A U.S.-Iran flare-up and Israeli strikes have shadowed the NPT review conference in New York. The five-year meeting brings together all 191 parties to the Treaty on the Non‑Proliferation of Nuclear Weapons to assess compliance and progress. Delegates are focused on how much enriched uranium Iran holds, claims of “zero accumulation,” and whether the International Atomic Energy Agency (IAEA) can carry out full verification. Omani Foreign Minister Badr Albusaidi said Iran agreed on Feb. 27 to downblend and convert material — but U.S. and Israeli strikes hours later deepened doubts about implementing those pledges.

Summit opens under a cloud

The NPT review conference began in New York as diplomats confronted the fallout from a brief US–Iran confrontation that involved Israeli strikes, a fragile ceasefire and competing claims about Tehran’s fissile material. The conference is the treaty’s main forum for checking whether signatories are keeping their side of the bargain: non-nuclear states agree not to acquire weapons while recognised nuclear powers accept commitments toward disarmament and share peaceful nuclear technology under IAEA supervision.

At the heart of the talks is a technical question with wide political weight: how much enriched uranium Iran holds, where it is stored and what will happen to it. Those details determine whether verification can be complete and whether any mediated agreement can be durable.

What was promised — and what happened next

On Feb. 27, Omani Foreign Minister Badr Albusaidi — a mediator between Washington and Tehran — said Iran had agreed to “zero accumulation,” “zero stockpiling,” and full IAEA verification of its existing inventory, with material to be downblended and converted into fuel. Hours after that announcement, the United States and Israel carried out strikes, leaving delegates to ask whether technical concessions can survive battlefield actions and whether verification arrangements can proceed when military strikes are possible.

The episode has reopened old fault lines. The U.S. withdrew from the 2015 Iran nuclear accord in 2018. Israel, widely reported to possess nuclear weapons but never officially acknowledging them, is not a party to the NPT. Those facts feed accusations of double standards at the summit and widen the gap between disarmament commitments and practice.

The treaty’s strains and where they show up

The NPT rests on three pillars: nonproliferation, disarmament and peaceful nuclear cooperation under IAEA oversight. While the peaceful-use pillar has largely held up, disarmament has not kept pace with expectations.

  • Many delegations say modernisation programs by recognised nuclear powers weaken the treaty’s moral authority.
  • Perceptions that the rules are applied unevenly make nonproliferation agreements harder to sell domestically and internationally.
  • Verification of contentious cases, such as Iran’s stockpile, becomes politically fraught when military action intervenes.

"The NPT’s grand bargain has fundamentally broken down because all nuclear-weapon states are modernising their arsenals at an alarming rate, especially China," said Sahar Khan, a Washington, DC–based independent analyst and nonresident fellow at the Institute for Global Affairs. That concern was a recurring theme among delegations: modernisation programs by recognised nuclear powers weaken the moral authority of the treaty’s disarmament promise.

How the US is affected politically

The United States sits squarely in the middle of the dispute, balancing nonproliferation aims, regional security concerns and the diplomatic task of sustaining verification arrangements amid renewed military tension.
