One Day To Go: Deciphering the New NPT Draft Outcome Document (Rev. 3)

Today, the 21st May, as the 2026 NPT Review Conference entered its final 48 hours, President Do Hung Viet circulated a new draft outcome document for consideration (NPT/CONF.2026/CRP.2/Rev.3).

This represents the fourth major text iteration presented to delegations during this gruelling four-week review conference, following Draft Zero, Rev. 1, and Rev. 2. Since plenary sessions were closed, this text is our first public look at the compromises the President thinks are possible to help all parties agree on a final outcome document.

In this brief analysis, I take a quick look at Rev. 3 to make sense of the changes, how they might land with delegations, and what they mean for the final hours of the conference.

Structure, Tone, and Framing

Structurally, Rev. 3 is a significantly more condensed and streamlined document. It contains 45 operative paragraphs and just 7 preambular clauses; a significant reduction from the 93 operative and 19 preambular paragraphs of Rev. 2.

To achieve this, the President has considerably pruned the text. He consolidated several key themes across the preamble and the operative sections, and deleted long, highly detailed lists of international conventions and initiatives.

More importantly, the diplomatic framing has shifted into a slightly more assertive voice. Whereas previous versions read like a “declaration” focusing on abstract principles, Rev. 3 is framed as an action-oriented “decision” document. Ahead of the start of the operative paragraphs, the text now reads:

Consistent with Article VIII.3 of the Treaty, as well as paragraph 7 of Decision I of the 1995 Review and Extension Conference, States parties to the Treaty decide to: . . .

By invoking the 1995 Extension Conference decisions, the President is attempting to give the final document a much firmer procedural standing.

The Bilateral Arms Control Void (US-Russia)

In a major departure from Rev. 2, the new draft deletes all references to the New START treaty and bilateral US-Russia arms control frameworks. Rev. 2 contained explicit language regretting the suspension of New START and calling on the United States and the Russian Federation to voluntarily maintain its strategic limits.

Throughout this conference, the US has repeatedly taken the position that the bilateral arms control framework is no longer relevant in its current format. Conversely, Russia, China, and most non-nuclear-weapon states (NNWS) maintain that the two largest nuclear possessors hold a unique and primary responsibility to engage in bilateral reductions.

By removing these references entirely, the President has bypassed a major point of friction for Washington. However, this deletion will disappoint the NNWS majority, who view the bilateral collapse as a significant setback for global disarmament efforts.

Soft on Risk Reduction

The language on nuclear risk reduction has been noticeably softened, qualified, and stripped of much of the operational detail that was present in earlier drafts.

Where Rev. 2 urged Nuclear-Weapon States (NWS) to “agree to measures necessary to prevent nuclear war” and explicitly listed concrete steps like maintaining the “lowest feasible levels of alert” and establishing “notification and data exchange agreements,” Rev. 3 walks this back. The N5 are now merely called upon to “explore voluntary measures” to reduce strategic risks, accompanied by a new qualifying clause noting that “there are no one-size-fits-all measures.”

This softening will likely disappoint the coalition of middle powers, spearheaded by Switzerland and others, that has spent this conference pushing for a standardised, robust risk-reduction framework.

As a rhetorical offset, however, the iconic consensus statement, “a nuclear war cannot be won and must never be fought”, has been elevated from the preamble of Rev. 2 to the highly visible operative paragraph 1 of Rev. 3.

AI and Human Control

Rev. 3 removes all explicit language concerning “human control” over nuclear weapon systems. Rev. 2 had called for the “full and effective maintenance at all times of human control” and sought risk mitigation regarding Artificial Intelligence. In the new draft, this is replaced by a single, generic reference to “discussions on risks and benefits associated with emerging technologies” within a broader list of risk-reduction topics.

This roll-back will ease immediate objections from states reluctant to commit to binding constraints on military AI, but it represents a clear setback for states seeking to address the intersection of AI and strategic decision-making.

Walking the Ukraine Tightrope

Rev. 3 drops the broad paragraph expressing “grave concern” about the safety and security of civilian nuclear facilities in Ukraine. The inclusion of Ukraine-specific language was the primary reason Russia objected to the final outcome document in 2022. While deleting this paragraph will satisfy Moscow, it is a bitter pill for Ukraine and its European partners.

Nonetheless, the draft does retain a separate, highly specific paragraph (Paragraph 36) recalling the importance of the IAEA Director General’s Five Concrete Principles for securing the Zaporizhzhia Nuclear Power Plant. By focusing purely on the IAEA’s technical principles, the draft tries to walk a thin, technical line on a politically sensitive issue.

A Shift in Tone on Iran

The treatment of Iran’s nuclear activities has undergone a notable shift in tone.

Rev. 3 completely removes the diplomatic framing of Rev. 2, which supported a “diplomatic solution” and highlighted the need for cooperation regarding “undeclared nuclear material.” Instead, the text (Paragraph 16) features new language:

...and emphasize, in this context, that Iran can never seek, develop or acquire any nuclear weapons.

This direct assertion is much tougher in tone than previous drafts, but it stops short of the explicit, punitive condemnation demanded by some Western and Gulf delegations. It represents a delicate middle ground designed to register a firm non-proliferation baseline without completely alienating Tehran and its partners.

The Strengthened Review Process

While many of these changes seem designed to neutralise the possible objections of the nuclear-armed powers, the section on The Strengthened Review Process presents a substantial new proposition designed to appeal to non-nuclear-weapon states.

Rev. 3 uses a formal “decide” to mandate structured, in-person, and interactive discussions in a plenary setting, dedicating one session to each of the five NWS during Review Conferences to scrutinise their national reports. Crucially, it introduces an innovative procedural mechanism: the UN Office for Disarmament Affairs (UNODA) will collect and circulate advance questions from States Parties to guide these sessions.

This is the most concrete, action-oriented element in the entire draft. It aims to institutionalise a mechanism that the N5 have collectively been reluctant to sign up to.

What Next?

The President presented this draft as his “best effort” to bridge deep political divides and achieve a consensus outcome. In his remarks, he urged delegations not to attempt to reopen or “improve” the text, confirming that there would be no paragraph-by-paragraph reading in the plenary.

However, by indicating that his door remains open for private consultations, President Viet has left a narrow window for last-minute adjustments.

The critical question now is whether this draft can garner the necessary critical mass of support for its key bargains. Or whether opening up elements of it for amendment will disrupt its core trade-offs.

The answer will become clear during tomorrow’s plenary session where the fate of the 2026 Review Conference will be decided.
