Warren P. Strobel. Nilo Tabrizy and John Hudson \u2013 The Washington Post Dec 17, 2025<\/strong><\/h1>\n<p>Preparations for war were almost complete. Scores of trained agents working for Israel were on the ground in Iran, armed with sophisticated new weapons. Israeli air force pilots were on standby for orders to attack Iran\u2019s nuclear infrastructure, ballistic missile launchers and air defenses. Israel and the United States, its chief backer, had argued their way to rough agreement on how close Tehran was to achieving a nuclear weapon. Diplomatic ruses were underway to blind Iran to the coming assault.<\/p>\n<p>But Israeli security officials knew that to do more than fleeting damage to Iran\u2019s sprawling nuclear program, they also had to decimate the \u201cbrain trust,\u201d a generation of Iranian engineers and physicists who U.S. and Israeli intelligence officials believed were working on the dark arts of turning fissile nuclear material into an atomic bomb.<\/p>\n<p>At about 3:21 a.m. on June 13, in the opening minutes of Israel\u2019s 12-day war with Iran, Israeli weapons began slamming into apartment blocks and homes in the Iranian capital. Operation Narnia, the campaign against Iran\u2019s top nuclear scientists, was underway.<\/p>\n<p>Mohammad Mehdi Tehranchi, a theoretical physicist and explosives expert under U.S. sanctions for his nuclear weapons work, was killed in his sixth-floor Tehran apartment in a building known as the Professors Complex. Fereydoun Abbasi, a nuclear physicist who once led Iran\u2019s atomic energy organization and was under U.S. and U.N. sanctions, died in another strike in Tehran two hours later. In all, Israel said, it assassinated 11 senior Iranian nuclear scientists on June 13 and in the following days.<\/p>\n<p>The massive, multipronged Israeli and U.S. attacks on Iran\u2019s nuclear program convulsed the Middle East, sparked promises of Iranian revenge, and, for now, have tanked the possibility of a diplomatic agreement to curb Tehran\u2019s nuclear work and place it under tight international controls.<\/p>\n<p>The Washington Post, together with PBS \u201cFrontline,\u201d has uncovered new details about the attacks, the planning behind them and their impact in Iran. This report is based on interviews with multiple current and former Israeli, Iranian, Arab and U.S. officials, some of whom spoke to reporters for the first time and on the condition of anonymity to describe secret operations and assessments.<\/p>\n<p>Iran\u2019s nuclear work probably has been set back years, officials from Israel, the United States and the United Nations\u2019 International Atomic Energy Agency said. But that is far from President Donald Trump\u2019s claim that the program was \u201ccompletely and totally obliterated.\u201d<\/p>\n<p>And Iran, which says its nuclear development is for civilian nuclear energy \u2014 not weapons, remains defiant.<\/p>\n<p>Amir Tehranchi told \u201cFrontline\u201d that his brother Mohammad\u2019s work would go on. \u201cWith the killing of these professors, they might be gone, but their knowledge isn\u2019t lost to our country,\u201d he said.<\/p>\n<p>Israel had assassinated Iranian scientists before, but always with deniability. Agents on motorcycle had slapped magnet bombs to scientists\u2019 cars in Tehran traffic. Abbasi narrowly survived such an attempt in 2010. Mohsen Fakhrizadeh, a prominent nuclear scientist, was killed by a remote-controlled machine gun <a href=\"https:\/\/www.washingtonpost.com\/world\/middle_east\/iran-nuclear-scientist-killed\/2020\/11\/27\/dede5c1c-30bb-11eb-9dd6-2d0179981719_story.html\">in an ambush<\/a> outside the Iranian capital in 2020.<\/p>\n<p>But in June, Israel\u2019s hand came out of the shadows. It had become emboldened as it openly decimated Iranian proxies in the Gaza Strip, Lebanon and Syria.<\/p>\n<p>We finally had an \u201coperational opportunity to do it,\u201d said an Israeli air force general who helped plan the assault on Iran.<\/p>\n<p>For Operation Narnia, Israeli intelligence analysts assembled a list of the 100 most important nuclear scientists in Iran, then whittled the target roster down to roughly a dozen. They built dossiers on each man\u2019s work, their movements, their homes \u2014 drawing on decades of espionage.