The boss had a sharp observation this week: if nuclear proliferation in the Middle East is dangerous enough to justify bombing another country’s facilities, shouldn’t the region’s only actual nuclear power be part of the treaty designed to prevent exactly that?
Nuclear proliferation in the Middle East is not a hypothetical scenario. It is the defining security crisis of this decade. The region already has one undeclared nuclear arsenal, a freshly bombed nuclear program, a brand-new mutual defense pact with nuclear implications, and a cornerstone treaty that may not survive the year. The question is no longer whether proliferation will happen, but whether anyone still has the tools to stop it.
The Open Secret
Israel has possessed nuclear weapons since the 1960s, yet it has never signed the Treaty on the Non-Proliferation of Nuclear Weapons. It remains one of only four states outside the NPT, alongside India, Pakistan, and South Sudan. Its policy of “nuclear opacityA policy of neither confirming nor denying possession of nuclear weapons, allowing a state to maintain deterrence without the political consequences of declared status.” means it neither acknowledges nor denies the existence of its arsenal.
That arsenal is not small. The Federation of American Scientists and the Stockholm International Peace Research Institute estimate Israel possesses 90 nuclear warheads. The Nuclear Threat Initiative puts the upper range higher, noting Israel has produced enough plutonium and highly enriched uranium for up to 300 weapons. It operates six Dolphin-class submarines believed capable of launching nuclear-armed cruise missilesA guided missile that flies at low altitude using onboard navigation to reach its target with high precision, as opposed to a ballistic missile., and its Jericho III ballistic missilesA rocket-propelled weapon launched on a high arcing trajectory; after its engines burn out, it follows a ballistic (unpowered) path to its target, typically carrying conventional or nuclear warheads over long distances. have a potential range of up to 6,500 kilometers.
Jeffrey Lewis, a nuclear expert at the Middlebury Institute, has a term for this posture: “implausible deniability.”
The Treaty Everyone Else Signed
The NPT entered into force in 1970 with a straightforward bargain: non-nuclear states agreed not to develop weapons, nuclear states agreed to pursue disarmament, and everyone got access to peaceful nuclear technology. Today, 191 states have joined. It is the most widely adhered-to arms control agreement in history.
In 1995, the treaty was extended indefinitely. A key part of the deal was a resolution calling for a weapons-of-mass-destruction-free zone in the Middle East. That resolution was “crucial to securing the indefinite extension of the NPT,” according to the Center for Arms Control and Non-Proliferation. Thirty-one years later, the zone does not exist.
The idea of a Middle East WMD-free zone was first proposed in 1974 by Iran and Egypt. The UN General Assembly endorsed it. The Security Council endorsed it. NPT review conferences repeatedly endorsed it. In 2010, the review conference called for a conference to bring all Middle Eastern states together to discuss the zone. The United States formally cancelled that conference in November 2012 because Israel was unwilling to attend.
Nuclear Proliferation in the Middle East: Bombs for Non-Proliferation
Israel’s approach to nuclear threats in its neighborhood has been consistent: destroy them by force. In 1981, it bombed Iraq’s Osirak reactor. In 2007, it struck a suspected nuclear facility in Syria. In June 2025, it launched strikes against Iran’s nuclear facilities and assassinated nuclear scientists, with the United States joining days later to hit Fordow, Isfahan, and Natanz.
This is known as the Begin DoctrineIsrael's declared policy of conducting preventive military strikes against any regional state developing weapons of mass destruction, regardless of that state's treaty obligations.. Prime Minister Begin explicitly stated that preventive strikes are “not an anomaly, but a precedent for every future government in Israel,” regardless of whether target countries are NPT members or their facilities are under IAEA safeguards.
The logic is clear: Israel considers nuclear proliferation in the Middle East an existential threat worth going to war over. The contradiction is equally clear: the state most willing to use force against proliferation is the only nuclear-armed state in the region, and the only one that refuses to submit to the international framework designed to prevent it.
What the Bombs Broke
The June 2025 strikes did damage Iran’s nuclear program. The Pentagon estimated a setback of “one to two years at least.” But they also broke something else: the inspection regime.
In July 2025, Iran’s President Pezeshkian signed a law suspending cooperation with the IAEA. Inspectors were barred from visiting nuclear sites without approval from Iran’s Supreme National Security Council. Efforts to resume inspections have since stalled. As of early 2026, the IAEA has been unable to verify Iran’s stockpile of highly enriched uranium or access key sites targeted in the war.
