This posting uses the fine summary of the first week of the 2026 NPT Revue Conference by Ray Acheson in Reaching Critical Will . It pulls together statements made by NPT states on the Iran nuclear conundrum and Iran’s rejoinders and ends with Ray Acheson’s jarring commentary on what was missing in those statements. We shall see what this RevCon comes up with on the NPT nuclear nonproliferation pillar, and on the important NPT pillar of nuclear disarmament.            US asserted that Iran is in violation of Article III of the NPT and its IAEA safeguards agreement.            China said that without the authorisation of the Security Council, launching military strikes against the nuclear facilities of other countries and IAEA safeguards constitutes a serious violation of international law. It noted these actions “ under the pretext of non-proliferation trample on the sovereignt...

     Shortly after the 2026 NPT Review Conference started on April 27, Christopher Yeaw, Assistant Secretary for the U.S. Bureau of Arms Control and Nonproliferation, picked a fight with Iran. My guess is that he chose to do that on his own, without senior level authorization. His intervention prompts me to say to him and the Trump administration, you do want Iran to remain in NPT, don’t you?        The President of the Conference had been chosen in advance to be Ambassador Do Hung Viet of Viet Nam. Thirty-four Vice Presidents were proposed by the Eastern European Group, Western Group and Non-Aligned Group. The Non-Aligned Group selected Algeria and others including Iran.       Yeaw, in a ‘right to reply’, told the conference that it was " indisputable that Iran ‌has long demonstrated its contempt for the ⁠non-proliferation commitments of the NPT, " and had refused to cooperate with the U.N. nuclear watchdog to resolve questions abo...

         Excellent reporting today by Reuters, as always, is the source for this blog.           Trump posted on Truth Social that ‌his envoys would arrive in Islamabad on Monday evening, April 20, for negotiations: " We’re offering a very fair and reasonable DEAL, and I hope they take it because, if they don’t, the United States is going to knock out every single Power Plant, and every single Bridge, in Iran. NO MORE MR. NICE GUY! "            Iran's official IRNA news agency reported that Iran rejected the talks: " Iran stated that its absence from the second round of talks stems from what it called Washington's excessive demands, unrealistic expectations, constant shifts in stance, repeated contradictions, and the ongoing naval blockade, which it considers a breach of the ceasefire. " Iran's chief negotiator, Mohammad Baqer Qalibaf, said the two sides had made progress but were still far apart o...

During the U.S./Israel war on Iran since February 28, it has been rather quiet on the nuclear front. Only a few, limited bombings of the Natanz and Esfahan sites have been reported. Iranian activity at those sites has been limited, as detected through public satellite imagery. Now that U.S.-Iran talks are starting to sound like negotiation of a so-called deal, it is perhaps worthwhile to resume commentary on the Iran nuclear conundrum.            We will start with ‘unpacking’ a statement by IAEA Director General Rafael Grossi on April 15 in South Korea, and a comment by President Donald Trump on April 16.            Rafael Grossi told reporters in Seoul [Apr 15]: “ Iran has a very ambitious, wide nuclear program so all of that will require the presence of IAEA inspectors. Otherwise, you will not have an agreement. You will have an illusion of an agreement. ” He said that any agreement on nuclear technology “ require...

The Iranian regime is talking itself into thinking that war with the U.S. and Israel is their better way forward under present circumstances, and that it is coming soon. Here is what Iran-knowledgeable commentators published on February 21-22.            Ata Mohammed Tabriz’s article in Iran International, Why war may no longer be the worst outcome for Tehran , made these points:            • [C]onfrontation is as civilizational as it is geopolitical. Resistance, even at high cost, is framed as a test of faith in a larger struggle between opposing moral forces.            • Victory, in this view, depends not solely on material advantage but on steadfast adherence to divine principles. Even loss or sacrifice can be reframed as spiritual triumph.            • [D]iplomacy and confrontation carry risks, but only confrontation preserves the possibility o...

IAEA Director General Rafael Grossi made public statements about Iran’s enriched uranium stockpile in an interview with the French TF1 published on February 18, 2026. Here is the relevant part of his interview.            [L]a plupart du matériel que l'Iran avait accumulé jusqu'au mois de juin de l'année dernière, malgré    les bombardements, malgré les attaques, est toujours là, dans la plus grande quantité, où il se trouvait         au moment des attaques. Et donc, il y a une partie qui est peut-être moins accessible, mais le matériel,         est toujours là. Donc, d'un point de vue de non-prolifération, le matériel est toujours là.          { O]n sait exactement où le matériel était stocké. Et si on n'a pas pu accéder aux installations depuis la guerre, on a fait une évaluation assez exacte des dégâts. Et on sait que le matériel était là et qu'il était p rotégé. Do...

Pulling together the massive crisis reporting of the past several days makes it not difficult to see what is going to happen with the U.S. and Iran. Here are summarized highlights.  President Trump  • The President has set some red lines that the Iranians are not yet willing to actually acknowledge.  • Trump on February 13 said that “ regime change ” in Iran “ would be the best thing that could happen .”  • “ The boss is getting fed up…there is 90% chance we see kinetic action in the next few weeks .”  • US president Donald Trump said on February 18 “ Should Iran decide not to make a Deal, it may be necessary for the United States to use Diego Garcia, and the Airfield located in Fairford, in order to eradicate a potential attack by a highly unstable and dangerous Regime — An attack that would potentially be made on the United Kingdom, as well as other friendly Countries. ”  Vice President JD Vance  • US Vice President JD Vance said “ We would very much...

Iran International reported on Jan 28, 2026, that Mohammad Eslami, Iran’s nuclear chief, said on January 28 that if Iran’s nuclear sites have been bombed and destroyed, the IAEA has no grounds to demand continued oversight. He said Iran had not breached its NPT commitments and the IAEA should act strictly within its statutory mandate.          I AEA’s mandate under Iran’s NPT safeguards agreement is to verify the declared nuclear material in the State. The last verification by IAEA before the bombings by Israel started on June 13, 2025, were:            • 441 kg 60%-U235 - most at Fordow, a small amount at above ground facility at Natanz;            • 184 kg 20%-U235 - split between above ground Natanz and Fordow;            • 6,024 kg up to 5%-U235 - around half at Natanz underground, and half at Fordow.            Fo...

Iran International reported on Feb 9 that Iranian Foreign Minister Abbas Araghchi said once again on Sunday, Feb 8: “ Zero enrichment can never be accepted by us .” Put more precisely, Iran’s President Masoud Pezeshkian said on Sunday, Feb 8, that Tehran wanted its rights under the Nuclear Non-Proliferation Treaty (NPT) to be respected.            What are NPT States’ rights under NPT?            Michael Crowley, in the New York Times on Feb 6, 2026, presented the opinion of Gary Samore, Brandeis University, on the issue of Iran’s ‘right’ to enrich Uranium under the NPT:             “ The question hinges on intentionality. If you believe their program is purely peaceful, then they have a legitimate claim to a right to enrich. If you think the Iranian enrichment program is just a  c over to build up to a nuclear weapon option, then they don’t have that right. ”   ...
