Iran has established a new Defense Council under the Supreme National Security Council (SNSC), aiming to centralize military decision-making and prepare for crises ranging from war to potential leadership transition.
According to the SNSC Secretariat’s August 3 announcement, the council’s core responsibility is to enable swift, centralized defense decisions in wartime or national emergencies.
While it functions under Article 176 of Iran’s constitution alongside other SNSC sub-bodies—analysts say its timing and composition signal deeper institutional concerns.
Why now?
The move comes amid heightened tensions with Israel and the United States, and growing doubts over Iran’s ability to respond quickly in moments of crisis.
Abdulrasool Divsalar of the United Nations Institute for Disarmament Research said on X that Iran’s delayed response to Israel’s June attacks exposed “a crisis in the strategic military decision-making structure.”
Without secure digital infrastructure, he said, assembling the full SNSC during wartime could be dangerously slow and vulnerable to decapitation strikes.
The new council, by concentrating authority in a smaller group of key officials, is designed to reduce those risks.
MP Mohammad-Esmaeil Kowsari told Jamaran the Defense Council avoids the SNSC’s sluggish consensus model, replacing it with a “smaller, more focused group—allowing for faster and more effective decision-making.”
Lawmaker Mohammad Seraj added that in wartime, “any decision made by the Defense Council is equivalent to one made by the SNSC.”
Function and composition
The council will be chaired by the President and include the heads of the Judiciary and Parliament, two SNSC representatives appointed by the Supreme Leader, the Intelligence Minister, and the Chief of the General Staff.
A key difference from the SNSC is the Defense Council’s permanent inclusion of the top commanders of the Army, the IRGC, and the Khatam-al-Anbia Central Headquarters, which oversees joint military operations.
Though officially a sub-body, some observers see the council as more than a bureaucratic fix.
Writing in Ham Mihan, journalist Ahmad Zeidabadi called it “a move to re-centralize fragmented political authority amid a time of crisis,” alluding to doubts over what might happen if Supreme Leader Ali Khamenei becomes incapacitated.
In that case, the President—who chairs both the SNSC and Defense Council—would be the highest-ranking official in the country.
Institutional context
While the SNSC has long held final authority over Iran’s national security matters, its broad membership—spanning political, military, and economic leaders—makes it unwieldy in urgent situations.
Several lesser-known sub-councils already function under its umbrella, including the Passive Defense Council for critical infrastructure, the Intelligence Coordination Council made up of agency chiefs, and the National Security Council chaired by the Interior Minister.
The Defense Council is distinct in its mandate and composition: focused exclusively on defense, it aims to function as a standing wartime command center. Like the SNSC, its decisions require final approval from the Supreme Leader.

Veteran powerbroker Ali Larijani has been reappointed as Secretary of Iran’s Supreme National Security Council (SCNS), returning to a role from which he resigned two decades ago after clashes with ultra-hardline President Mahmoud Ahmadinejad.
His comeback underscores not only his enduring relevance in Iran’s power circles but also a career defined by strategic shifts, navigating factions and consistent loyalty to the country’s ultimate authority Supreme Leader Ali Khamenei.
For much of his career, Larijani was known as a staunch conservative.
He vocally opposed reformist President Mohammad Khatami and the broader reform movement, using his position as head of the state broadcaster IRIB to discredit Iranian intellectuals.
The program Hoviat ("Identity") targeted cultural figures like poet Ali Akbar Saeedi Sirjani, some of whom were later victims of the Intelligence Ministry’s multiple targeted murders.
‘Problem solver’
Yet by 2015, Larijani emerged as a key supporter of the Iran nuclear deal, helping secure its approval in parliament in under 20 minutes despite conservative opposition. The move aligned him with then-president Hassan Rouhani and marked a dramatic pivot from his earlier hardline stance.
Khamenei publicly praised Larijani at the time as a "problem-solver," though his growing closeness to Rouhani reportedly raised eyebrows in the Supreme Leader’s inner circle.
Larijani was blocked twice from running for president in 2021 and 2024
Throughout these shifts, Larijani remained attuned to the political winds.
His alliances with Presidents Akbar Hashemi Rafsanjani and Khatami cooled as soon as Khamenei distanced himself from them—underscoring a deeper, more consistent alignment with the Supreme Leader over any political faction.
Return to the fold
Despite being sidelined in recent presidential elections—disqualified by the Guardian Council in both 2021 and 2024 allegedly over his daughter studying abroad—Larijani has evidently regained the trust of Iran's theocrat.
Following President Ebrahim Raisi’s death last yer, he was handed two sensitive tasks: overseeing the Iran-China strategic accord and acting as an intermediary with Russia after Israeli strikes on Iranian soil.
While many establishment figures kept a low profile during the crisis, Larijani reemerged as a visible supporter of the Islamic Republic and its top leadership.
An operator without a party
Though courted by moderate conservatives to form a party during Rouhani’s presidency, Larijani resisted. One reason may be his limited popular base.
In parliament, he represented Qom, where a few thousand votes suffice to win a seat—far fewer than the million-plus votes typically needed in Tehran.