<\/p>\n<p>The operation wasn\u2019t flawless. The Post and open-source investigative outlet Bellingcat were able to independently verify 71 civilian casualties in five strikes where nuclear scientists were targeted, using satellite imagery, video geolocation, death notices, cemetery records and coverage of funerals in Iranian media.<\/p>\n<p>The Post and Bellingcat confirmed that 10 civilians, including a <a href=\"https:\/\/www.golzar.info\/351121\/%d8%b4%d9%87%db%8c%d8%af-%d8%b1%d8%a7%db%8c%d8%a7%d9%86-%d9%82%d8%a7%d8%b3%d9%85%db%8c%d8%a7%d9%86\/\">2-month-old infant<\/a>, were killed in the strike on the Professors Complex in Tehran\u2019s Saadat Abad neighborhood. Witness accounts, combined with videos and images of the blast and resulting structural damage, indicate that the strike was similar to the force of a roughly 500-pound bomb.<\/p>\n<p>Israel targeted another scientist, Mohammad Reza Sedighi Saber, at his Tehran home during the opening wave of strikes. Sedighi Saber wasn\u2019t there, but his <a href=\"https:\/\/t.me\/astanehye_ashrafiyeh\/71886\">17-year-old son<\/a> was killed.<\/p>\n<p>On the conflict\u2019s last day, June 24, the elder Saber was killed at his relative\u2019s home about 200 miles from the capital, in Astaneh-ye Ashrafiyeh in Gilan province. A resident there, who spoke on the condition of anonymity for fear of government reprisals, told The Post that Saber had returned to his family home for his son\u2019s mourning ceremony and was killed alongside other relatives. The Post verified 15 civilian deaths in this strike, including four minors. Two residences were leveled, <a href=\"https:\/\/t.me\/VahidOnline\/66754\">leaving behind two craters <\/a>where the homes once stood.<\/p>\n<p>Israeli security officials said they did everything possible to limit civilian casualties. \u201cOne of the major considerations for the planning of Operation Narnia was to try to minimize as much as possible the collateral damage,\u201d a senior Israeli military intelligence officer said.<\/p>\n<p>Brig. Gen. Elad Edri, chief of staff of Israel\u2019s Home Front Command headquarters, said Iran\u2019s retaliatory strikes hit schools, hospitals and other civilian sites, killing 31 Israelis. A spokesperson for the Iranian government <a href=\"https:\/\/www.iranintl.com\/en\/202507221507\">said in July<\/a> that 1,062 people were killed in the Israeli strikes, including 276 civilians.<\/p>\n<div align=\"center\">\n<blockquote class=\"twitter-tweet\">\n<p dir=\"ltr\" lang=\"en\">Iran reveals the identities of Israeli pilots involved in bombing its civilian areas during the 12-day aggression.<\/p>\n<p>Follow Press TV on Telegram: <a href=\"https:\/\/t.co\/LWoNSpkc2J\">https:\/\/t.co\/LWoNSpkc2J<\/a> <a href=\"https:\/\/t.co\/W6pm8pJdez\">pic.twitter.com\/W6pm8pJdez<\/a><\/p>\n<p>\u2014 Press TV \uf53b (@PressTV) <a href=\"https:\/\/twitter.com\/PressTV\/status\/1951772996714025180?ref_src=twsrc%5Etfw\">August 2, 2025<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<\/div>\n<h2 style=\"text-align: center;\"><strong>Special weapons and sleeper agents<\/strong><\/h2>\n<p>Israel named the wider Iran campaign Rising Lion. Israeli warplanes and drones, along with agents inside Iran, destroyed more than half of Iran\u2019s ballistic missile launchers and shredded its remaining air defenses. Strikes decapitated the leadership of Iran\u2019s military and Islamic Revolutionary Guard Corps. Israeli warplanes bombed electric plants and ventilation systems that Iran needed to operate centrifuges purifying uranium at Natanz and Fordow, the country\u2019s main enrichment sites. Massive strikes from U.S. B-2 Spirit stealth bombers and a barrage of Tomahawk cruise missiles followed.<\/p>\n<p>Inside Iran, Israel\u2019s Mossad spy service mobilized more than 100 Iranian agents, equipping some of them with a three-part \u201cspecial weapon\u201d for precision strikes on military assets, said a senior Israeli security official with direct involvement in the planning.<\/p>\n<p>Iranian authorities recovered some of the launchers, but not the missiles or a secret third component, the senior Israeli security official said.