Former Iranian official Mohammad‑Javad Larijani said his country has developed a new theoretical doctrine: one in which a state capable of building a nuclear bomb in under two weeks chooses not to do so.
He pointed out that the fatwa by Supreme Leader Ali Khamenei against nuclear weapons has strong Shia jurisprudential foundations.
Larijani, a former senior judiciary official who also served as a top adviser to the Supreme Leader, added that he supports the expansion of Iran’s nuclear capabilities, framing them as a deterrent and emphasizing the country’s decision not to weaponize.
He also voiced sharp criticism of the 2015 nuclear deal, saying the so-called “diplomacy doctrine” of the Joint Comprehensive Plan of Action (JCPOA) had led Iran to “distress and reversed courage.”
Larijani, speaking at a conference examining the thoughts of Ali Khamenei, said that the JCPOA doctrine -- based on trading rights for concessions -- was akin to surrendering part of Iran’s rights in order to preserve others, and he invoked Iran’s war-era ethos of resisting aggressors.
Larijani’s comments reflect a nuanced position often heard from Tehran: while Iran signals that it remains technically close to nuclear weapon capability, it continues to assert that its policy remains peaceful and that the decision not to build such weapons stands.
The remarks come amid international scrutiny of Iran’s nuclear program, where questions remain over enrichment levels and stockpiles, and where the authenticity and legal force of Khamenei’s so-called fatwa have been contested by analysts.
International experts say the Iranian stance complicates diplomatic efforts, as Tehran’s acknowledgement of capability but insistence on conditional restraint leaves room for ambiguity.
Critics argue this could be designed to serve both as deterrence and diplomatic leverage.
The recent confrontation in June had shattered long-standing assumptions about Israel’s military power, Saeed Khatibzadeh said.
“The myth of Israel’s invincibility collapsed after Iran’s response,” he added, describing Tehran’s military action as a turning point that proved Iran’s capacity to retaliate.
Earlier this year, the United States held five rounds of negotiations with Tehran over its disputed nuclear program under a 60-day deadline set by President Donald Trump.
When no agreement was reached by the 61st day, on June 13, Israel launched a surprise military offensive, followed by US strikes on June 22 targeting key nuclear facilities in Isfahan, Natanz, and Fordow.
“Iran has no choice but to secure a decisive victory against the aggressor,” Khatibzadeh said, arguing that any attack on Iran would be met with a response aimed at ensuring that “the aggressor will undoubtedly regret its decision.”
‘We are peace-seeking, but we fight well’
Iran does not seek confrontation but will not hesitate to defend itself, Khatibzadeh said. “We are a peace-seeking people, but if war is imposed on us, we fight well… We never sought confrontation, but they chose the path of confrontation.”
The deputy minister linked Iran’s stance to what he called the “geopolitical ambitions” of the United States and Israel, urging other countries to recognize Iran’s right to defend itself.
“We have never accepted the language of force,” he said. “Our message is clear: respect, justice, and balance must define international relations.”
The 12-day conflict ended on June 24 after a US-brokered ceasefire, but global alarm over Tehran’s nuclear program deepened as 400 kilograms of Iran’s highly enriched uranium remained unaccounted for.
Tehran says the material lies buried beneath debris from US and Israeli airstrikes, rendering it unreachable, yet it has so far refused to grant international inspectors access to the damaged sites.
Foreign Minister Abbas Araghchi said Iran had managed the June war with Israel effectively and prevented it from spreading to the wider region, according to the Qatari network. He said Iran was fully prepared for any new confrontation and warned that Israel would face “another defeat” if fighting resumed.
Araghchi said Iranian nuclear sites were damaged in the war but its enrichment technology remained intact, with nuclear materials still at the bombed facilities.
He said Iran would not accept Western pressure and was ready for indirect talks with Washington to reach what he called a fair agreement on its nuclear program. Tehran was willing to address international concerns, he added, but would not make concessions after being attacked.
His remarks came a day after Egypt said it had urged both Iran and the International Atomic Energy Agency to end the standoff over inspections of damaged nuclear sites. Egyptian Foreign Minister Badr Abdelatty said he conveyed the appeal to Araghchi and IAEA chief Rafael Grossi in separate calls aimed at reviving cooperation.
Iran suspended full cooperation with the UN watchdog after the June war with Israel and the United States, which struck several nuclear facilities. Under a post-war law, inspections now require approval by Iran’s Supreme National Security Council and exclude access to the bombed sites.
Western powers accuse Tehran of hiding military dimensions to its program, while Iran insists its nuclear work is peaceful.
Tensions with Washington have sharpened after US President Donald Trump ordered the first American nuclear weapons tests in more than three decades. Araghchi called the move a regressive and irresponsible step and said it showed what he called US hypocrisy for condemning Iran’s nuclear work while restarting its own testing.
