Opening Conflict at the NPT Review Conference
On 27 April 2026 the 11th review conference of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) opened at the United Nations in New York. Iran was elected as one of 34 vice-presidents, a decision that triggered sharp exchanges between United States officials and Iran’s representatives. The dispute unfolded against the backdrop of a two-month armed confrontation between the United States, Israel and Iran.
Background: NPT Process and Iran’s Nuclear Track Record
The NPT entered into force in 1970 and is reviewed every five years. Iran acceded in 1974 and, according to IAEA and U.S. intelligence, operated a nuclear-weapons development programme that was halted in 2003. The 2015 Joint Comprehensive Plan of Action (JCPOA) imposed extensive limits on Iran’s enrichment; the United States withdrew in 2018, after which Tehran gradually exceeded the JCPOA caps, reaching 60 % enrichment by early 2025. The current war began after the U.S. exit from the JCPOA and has intensified scrutiny of Iran’s nuclear activities.
Actors and Official Positions
- United States: Assistant Secretary Christopher Yeaw described Iran’s vice-presidency as “an affront” to the NPT and said Iran has “long demonstrated its contempt for the non-proliferation commitments of the NPT.” A U.S. representative said the administration was “deeply shocked” by the appointment. The U.S. was backed by Australia and the United Arab Emirates; the United Kingdom, France and Germany voiced concern, while Russia objected to singling out Iran.
- Iran: IAEA ambassador Reza Najafi rejected the U.S. remarks as “baseless and politically motivated.” Tehran also disclosed a proposal to suspend discussion of its nuclear programme until the war and Gulf-shipping disputes are resolved.
- White House: Spokeswoman Karoline Leavitt reiterated that President Donald Trump’s “red lines with respect to Iran have been made very, very clear.”
- Conference Chair: Vietnam’s UN ambassador Do Hung Viet noted that Iran was selected by “the group of non-aligned and other states.”
Criticism and Opposition
Analysts highlighted broader concerns about the NPT’s credibility. Sahar Khan argued that “the NPT’s grand bargain has fundamentally broken down because all nuclear-weapon states are modernising their arsenals at an alarming rate, especially China.” Hossein Mousavian warned of “inconsistent enforcement of its principles,” while Rebecca Johnson said the possession of nuclear weapons creates a “sense of impunity.” Russia’s objection to the perceived targeting of Iran and Israel’s non-membership in the treaty, despite its alleged nuclear arsenal, were also cited as points of contention.
Data Snapshot
- 34 vice-presidents elected for the conference.
- Iran’s nomination came from the Non-Aligned Movement, representing 121 developing states.
- The NPT has 191 member states; five are recognized nuclear-weapon states (U.S., Russia, China, U.K., France).
- Iran’s enriched uranium reached 60 % purity by early 2025 (weapons-grade is 90 %).
- The war between the United States, Israel and Iran has lasted roughly two months.
Conflicting Accounts and Gaps
U.S. and IAEA assessments claim Tehran operated a nuclear-weapons program that was halted in 2003, whereas Iran maintains it has never pursued nuclear weapons. Precise figures for Iran’s current stockpile remain undisclosed, and the conference’s final outcomes are still uncertain.

Outlook
The month-long review conference will continue while Iran’s proposal to defer nuclear discussions remains on the table. Diplomatic negotiations are expected to intensify, but the final impact on the NPT’s credibility and the regional security environment remains unresolved.