<\/p>\n<p>The teams of Iranian agents were trained in Israel and elsewhere. They were told only their mission, not the full scope of what Israel was preparing. \u201cThis operation is unprecedented in history,\u201d the official said. \u201cWe mobilized our own assets and agents to go close to Tehran and launch the ground operation before the [Israeli] Air Force could enter Iranian airspace.\u201d<\/p>\n<p>Israel for decades had pondered a massive assault on Iran\u2019s nuclear program and other targets. But the potential obstacles fell away one by one as Prime Minister Benjamin Netanyahu ordered the destruction of Israel\u2019s enemies following Hamas\u2019s Oct. 7, 2023, attack.<\/p>\n<p>The Hamas assault killed roughly 1,200 people, precipitating Israel\u2019s siege of the Gaza Strip, which decimated Hamas\u2019s military arm and has left more than 70,000 Palestinians dead, according to Gaza health authorities. An even more fearsome Tehran proxy, Hezbollah, was gutted by relentless airstrikes across Lebanon and a spectacular Mossad operation that triggered <a href=\"https:\/\/www.washingtonpost.com\/world\/2024\/10\/05\/israel-mossad-hezbollah-pagers-nasrallah\/\">explosives hidden in booby-trapped pagers<\/a> used by the group. Longtime Hezbollah leader Hasan Nasrallah was killed in a September 2024 Israeli <a href=\"https:\/\/www.washingtonpost.com\/obituaries\/2024\/09\/28\/hasan-nasrallah-hezbollah-lebanon-dies\/\">airstrike<\/a>.<\/p>\n<p>Other developments spurred Israel\u2019s planning, officials said. The Syrian regime of President Bashar al-Assad, a longtime Iranian ally, collapsed in December 2024. Israel took advantage of the power vacuum, decimating what remained of Syria\u2019s military capability with hundreds of bombs and missile strikes, then occupying a swath of strategic territory in the country\u2019s southwest.<\/p>\n<p>Meanwhile, sporadic hostilities continued. Iran fired missiles and drones at Israel in April 2024, after Israel struck an Iranian Embassy building in Damascus, the Syrian capital, and killed three top Iranian commanders, and again that October after Israel assassinated Hamas political leader Ismail Haniyeh in Tehran. Israel retaliated with airstrikes and shot down the vast majority of Iran\u2019s incoming missiles and drones, blunting any future retaliatory threat from Tehran. In the second exchange, Israel destroyed sophisticated Russian S-300 air defense systems that could have posed a threat during Operation Rising Lion.<\/p>\n<p>The Israeli air force general said the decimation of Hezbollah and Assad\u2019s fall were key. \u201cPlans changed along the years, but they became very concrete after those two events,\u201d he said.<\/p>\n<h2 style=\"text-align: center;\"><strong>Nuclear nuances<\/strong><\/h2>\n<p>Israel and the United States, under both President Joe Biden and Trump, agreed that Iran was working toward a nuclear weapon. But their spy agencies sometimes diverged in their assessments of what Iranian scientists were doing and what it meant.<\/p>\n<p>Beginning in 2023, the CIA gathered intelligence that researchers working for a unit in Iran\u2019s Defense Ministry known as the SPND were exploring ways to more quickly build a nuclear weapon \u2014 if Ayatollah Ali Khamenei, Iran\u2019s supreme leader, reversed his 2003 religious injunction, known as a fatwa, against atomic weapons.<\/p>\n<p>The Iranians were researching a crude nuclear device, one that would take about six months to produce using its existing caches of enriched uranium, the CIA assessed. The primitive device could not be tested beforehand or delivered from afar by a ballistic missile, but it would be devastating all the same if built and used.<\/p>\n<p>The Iranians also appeared to be researching fusion weapons, a more advanced and powerful type of nuclear bomb. U.S. and Israeli intelligence analysts agreed that a fusion bomb, while concerning, was beyond Iran\u2019s reach.<\/p>\n<p>Iran had started producing significantly more enriched uranium after Trump in 2018 pulled out of an international deal limiting its nuclear activities. Neither the CIA nor Mossad believed Iran had begun constructing a bomb. But by spring 2025, Israeli analysts weren\u2019t certain that Khamenei would publicly announce a reversal of his fatwa or that they would be able to detect in time that Iran was assembling a weapon.