Iran’s foreign minister dismissed the IAEA chief’s requests to visit bombed sites as “meaningless and possibly even malign in intent.” Iran’s parliament has begun preparing documents to leave the NPT entirely.
In other words: the war meant to prevent proliferation may have made verification impossible.
The Saudi Equation
In September 2025, Saudi Arabia and Pakistan signed a Strategic Mutual Defense Agreement stipulating that any aggression against one would be considered aggression against both. Pakistan’s Defense Minister Khawaja Mohammad Asif told GeoTV that Pakistan’s nuclear weapons capabilities “will be made available” to Saudi Arabia under the agreement. He later walked the statement back, but the ambiguity was the point.
This was the first time a nuclear-armed state outside the NPT has made an extended nuclear deterrenceA commitment by a nuclear-armed state to use its nuclear weapons in defense of an allied non-nuclear state, extending its deterrence umbrella beyond its own borders. commitment to another state. Saudi Arabia, a non-nuclear NPT signatory, is prohibited from developing its own weapons. But it does not need to build a bomb if it can borrow one.
The Bulletin of the Atomic Scientists reported that Saudi Arabia was “believed to have been instrumental in financing Pakistan’s nuclear weapons program,” reportedly providing annual grants of $1 billion toward what became known as the “Sunni bomb.” Washington was reportedly informed of the defense agreement only after it was signed.
The Escalation Everyone Can See
In March 2026, Iran struck the Israeli towns of Dimona and Arad with ballistic missiles, injuring more than 180 people. Iranian state media framed the strikes as retaliation for an attack on its Natanz enrichment site. Dimona is home to Israel’s main nuclear reactor and research facility. The IAEA confirmed no abnormal radiation levels were detected, but the symbolism was unmistakable: both sides are now targeting each other’s nuclear infrastructure.
As one strategic assessment in JURIST noted, “in time, Saudi Arabia, Egypt or even non-Arab Turkey could decide to ‘go nuclear.'” The region is moving toward a future where multiple states either possess nuclear weapons or shelter under someone else’s umbrella, while the treaty meant to prevent this outcome crumbles.
The Double Standard
Israel’s nuclear arsenal exists almost entirely outside international regulation. It has not signed the NPT. It has not ratified the Comprehensive Test Ban Treaty. It has not signed the Biological Weapons Convention and has signed but not ratified the Chemical Weapons Convention. Its nuclear facilities are not subject to standard IAEA inspection regimes.
Meanwhile, it insists that Iran’s nuclear program is an existential threat requiring military action, and the United States backs that position with cruise missiles.
This is not a fringe observation. The Center for Arms Control and Non-Proliferation calls Israel’s nuclear ambiguity “a key obstacle to establishing a weapons of mass destruction free zone in the Middle East.” Every NPT review conference since 1995 has returned to the unfulfilled promise of a WMD-free zone. Every time, Israel’s refusal to participate has blocked progress.
The 2026 NPT Review Conference opens in New York on April 27. It arrives in a landscape where New START is set to expire, Iran has suspended IAEA cooperation, Saudi Arabia has a nuclear patron, and the Begin Doctrine has been applied with American support. The treaty that has held since 1970 may not survive a world where proliferation is punished by bombs from the one state that refuses to play by the rules.
The question for diplomats gathering in New York next month is simple. You cannot credibly ask every nation in the Middle East to forswear nuclear weapons while the most powerful military in the region keeps 90 warheads in the basement and refuses to even acknowledge they exist.
The boss flagged an uncomfortable symmetry this week, and it deserves unpacking: if nuclear proliferation in the Middle East is sufficiently threatening to justify kinetic action against sovereign states, the region’s sole nuclear-armed power probably ought to be inside the regime it claims to defend.
Nuclear proliferation in the Middle East has moved from a nonproliferation textbook scenario to an active, multi-front crisis. The region hosts one undeclared nuclear arsenal, a nuclear program degraded by airstrikes but now outside verification, a mutual defense pact with explicit nuclear overtones, and a cornerstone treaty approaching what may be its terminal review conference. The analytical challenge is no longer modeling proliferation risk. It is assessing whether any institutional framework remains capable of managing it.
