Iran's Revolutionary Guards ready to change nuclear doctrine if Mojtaba orders

The brief

The striking point is that Iran has not announced a nuclear-policy reversal. IRGC spokesperson Brigadier General Hossein Mohebbi said necessary preparations would be made only if the country’s leadership decided to revise its nuclear doctrine. His statement describes a possible future decision, not a decision already taken. The mechanism is political authorization. Iran’s military establishment may prepare for a change, but the leadership must first give the order. Mohebbi did not explain what a revised doctrine would involve, and he did not say Tehran had abandoned its opposition to nuclear weapons. The remarks follow Mohsen Rezaei’s statement that officials were considering possible changes. Rezaei also said no decision had been made. The result is a significant change in rhetoric, while Iran’s formal nuclear policy remains publicly unchanged.

01

What did the IRGC spokesperson actually say, and does it mean Iran has already changed its nuclear policy?

The striking point is that Iran has not announced a nuclear-policy reversal. IRGC spokesperson Brigadier General Hossein Mohebbi said necessary preparations would be made only if the country’s leadership decided to revise its nuclear doctrine. His statement describes a possible future decision, not a decision already taken.

The mechanism is political authorization. Iran’s military establishment may prepare for a change, but the leadership must first give the order. Mohebbi did not explain what a revised doctrine would involve, and he did not say Tehran had abandoned its opposition to nuclear weapons.

The remarks follow Mohsen Rezaei’s statement that officials were considering possible changes. Rezaei also said no decision had been made. The result is a significant change in rhetoric, while Iran’s formal nuclear policy remains publicly unchanged.

02

What is a nuclear doctrine, and how does it guide a country's decisions about developing, possessing, or using nuclear weapons?

A nuclear doctrine is a country’s broad policy toward nuclear weapons. It covers whether the country seeks to develop them, keep them, deter threats with them, or potentially use them. It matters because doctrine turns political goals into guidance for military planning, diplomacy, and national-security decisions.

For Iran, the established position has been that its nuclear programme serves peaceful purposes and that it does not want nuclear weapons. The IRGC statement introduced a conditional alternative: if Iran’s leadership formally revises the doctrine, military preparations would follow. That links any operational change to a leadership decision.

Iran has not confirmed such a revision. Mohsen Rezaei said officials were considering possible changes but that no decision had been taken. Therefore, the doctrine remains publicly unchanged, although the warning suggests that Iran’s leadership is considering how its nuclear policy might respond to growing confrontation.

03

Who are the Islamic Revolutionary Guard Corps, and why would their statement matter in Iran's national-security decision-making?

The Islamic Revolutionary Guard Corps is Iran’s powerful military and security force. The article identifies it as part of Iran’s military establishment and names Hossein Mohebbi as its spokesperson. Because the IRGC is closely involved in national security, its public statements can signal how Iran’s security institutions view a developing crisis.

Mohebbi did not announce a policy change. He said the IRGC would make necessary preparations if Iran’s leadership decided to revise the nuclear doctrine. The key mechanism is the relationship between civilian leadership and military implementation: leaders would authorize the shift, while the IRGC would help prepare for its consequences.

That makes the statement important but not conclusive. It shows military readiness and sharper rhetoric amid confrontation with the United States and Israel. It does not establish that Iran has ordered nuclear-weapons development or abandoned its long-standing public position.

04

How much enriched uranium might Iran still possess, and how does enrichment to 60 percent compare with the roughly 90 percent level associated with weapons-grade uranium?

Iran may still possess more than 200 kilograms of uranium enriched to as much as 60 percent, according to an IAEA belief reported in a Reuters analysis. That level is well above what is normally required for civilian nuclear power. It matters because the material could provide a substantial starting point for further enrichment.

Enrichment increases the concentration of the uranium isotope needed for a nuclear chain reaction. The article places 60 percent below the roughly 90 percent level generally associated with weapons-grade uranium. The difference does not mean 60 percent material is a bomb, but it means the material is closer to that benchmark than ordinary civilian fuel.

The exact stockpile remains uncertain. The IAEA has struggled to verify where Iran’s enriched uranium and centrifuges are after military strikes. The article also says earlier assessments found Iran was not actively building a nuclear weapon.

05

What could happen to regional tensions and international efforts to restrain Iran if Iran's leadership formally ordered a change in nuclear doctrine?

A formal change would likely deepen tensions across the Middle East because it would replace a long-standing public rejection of nuclear weapons with an official possibility of pursuing them. Israel, the United States, and neighboring countries could view that move as a major security threat, especially after years of confrontation and recent military escalation.

The key mechanism would be the conversion of political doctrine into military preparations. Iran’s leadership could authorize steps that the IRGC said it was ready to undertake. International efforts would then focus more urgently on inspections, enrichment limits, and preventing further escalation. Strikes and countermeasures could also become harder to avoid.

The article does not say what would happen after a formal order. It does show that inspections are already difficult, that the IAEA cannot fully verify Iran’s material, and that the United States continues framing its policy around stopping an Iranian bomb. A doctrine shift would intensify that dispute.

06

Why has Iran historically said that its nuclear program is peaceful, and what role did Khamenei's religious decree against nuclear weapons play in that position?

Iran’s historical position is that its nuclear programme serves peaceful purposes, not weapons production. Tehran has repeatedly denied seeking a nuclear weapon. That claim has been central to its public explanation of enrichment and its response to accusations from the United States, Israel, and others.

Ayatollah Ali Khamenei, Iran’s slain Supreme Leader, issued a religious decree known as a fatwa. It declared the acquisition, development, and use of nuclear weapons forbidden under Islamic principles. The decree gave Iran’s stated opposition to nuclear weapons a religious foundation as well as a political one.

The recent IRGC warning therefore matters because it contrasts with that established position. It does not say Khamenei’s fatwa has been withdrawn or that Iran has adopted weapons development. The article presents the change as sharper rhetoric and possible preparation, while confirming that no formal policy shift has been announced.

07

How does uranium enrichment work, and why can material produced for civilian purposes become a proliferation concern even before a country has built a nuclear bomb?

Uranium enrichment separates and concentrates uranium isotopes, especially the isotope that can sustain a nuclear chain reaction. Centrifuges perform this work by spinning uranium-containing gas at high speed. Civilian reactors generally use lower-enriched fuel, while higher enrichment brings material closer to the level associated with nuclear weapons.

The article says Iran may still hold more than 200 kilograms enriched to up to 60 percent. That is below the roughly 90 percent level generally associated with weapons-grade uranium, but 60 percent material can theoretically be enriched further. The same basic process can therefore support civilian energy or create a proliferation concern.

This concern does not prove that Iran has built a bomb. The article notes that earlier assessments found Iran was not actively building one. However, stockpiles, centrifuges, and uncertainty about their locations make international verification more important, especially after military strikes.
