Iran holds to the nuclear treaty as hardliners raise the prospect of a bomb

Tehran says the treaty stands, the inspectors return to one plant

On Monday 9 November, Iran's foreign ministry spokesman Esmaeil Baghaei told reporters in Tehran that Iran has not suspended its commitments under the Treaty on the Non-Proliferation of Nuclear Weapons, and that it remains a party to the treaty. The statement came as mediated talks to end the war with the United States continue, and as the question of whether Iran will keep the treaty or leave it has moved from the margins of Iranian politics to the centre.

Baghaei confirmed that inspectors from the International Atomic Energy Agency visited the Bushehr nuclear power plant several days earlier; the first such inspection he has publicly confirmed in months. Bushehr, built with Russian cooperation, is the only Iranian nuclear facility still open to the agency, because it was not directly bombed during the war.

One plant open, three closed, and a warning from Vienna

The inspection at Bushehr is real but narrow. The plant generates electricity and was not directly hit, although American warplanes attacked its perimeter several times and caused damage, prompting the partial evacuation of Russian personnel who have yet to return in full. The sensitive sites, Natanz, Fordow and Isfahan, remain closed to inspectors, and Tehran has given no date for their reopening.

The agency's own position is on the record. Its director general, Rafael Grossi, told the United Nations Security Council in late October that the body was unable to verify Iran's nuclear material because Tehran "has not provided the requested information and access". Baghaei answered that criticism directly, saying the American and Israeli attacks had made normal cooperation impossible; and he renewed Tehran's criticism of Grossi himself.

At the same briefing, Baghaei pressed Iran's two-day plan for restoring security in the Strait of Hormuz; a reminder that the nuclear statement arrived as part of a wider diplomatic offer, and the talks it belongs to are the ones Qatar has been trying to bridge for weeks.

The stockpile, the successor, and the red line nobody has drawn

Nobody outside Tehran knows how much highly enriched uranium Iran still holds, or where exactly it is. The agency cannot verify the material, and Tehran has said it will not allow the stockpile to leave the country; though it remains open to diluting it under international supervision inside Iran.

Nobody knows whether the hardliners' talk will become policy. The men pressing for a new doctrine have not been overruled, but no decision has been announced, and the power to decide rests with the leadership that succeeded the assassinated Supreme Leader Ali Khamenei; a leadership whose own position on the religious ban on nuclear weapons has yet to be stated in full.

And nobody knows what would trigger a withdrawal. The treaty allows a party to leave with three months' notice if it decides that extraordinary events have jeopardised its supreme interests; but Tehran has not said what, precisely, would meet that test.

Why does a treaty that cannot stop a bomb still matter?

Because the treaty is the only legal framework that keeps inspectors inside Iran at all, and because leaving it would remove the last outside check on a programme the agency already cannot verify. A withdrawal would not build a bomb by itself, but it would end the world's legal right to ask what Iran is building; and it would hand Washington and Jerusalem the argument that diplomacy has run out.

The timing matters too. President Donald Trump has threatened to attack the underground Pickaxe Mountain complex near Natanz, and has said further American strikes are highly unlikely while forces stay ready. Each threat strengthens the hardliners' case at home: the men arguing for a bomb say the treaty protected nothing, since the treaty's own members bombed Iran anyway.

One foot inside the treaty, one foot near the exit

The International Crisis Group's Ali Vaez put it plainly: Tehran is keeping one foot inside the treaty and the other near the exit. The Bushehr inspection is, in his words, a low-cost gesture designed to keep diplomacy alive and the hardliners at bay, while preserving leverage over the underground sites that matter most. It costs Tehran almost nothing, Bushehr is a power plant, not a weapons site, and it buys something real: proof, for the mediators, that cooperation has not ended entirely.

The former negotiator Seyed Hossein Mousavian draws the line differently. For him, Iran's position reflects a distinction between honouring its treaty commitments and permitting inspections of facilities that have been bombed; and he notes that the agency has no established protocol for inspecting a nuclear site damaged by military attack. Tehran's fear, as he describes it, is practical: that inspectors' findings reach Washington and Jerusalem and guide the next round of strikes.

What happens if the inspectors never get back in?

The first consequence is opacity. Every month without access widens the gap in the agency's knowledge of Iran's stockpile, and every widening gap shortens the warning time the world would have if Tehran chose to build. The Revolutionary Guards say their missile and drone production has already moved underground; a nuclear programme that follows the same path would be harder to track and harder to strike.

The second consequence is imitation. If a state can be bombed as a treaty member and conclude that membership bought it nothing, others will draw the lesson; and the non-proliferation regime, which rests on the promise that compliance brings security, weakens with each such lesson. The hardliners' argument is not only about Iran; it is an argument every state weighing a nuclear option will hear.

Three clocks now running in Tehran

The first clock is diplomatic. The mediators, Qatar and Pakistan, are carrying messages, and Tehran says its two-day plan for the Strait of Hormuz is still on the table. A preliminary deal could unlock limited, phased inspections under the framework of the 2025 Cairo agreement; the Crisis Group's Vaez calls that the most plausible next step.

The second clock is political, and it runs inside Iran. The hardliners have not been answered, and no decision has been announced. The longer the bombed sites stay closed, the stronger their argument grows.

The third clock is military. The Gulf states have just agreed a joint military command in Kuwait, American forces remain in the region, and the threat against the Pickaxe Mountain complex has not been withdrawn. If the talks fail, the next round of strikes, and the next debate about the treaty, will arrive together.