Larijani’s political instincts appear rooted more in elite maneuvering than popular mobilization, consistent with his background in a deeply clerical family tied to the seminaries of Qom and Najaf.
The Larijani legacy
Ali Larijani is part of one of Iran’s most influential political dynasties. His father, Hashem, was a respected cleric who steered clear of politics, but his sons embraced the Islamic Republic’s institutions.
Ali's four brothers have held senior roles across Iran’s judicial, legislative and security branches. Ali, the only full-time politician in the family, carved out a career that included 12 years as Speaker of Parliament, top roles in the media and culture ministries and ongoing membership in the Expediency Council.
Educated at the Qom Seminary and Tehran University—where he earned a PhD in Western philosophy—Larijani blends ideological training with technocratic credentials.
He is married to the daughter of Ayatollah Morteza Motahari, a key architect of the Islamic Republic, further cementing his position within Iran’s ruling elite.
A Loyal chameleon
While Larijani now often echoes hardline rhetoric against the United States, he has occasionally voiced cautious support for dialogue.
Deeply skeptical of Europe but pragmatic when necessary, he remains one of the few establishment figures with the credentials and adaptability to help steer Iran toward diplomatic de-escalation, should that path ever open.
Few Iranian politicians have changed stripes as fluidly as Larijani. Yet through all the turns—from hardliner to moderate broker, from sidelined veteran to high-level envoy—his loyalty to Khamenei has never wavered.
In a system where ideological purity is often less important than proximity to the Supreme Leader, Larijani has mastered the art of staying close to the only power that truly matters.
A high-profile conservative seen as close to Iran's Supreme Leader Ali Khamenei has been appointed to lead Iran’s newly revamped Supreme National Security Council, Tasnim News reported on Tuesday.
Ali Larijani replaces Ali Akbar Ahmadian, who is due to take on an unspecified new role in the administration of President Masoud Pezeshkian, Tasnim added.
Larijani previously served three terms as speaker of parliament, secretary of the Supreme National Security Council, head of the Islamic Republic of Iran Broadcasting (IRIB), Minister of Culture and Islamic Guidance and advisor to the Supreme Leader.
His appointment may signal a doubling down on Tehran's traditional confrontational stance with Israel and the United States after a punishing 12-day war with Israel in June capped off by US airstrikes on Iranian nuclear sites.
Still, Larijani registered three time to run for president in Iran but was disqualified on two occasions by Iran's hardliner-dominated Guardian Council. His political stances on diplomacy and domestic affairs appear to have softened in recent years.
Larijani ran as a candidate in the ninth presidential election of Iran, held in 2005. He lost the race, finishing sixth out of seven candidates.
The appointment comes with some institutional changes following a 12-day war with Israel in June.
President Pezeshkian will chair the council, which will include the heads of the executive, legislative and judiciary branches, as well as top military commanders and key cabinet ministers, the report added.
A son of a former Iranian intelligence chief has been charged with supporting Israel and was banned from using social media for three months, Hassan Younesi announced on his X account, amid a sweeping postwar crackdown by Iranian authorities.
"I have been banned from activity on social media for three months. Turns out that in addition to spreading ‘falsehoods and propaganda against the sacred system,’ I am also accused of ‘strengthening the Zionist regime,’” said Younesi, a former advisor to former president Hassan Rouhani.
His father Ali Younesi was intelligence minister during Mohammad Khatami’s presidency.
In past public remarks, Hassan Younesi had warned of deep infiltration by Israel’s Mossad in Iran, saying officials should be concerned for their personal safety.
Younesi, who is also a lawyer, was briefly detained in November 2022 amid Iran’s nationwide protests sparked by the death in custody of 22-year-old Mahsa Amini over an alleged hijab law violation.
The charge against Younesi comes amid a broader crackdown on dissent and alleged espionage during and after the 12-day war with Israel.
More than 700 people were arrested in the month after the ceasefire, mostly accused of working as agents for Israel in recent days.
The arrests reportedly targeted what authorities described as an “active espionage and sabotage network” that intensified operations following Israel’s June 12 strike, which killed several senior Iranian military and nuclear figures.
An Iranian delegation including nuclear scientists with ties to a sanctioned military research unit travelled to Russia last year to visit institutes producing dual-use technologies, the Financial Times reported on Tuesday.
The visit, in August 2024, was led by Ali Kalvand, a 43-year-old Iranian nuclear physicist, who arrived in Moscow on a diplomatic service passport along with four others, according to the report.
While Kalvand said they represented a private consulting firm, Western officials told the newspaper the delegation included a military counter-intelligence officer and members linked to Iran’s Organization of Defensive Innovation and Research (SPND), described by the US as “the direct successor organization to Iran’s pre-2004 nuclear weapons program.”
Iran has long denied seeking nuclear weapons, citing a religious edict by Supreme Leader Ali Khamenei banning their use, and says its nuclear activities are entirely peaceful. Khamenei said last month that the West uses Tehran’s nuclear program as an excuse for confrontation.
Iran International reported last year, citing three independent sources in Iran, that the Islamic Republic was advancing its secret nuclear weapons program by restructuring the SPND.