Israel’s Nuclear Posture: Opacity as Strategy
Israel has maintained nuclear weapons since the 1960s under a policy scholars distinguish as “nuclear opacityA policy of neither confirming nor denying possession of nuclear weapons, allowing a state to maintain deterrence without the political consequences of declared status.,” a framework formalized through a tacit 1969 understanding with the Nixon administration. Israel committed “not to be the first to introduce nuclear weapons into the Near East,” a formulation it interprets narrowly to mean it will not conduct a test or make an official declaration.
The arsenal’s scale is debated but converges around consistent estimates. The Federation of American Scientists and SIPRI estimate 90 warheads. The Nuclear Threat Initiative notes Israel has produced enough fissileDescribes materials like uranium-235 or plutonium-239 that can sustain a nuclear chain reaction when struck by slow (thermal) neutrons. material for up to 300 weapons, with delivery systems including Jericho III IRBMs (range: 4,800 to 6,500 km) and six Dolphin-class submarines believed capable of launching nuclear-armed cruise missilesA guided missile that flies at low altitude using onboard navigation to reach its target with high precision, as opposed to a ballistic missile..
Jeffrey Lewis of the Middlebury Institute describes the current posture as “implausible deniability” rather than genuine ambiguity. The Nuclear Weapons Ban Monitor confirms Israel is non-party to the NPT, the CTBT (signed but not ratified), the BWC, and the CWC (signed but not ratified). Its nuclear facilities operate under an item-specific IAEA agreement rather than a comprehensive safeguards agreement.
The strategic logic is straightforward. Opacity allows Israel to maintain a deterrent without triggering the political and legal consequences of declared possession: NPT withdrawal demands, sanctions pressure, or regional arms races formally attributed to its arsenal. The cost is borne by the nonproliferation regime itself.
The NPT’s 1995 Bargain and Its Collapse
The NPT, which entered into force in 1970, now has 191 states parties. Its indefinite extension in 1995 was secured through a package that included a resolution calling for a Middle East Weapons-of-Mass-Destruction-Free Zone (MEWMDFZ). The Center for Arms Control and Non-Proliferation has described this resolution as “crucial to securing the indefinite extension of the NPT.”
The MEWMDFZ concept predates the extension by two decades. It was proposed in 1974 by Iran and Egypt, endorsed by the UN General Assembly, and repeatedly affirmed by NPT review conferences. The 2010 review conference called for a conference of all Middle Eastern states to discuss its establishment. The United States formally cancelled that conference in November 2012 after Israel refused to attend.
The structural problem is fundamental. The NPT’s three pillars (non-proliferation, disarmament, and peaceful use) require reciprocity. Non-nuclear states accept inspections and forgo weapons; nuclear states accept disarmament obligations. Israel exists entirely outside this framework while actively using military force to enforce non-proliferation on others. This asymmetry has fueled non-nuclear states’ anger at nuclear-armed states for failing to meet their Article VI disarmament obligations, contributing to the failure of consecutive review conferences to produce consensus outcomes.
Nuclear Proliferation in the Middle East: The Begin DoctrineIsrael's declared policy of conducting preventive military strikes against any regional state developing weapons of mass destruction, regardless of that state's treaty obligations. and Its Consequences
Israel’s approach to regional proliferation has followed a consistent operational template. In 1981, it bombed Iraq’s Osirak reactor. In 2007, it struck a suspected facility at Deir Ezzor in Syria. In June 2025, it launched a 12-day campaign against Iran’s nuclear infrastructure, with the United States striking Fordow, Isfahan, and Natanz.
Begin explicitly stated that preventive strikes constitute “a precedent for every future government in Israel,” regardless of target states’ NPT membership or IAEA safeguards compliance. The European Leadership Network’s Tarja Cronberg frames this as “the militarisation of non-proliferation,” noting that these actions “are illegal both according to the UN Charter and international law” and that “there is no legitimacy for military action by an individual state” based on assumed nuclear intentions.
The June 2025 strikes produced a mixed strategic outcome. The Pentagon estimated Iran’s nuclear program was set back “one to two years at least.” But the strikes triggered Iran’s suspension of IAEA cooperation, expulsion of inspectors, and parliamentary preparations to withdraw from the NPT. Efforts to resume inspections have since stalled. As of early 2026, the IAEA cannot verify Iran’s enriched uranium stockpile or access key targeted sites.
The nonproliferation cost may exceed the proliferation benefit. As Cronberg observes, “destroying nuclear facilities and killing scientists not only undermines permanent peaceful solutions to prevent proliferation in the Middle East but also creates further proliferation risks.”