<\/p>\n<p>On June 12, the eve of Operation Rising Lion, the IAEA declared Tehran in violation of its nonproliferation obligations \u2014 the first such reproach in 20 years.<\/p>\n<p>&nbsp;<\/p>\n<div align=\"center\">\n<blockquote class=\"twitter-tweet\">\n<p dir=\"ltr\" lang=\"en\">Newly released footage shows how Iranian missiles targeted the Israeli regime\u2019s buildings during the imposed 12-day war.<\/p>\n<p>Follow: <a href=\"https:\/\/t.co\/mLGcUTSA3Q\">https:\/\/t.co\/mLGcUTSA3Q<\/a> <a href=\"https:\/\/t.co\/uvTEKdgjvM\">pic.twitter.com\/uvTEKdgjvM<\/a><\/p>\n<p>\u2014 Press TV \uf53b (@PressTV) <a href=\"https:\/\/twitter.com\/PressTV\/status\/1964818614009446452?ref_src=twsrc%5Etfw\">September 7, 2025<\/a><\/p><\/blockquote>\n<p><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script><\/p>\n<\/div>\n<p>&nbsp;<\/p>\n<h2 style=\"text-align: center;\"><strong>Diplomacy and disinformation<\/strong><\/h2>\n<p>When Netanyahu visited Trump at the start of the U.S. leader\u2019s second term \u2014 the first foreign leader to do so \u2014 he presented four visions of how the assault on Iran could unfold, said a person familiar with the matter, who spoke on the condition of anonymity to describe private diplomatic exchanges.<\/p>\n<p>The Israeli prime minister first showed Trump what the operation would look like if Israel attacked alone. The second option was for Israel to take the lead, with minimal U.S. support. The third was full collaboration between the two allies. The last option was for the U.S. to take the lead.<\/p>\n<p>Months of stealthy, intensive strategic planning commenced. Trump wanted to give nuclear diplomacy with Iran a chance, but he continued intelligence-sharing and operational planning with Israel, two people familiar with the matter said. \u201cThe thinking was, if talks fail, we are ready to go,\u201d one person said.<\/p>\n<p>Israel\u2019s leaders thought that giving diplomacy a chance was important for global public opinion if they ultimately decided to strike Iran. But they also worried that Trump, in his eagerness for a deal, might agree to a bad one.<\/p>\n<p>In mid-April, Trump gave Iran 60 days to agree to a nuclear deal. The deadline expired Thursday, June 12. He and Netanyahu maneuvered to keep the Iranians unprepared for what would happen next.<\/p>\n<p>Trump told reporters on June 12 that an Israeli strike on Iran \u201ccould very well happen\u201d but indicated he preferred a negotiated solution. Israeli officials leaked word that top Netanyahu adviser Ron Dermer and Mossad chief David Barnea would soon meet U.S. special envoy Steve Witkoff. A new round of U.S.-Iranian nuclear talks was scheduled for Sunday, June 15.<\/p>\n<p>Israel had decided to strike, as the U.S. well knew. The planned diplomacy was a ruse, and officials from both countries encouraged media reports of a U.S.-Israeli rift.<\/p>\n<p>\u201cAll the reports that were written about Bibi not being on the same page with Witkoff or Trump were not true,\u201d the person familiar with the matter said, using Netanyahu\u2019s nickname. \u201cBut it was good that this was the general perception, it helped to move on with the planning without many people noticing it.\u201d<\/p>\n<p>Even after the Israeli bombing and assassination campaign began, the Trump administration made a final diplomatic push. It secretly transmitted a proposal to Iran to resolve the standoff over its nuclear program. What Iran did not know was that this overture would be its final opportunity before Trump approved U.S. firepower joining Israel\u2019s.<\/p>\n<p>The terms of the deal, obtained by The Post and not previously reported, were steep and included Tehran ending support for proxies such as Hezbollah and Hamas, as well as \u201creplacing\u201d the Fordow Fuel Enrichment Plant and \u201cany other functioning facility\u201d with alternative facilities that do not allow enrichment. In return, the U.S. would lift \u201cALL sanctions placed on Iran,\u201d the proposal, dated June 15, says.<\/p>\n<p>Shortly after the U.S. transmitted the proposal to Iran via Qatari diplomats, Tehran rejected it, and Trump authorized U.S. strikes, a senior diplomat involved in the process said.