According to the Financial Times, the Iranian delegation met with Russian companies that manufacture dual‑use components, including electron accelerators and klystrons — equipment used in nuclear implosion simulations.
The delegation’s members also included experts in neutron generators – devices with civilian and military applications – and radiation testing, as well as a former head of a company sanctioned by Washington for acting as a procurement front for SPND.
Tritium request raises concern
The Iranian delegation also sought access to radioactive isotopes such as tritium, a substance with civilian uses but strictly controlled under global non‑proliferation rules because of its role in enhancing the yield of nuclear warheads.
The report said it reviewed a letter from Kalvand’s firm to a Russian supplier in May 2024 expressing interest in acquiring several isotopes, including tritium.
“It’s disturbing that these types of people can have this type of meeting in Russia, given the state Russia and Iran are in,” said Pranay Vaddi, a former senior director for non-proliferation at the US National Security Council.
“Regardless of whether the Russians are sharing components or technology, SPND is an organization who would be applying that specifically to nuclear weapons work.”
David Albright, head of the Institute for Science and International Security, told the paper: “We consider that a type of nuclear weapons program — to shorten the timeline... The leadership didn’t want to make a decision to build a weapon for various reasons. This sort of research activity allowed the leadership to say there was no nuclear weapons program.”
What is SPND?
SPND was established in 2011 by Mohsen Fakhrizadeh, who Western intelligence agencies believed oversaw Iran’s earlier nuclear weapons program, known as the Amad Plan, before it was halted in 2003. The US and the International Atomic Energy Agency (IAEA) consider SPND its institutional successor.
The US has repeatedly sanctioned SPND and affiliated companies, citing their role in “dual-use research and development activities applicable to nuclear weapons and nuclear weapons delivery systems.”
In 2024, Iran’s parliament formally recognized SPND under Iranian law, placing it under the defense ministry and exempting its budget from parliamentary oversight.
During Israeli attacks on Iran in June, Saeed Borji, a senior Iranian explosives expert and key figure in Iran’s nuclear-related defense programs, was killed. He headed the Center for Explosion and Impact Technology Research (known by its Persian acronym Metfaz), a subsidiary of the SPND.
Also among the delegates was Soroush Mohtashami, a neutron‑generator specialist trained under Fereydoon Abbasi‑Davani, who was also killed in the June attacks that, according to Israel, left at least nine scientists dead.
At the time, the military said all those killed had worked on the complex engineering mechanism that triggers the uranium core’s nuclear explosion.
Ian Stewart, head of the Washington office of the James Martin Center for Nonproliferation Studies, told the newspaper: “While there could be benign explanations for these visits, the totality of the information available points to a possibility that Iran’s SPND is seeking to sustain its nuclear weapons-related knowhow by tapping Russian expertise.”
Tehran has requested the Taliban share a leaked list of Afghans who assisted British forces, including those linked to MI6, as part of a bid to identify and potentially detain some now in Iran for possible diplomatic leverage ahead of nuclear talks, The Telegraph reported.
An official from the Islamic Revolutionary Guard Corps (IRGC) in Tehran confirmed to The Telegraph on Monday that the IRGC has formally asked the Taliban for the list of nearly 25,000 Afghans.
The list, dubbed the “kill list” in British media was leaked in 2022 and contains the full names, emails, and phone numbers of people in Afghanistan who applied for relocation to the United Kingdom following the military withdrawal in 2021.
It includes personal data of Afghan soldiers, government employees, and their families, as well as around 100 British special forces members and intelligence operatives who had endorsed Afghan applicants.

A Taliban official told The Telegraph that since discovering the value of the list, the group has been working to locate and detain those still in Afghanistan, intending to use them as leverage in diplomatic pressure on the UK.
"Taliban leadership in Kandahar has also ordered officers in Kabul to arrest as many individuals as possible from the leaked document to use them as leverage in exerting diplomatic pressure on London," according to the report.
The Telegraph says the IRGC appears to have similar intentions, particularly with renewed nuclear negotiations and the threat of snapback sanctions looming over Iran.
Since the June 25 ceasefire between Iran and Israel, Tehran has accelerated the deportation of Afghan nationals from Iran, citing an inability to continue hosting large numbers of migrants and asylum seekers.
On July 25, senior Iranian diplomats met with counterparts from the UK, France, and Germany in Istanbul to discuss the path forward. They agreed to continue negotiations.
European governments are pressing Iran to resume full cooperation with the International Atomic Energy Agency (IAEA), including the reinstatement of inspections and other obligations. Following the war with Israel, Iran has moved to further limit cooperation with the UN nuclear watchdog.
Under UN Security Council Resolution 2231, any party to the now-lapsed 2015 nuclear agreement—including France, Germany, the UK, Russia, or China—can file a complaint accusing Iran of non-compliance.
If no progress is made on Iran's nuclear dossier by August 30, the so-called snapback mechanism can reinstate UN sanctions removed under the 2015 deal.
“We have made it clear to the United Nations and the Security Council that such a step is a misuse of international mechanisms, and the Islamic Republic will respond decisively,” Iran’s Deputy Foreign Minister Kazem Gharibabadi said Sunday.
