of the missiles used were variants of the Sparrow system, capable of hitting a target as small as a dining table from a distance of more than 1,000 kilometres.

How Trump moved toward war

The decision to escalate was not taken overnight.In early February, Israeli Prime Minister Benjamin Netanyahu met with US President Donald Trump in the Oval Office. For weeks, the two sides discussed potential military action against Iran, even as US officials were publicly engaged in nuclear negotiations with Tehran.

Trump expressed his frustration with diplomacy.He denied the history of talks with Iran, describing them as years “Talk, talk, talk.”In response to a question about whether he supports regime change, Trump said so “It seems like this would be the best thing that could happen.”

Two weeks later, he authorized large-scale bombing alongside Israel. The strikes killed Iran’s supreme leader, struck nuclear and military sites and sparked violence across the region.In public, Trump seemed to hesitate between negotiation and confrontation. But behind closed doors, according to people familiar with the discussions, his shift toward military action has gained momentum, encouraged by Netanyahu and bolstered by Trump’s confidence after previous foreign operations.According to the New York Times, Trump’s move toward war has gained momentum behind the scenes, driven by allies like Netanyahu and his own personal confidence. This is after previous American operations abroad.The newspaper reported that the decision was based on accounts from officials with direct knowledge of the deliberations, many of whom spoke anonymously due to the sensitivity of the discussions.For Netanyahu, the US entry into the war was a strategic victory. Months ago, at a meeting in Florida, he sought approval to strike Iranian missile sites. Instead, he got something bigger: a full American partner in a campaign that reshaped the Middle East overnight.

All details of the operation may not be shown at all. Intelligence methods remain closely guarded. But what is clear is that the strike on Khamenei was the culmination of years of surveillance, technological precision, and political resolve, a moment when intelligence, timing, and force converged with historic consequences.
