The United States, joined by the United Arab Emirates and backed by concerns from key European powers, on Monday sharply condemned the United Nations’ decision to give Iran a leading post at a major nuclear treaty conference.
Iran’s selection as one of dozens of vice presidents at the monthlong review conference for the Nuclear Nonproliferation Treaty has reignited criticism over what critics say is a recurring pattern of Iran gaining procedural legitimacy within international institutions despite longstanding concerns about its nuclear behavior.
The clash erupted as the 11th Review Conference of the Nuclear Non-Proliferation Treaty kicked off at UN headquarters in New York, where Iran was selected as one of 34 vice presidents through the Non-Aligned Movement bloc.
The conference includes 191 treaty parties and meets every five years to assess the implementation of the pact aimed at preventing the spread of nuclear weapons.

For the government, the symbolism was immediate and explosive.
“Rather than choosing to use this review conference to defend the integrity of the NPT and hold Iran accountable, we are instead electing Iran as vice president,” Christopher Yeaw, the U.S. assistant secretary for arms control and nonproliferation, told delegates. “It is beyond shameful and a disgrace to the credibility of this conference.”
The UAE and Australia publicly supported the US objection, while Britain, France and Germany also expressed concern, forming a broader coalition than in previous UN disputes, where the US has often been largely alone in challenging Iran’s procedural elevation.

During Monday’s debate, Iranian envoy Reza Najafi dismissed the criticism as “baseless and politically motivated,” accusing the US of hypocrisy and pointing to America’s nuclear history while defending Tehran’s right to peaceful nuclear development. Russia also defended Iran, with Ambassador Andrei Belousov objecting to what he called the politicization of the conference.
“Member States are responsible for the election of other Member States, and they must be accountable for the results of these elections,” Dujarric said.
He added that the UN’s focus remains on the broader nuclear threat and not on the procedural controversy surrounding Iran’s appointment.
“We strongly encourage all Member States participating in the Nuclear Non-Proliferation Treaty Review Conference to focus on what matters most: stopping the spread and threat of nuclear weapons, which remains a global threat,” he said.
Iran’s appointment comes amid increased international concern over Iran’s nuclear trajectory. Western governments and the International Atomic Energy Agency have raised alarm over Iran’s enrichment of uranium to near weapons levels and disputes over inspections, while Tehran insists its program is strictly civilian.
Critics say the controversy exposes a structural contradiction at the heart of the UN system: Geopolitical blocs can elevate states under scrutiny to positions of procedural authority, even at conferences dedicated to the very norms those states are accused of violating.

The last NPT review conference in 2022 failed to produce a consensus document after Russia blocked the agreement. This underlines how deep power differentials have increasingly paralyzed the treaty revision process, according to The Associated Press.
“This is part of a disturbing trend,” Neuer said. “Iran has built up senior positions within the UN system, from human rights bodies to key committees. Each appointment undermines the credibility of international institutions, reinforcing the perception that political deal-making trumps basic norms of behavior.”