The Saudi-Pakistan Nuclear Nexus
On September 18, 2025, Saudi Arabia and Pakistan signed a Strategic Mutual Defense Agreement during Pakistani Prime Minister Shahbaz Sharif’s visit to Riyadh. The pact stipulates that “any aggression against either country shall be considered an aggression against both.”
The nuclear dimension is deliberately ambiguous. Pakistani Defense Minister Khawaja Mohammad Asif told GeoTV that Pakistan’s nuclear weapons capabilities “will be made available” to Saudi Arabia. He subsequently retracted the statement. A Saudi analyst described by AFP as having government ties stated that “nuclear [deterrence] is integral” to the deal. The Arms Control Association noted this is “the first time that a state with nuclear weapons outside of the nuclear Nonproliferation Treaty has made an extended nuclear deterrenceA commitment by a nuclear-armed state to use its nuclear weapons in defense of an allied non-nuclear state, extending its deterrence umbrella beyond its own borders. commitment to another state.”
The historical context deepens the concern. The Bulletin of the Atomic Scientists reports that Saudi Arabia was “believed to have been instrumental in financing Pakistan’s nuclear weapons program,” with annual grants reportedly reaching $1 billion toward what became known as the “Sunni bomb.” The Bulletin’s analysis frames the pact as driven by “a mounting perception that the United States had abandoned the region” and Israel’s “growing hegemonyThe dominance or supremacy of one nation, group, or system over others. In economics, it refers to control over global systems or markets..”
Washington was reportedly informed only after the agreement was signed. The strategic implication is that extended deterrence, previously a monopoly of the P5 nuclear states and their alliance structures, has now entered a region where no equivalent command-and-control architecture, crisis communication channels, or escalation management protocols exist.
The March 2026 Escalation
On March 21, 2026, Iran struck the Israeli towns of Dimona and Arad with ballistic missilesA rocket-propelled weapon launched on a high arcing trajectory; after its engines burn out, it follows a ballistic (unpowered) path to its target, typically carrying conventional or nuclear warheads over long distances., injuring more than 180 people. Iranian state media described the strikes as retaliation for an attack on Natanz. Dimona hosts the Shimon Peres Negev Nuclear Research Center, Israel’s primary nuclear facility. The IAEA confirmed no abnormal radiation levels, but Israeli air defenses failed to intercept the missiles.
Both sides are now conducting tit-for-tat strikes against nuclear infrastructure. This crosses a threshold that Cold War deterrence theory specifically sought to avoid: direct attacks on nuclear facilities during active hostilities, with the attendant risk of radiological release, miscalculation, or escalatory pressure toward nuclear use.
The “Samson OptionThe concept that Israel would resort to massive nuclear retaliation, including strikes on adversaries' capitals, as a last-resort deterrent if facing existential defeat.”, the concept that Israel could resort to nuclear weapons if faced with existential defeat, has moved from academic literature into operational relevance. As Ahmed Najar writes in Al Jazeera, “the more a state interprets its wars as existential, the lower the psychological barrier to extreme escalation becomes.”
The 2026 Review Conference
The 2026 NPT Review Conference opens in New York on April 27. It convenes amid the potential expiration of New START, Iran’s suspension of IAEA cooperation and potential NPT withdrawal, the Saudi-Pakistan extended deterrence precedent, and active military strikes against nuclear facilities by a non-NPT state.
The JURIST assessment captures the core dilemma: “in time, Saudi Arabia, Egypt or even non-Arab Turkey could decide to ‘go nuclear.'” The NPT cannot credibly demand non-proliferation compliance from regional states while the region’s sole nuclear-armed power operates entirely outside its framework, uses military force to enforce compliance on others, and sabotages every diplomatic initiative toward a WMD-free zone.
The European Leadership Network’s analysis is blunt: “the militarisation of non-proliferation pushes the Nuclear Non-Proliferation Treaty into the margins.” The arena, Cronberg writes, is now “free for any claims that a state has intentions to access nuclear weapons and, consequently, justifies military action against it, paving the way for regime changeThe deliberate replacement of a government through military, diplomatic, or economic intervention, typically by external actors..”
The path forward requires confronting the contradiction at the center of Middle Eastern nonproliferation. A treaty regime that tolerates one undeclared nuclear arsenal while authorizing airstrikes against another state’s program is not a nonproliferation regime. It is a hierarchy enforced by bombs. Until that changes, every state in the region has a rational incentive to seek its own deterrent, and the diplomats gathering in New York next month will be rearranging chairs on a sinking ship.