<\/p>\n<h2 style=\"text-align: center;\"><strong>\u2018Can\u2019t take the discovery away\u2019<\/strong><\/h2>\n<p>U.S., Israeli and IAEA officials say the damage to Iran\u2019s nuclear program, while not complete, is significant \u2014 setting the program back years and probably ending for now Iran\u2019s ability to enrich uranium that could be used to fuel a nuclear weapon.<\/p>\n<p>\u201cOverall, the damage caused by airstrikes to numerous nuclear sites was extensive and, in many cases, catastrophic,\u201d the Institute for Science and International Security said in a November assessment based in part on satellite imagery.<\/p>\n<p>Israeli officials say the Iranian program has been \u201csignificantly delayed,\u201d with the Natanz enrichment site destroyed, portions of the Isfahan nuclear research complex obliterated and the deeply buried enrichment site at Fordow severely damaged.<\/p>\n<p>IAEA Director General Rafael Mariano Grossi told \u201cFrontline\u201d that damage is \u201cvery substantial.\u201d Iran, he said, retains its stockpile of almost 900 pounds of uranium enriched to 60 percent purity, a step away from the 90 percent needed for a nuclear weapon. The stockpile, he said, \u201cis where it was by and large,\u201d at Isfahan, Fordow and Natanz. Whether Iran can access the material is unclear, and IAEA inspectors have been barred from accessing key facilities since the strikes.<\/p>\n<p>\u201cObviously, without having physical access to a place, any evaluation is partial,\u201d Grossi said.<\/p>\n<p>The Post reported in September that, since the 12-day war ended, Iran has <a href=\"https:\/\/www.washingtonpost.com\/national-security\/2025\/09\/26\/iran-underground-nuclear-us\/\">increased construction<\/a> at a mysterious underground site just south of Natanz known as Pickaxe Mountain. Iran is also attempting to rebuild its ballistic missile inventory with help from China, Israeli officials and U.S.-based analysts told The Post.<\/p>\n<p>Trump has threatened strikes if Iran enriches uranium at a high level again.<\/p>\n<p>Ali Larijani, secretary of Iran\u2019s Supreme National Security Council, was unmoved in an interview with \u201cFrontline,\u201d his first with foreign media since the June war. \u201cIran\u2019s nuclear program can never be destroyed,\u201d he said. \u201cBecause once you have discovered a technology, they can\u2019t take the discovery away.\u201d<\/p>\n<p><em>Jarrett Ley, Sebastian Walker, Adam Desiderio, Trevor Ball, Carlos Gonzales, Eoghan Macguire and Sebastian Vandermeersch contributed to this report.<\/em><\/p>\n<p><a href=\"https:\/\/www.washingtonpost.com\/national-security\/2025\/12\/17\/iran-israel-war-nuclear-scientists-frontline-pbs\/\">Source\u00a0<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>How U.S. negotiators used the promise of a peaceful solution and a combination of diplomacy and disinformation to blind Iran to Israel\u2019s looming strikes in June 2025 <\/p>\n","protected":false},"author":39262,"featured_media":310342,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_et_pb_use_builder":"","_et_pb_old_content":"","_et_gb_content_width":"","footnotes":""},"categories":[51,37],"tags":[],"class_list":["post-320182","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-Iran","category-Israel_Anti-Semitism_Zionism_and_US-UK_allies"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/320182","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/users\/39262"}],"replies":[{"embeddable":true,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=320182"}],"version-history":[{"count":6,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/320182\/revisions"}],"predecessor-version":[{"id":320206,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/posts\/320182\/revisions\/320206"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=\/wp\/v2\/media\/310342"}],"wp:attachment":[{"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=320182"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=320182"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.thetruthseeker.co.uk\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=320182"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
