The Nuclear Tipping Point, Iran’s Parliament Mulls Exit from NPT as War Escalates
As Tehran Questions the Benefits of a Treaty That Does Not Protect Its Facilities from Attack, the World Faces the Prospect of a Nuclear-Armed Iran—or a Regional Arms Race
Iran’s Parliament is reviewing a possible exit from the Nuclear Non-Proliferation Treaty (NPT), Foreign Ministry spokesperson Esmail Baghaei said on Monday, while insisting that Tehran has not and will not seek nuclear weapons. “What is the benefit of joining a treaty in which bullying parties at the international level not only do not allow us to benefit from its rights but also attack our nuclear facilities?” Mr. Baghaei said, adding that Tehran would respect the treaty as long as it is a member.
The statement is not a declaration of withdrawal. It is a warning—a signal that Iran’s patience with the international order is wearing thin. For decades, Iran has insisted that its nuclear programme is for peaceful purposes and that as a signatory of the NPT, it has the right to peaceful nuclear enrichment. But the NPT has not protected its facilities from attack. In June 2025, the US and Israel attacked Iran’s key nuclear facilities. In the ongoing war, Israel has targeted Iran’s nuclear facilities again. If the treaty does not provide security, why remain a party to it?
The NPT: A Contract Broken
The Nuclear Non-Proliferation Treaty is the cornerstone of the global nuclear order. It has three pillars: non-proliferation, disarmament, and the peaceful use of nuclear energy. States without nuclear weapons commit not to acquire them; states with nuclear weapons commit to disarmament; and all states have the right to develop peaceful nuclear energy.
Iran has been a party to the NPT since 1970. It has consistently argued that its nuclear programme falls under the third pillar—the peaceful use of nuclear energy. It has allowed International Atomic Energy Agency (IAEA) inspectors access to its facilities. It has signed the Additional Protocol, allowing more intrusive inspections. It has negotiated agreements—the JCPOA—to limit its enrichment in exchange for sanctions relief.
But the US withdrew from the JCPOA in 2018. It reimposed sanctions. It has now attacked Iran’s nuclear facilities. Israel has attacked them repeatedly. From Iran’s perspective, the NPT has not delivered what it promised: the right to peaceful nuclear energy, free from attack. If the treaty cannot protect its facilities, why should it constrain its programme?
The Domestic Debate
“Regarding membership in this treaty, regardless of our clear position on the prohibition of all weapons of mass destruction, this is genuinely a debate taking place within public opinion and at the parliamentary level,” Mr. Baghaei said. The debate is real. There are factions within Iran that have long argued that the country should develop nuclear weapons as a deterrent. The attacks on its facilities have given those factions new ammunition.
The argument is straightforward: if the US and Israel are willing to attack Iran’s nuclear facilities, they must believe that Iran is close to a weapon, or that its programme is so advanced that it poses a threat. If that is the case, then perhaps Iran should actually develop a weapon. The logic of deterrence is brutal but compelling: states that have nuclear weapons are rarely attacked; states that do not are often attacked.
The debate is not settled. There are also factions within Iran that believe acquiring nuclear weapons would be counterproductive—that it would trigger a regional arms race, invite further sanctions, and isolate Iran even more. But the attacks have shifted the balance. The question is no longer whether Iran should have nuclear weapons. The question is whether it can afford not to.
The Strategic Context
The timing of this debate is not coincidental. The US and Israel are at war with Iran. The Strait of Hormuz is closed. Oil prices are soaring. And now, Iran is signalling that it may reconsider its commitment to the NPT.
The threat of withdrawal is a bargaining chip. Iran wants the US to stop the attacks. It wants the Strait reopened. It wants sanctions relief. It wants recognition of its rights under the NPT. By threatening to leave the treaty, it is raising the stakes. If the US wants to prevent a nuclear-armed Iran, it may have to offer concessions.
But the threat also carries risks. If Iran does withdraw from the NPT, it would be a seismic event. The treaty has been remarkably successful in limiting the spread of nuclear weapons. Only four states have developed nuclear weapons outside the NPT framework: India, Pakistan, Israel, and North Korea. North Korea withdrew from the NPT in 2003. If Iran were to follow, it would be a major blow to the non-proliferation regime.
The Response from the West
The Western response to Iran’s signals has been muted. The US is focused on the immediate military campaign. European powers, which were instrumental in negotiating the JCPOA, have been sidelined. The IAEA has not commented. The UN Security Council is paralysed.
This silence may be strategic. The US does not want to escalate the nuclear dimension of the conflict while it is already fighting a war. It may hope that the threat of withdrawal is a bluff, or that it can be resolved through the backchannel negotiations that are reportedly taking place.
But silence also signals weakness. If Iran believes that the West will not respond to a withdrawal, it may be more likely to go through with it. The calculation is complex. Iran does not want to be isolated. It does not want to trigger a regional arms race. But it also does not want to be attacked without a credible deterrent.
The Regional Implications
If Iran were to develop nuclear weapons, the implications for the region would be profound. Saudi Arabia has repeatedly stated that it would seek nuclear weapons if Iran developed them. Turkey has the capacity to develop nuclear weapons. Egypt has the resources. The Gulf states would feel compelled to respond.
A nuclear-armed Middle East is a nightmare scenario. The region is already unstable, with multiple conflicts and deep sectarian divisions. The introduction of nuclear weapons would raise the stakes of every conflict. A miscalculation could lead to nuclear war.
Israel, which already has nuclear weapons, would be particularly threatened. Iran has repeatedly called for Israel’s destruction. A nuclear-armed Iran would pose an existential threat to Israel. The Israeli response would be unpredictable, but it would likely be aggressive. Pre-emptive strikes, covert operations, and a massive military buildup are all possibilities.
The Death of a Commander
In a related development, Iran confirmed on Monday that an Israeli strike had killed the commander of the naval force of the Revolutionary Guards, who Israel had said was responsible for the blocking of the Strait of Hormuz. Alireza Tangsiri “succumbed to severe injuries,” Iran said.
The killing of a senior commander is a significant escalation. It demonstrates Israel’s ability to target high-value Iranian assets. It also gives Iran a reason to retaliate. The cycle of violence continues.
The Path Forward
The debate in Iran’s Parliament over the NPT is a symptom of a deeper crisis. The war has shattered the assumptions that underpinned Iran’s nuclear policy. The NPT was supposed to provide security; it has not. Diplomacy was supposed to resolve disputes; it has failed. The only thing that seems to work is deterrence.
Iran may not withdraw from the NPT. It may use the threat to extract concessions. It may decide that the costs of withdrawal outweigh the benefits. But the fact that the debate is happening at all is a warning. The nuclear order that has held for five decades is fraying. And the war in West Asia is accelerating the process.
The US and Israel have a choice. They can continue their military campaign, risking that Iran will respond by leaving the NPT and developing nuclear weapons. Or they can seek a diplomatic off-ramp, reopening the Strait of Hormuz, halting the attacks, and negotiating a new agreement.
The clock is ticking. The April 6 deadline for the reopening of the Strait is approaching. Iran’s Parliament is debating withdrawal. The war continues. The world is watching.
Q&A: Unpacking Iran’s NPT Debate
Q1: What is Iran’s Parliament reviewing regarding the Nuclear Non-Proliferation Treaty?
A: Iran’s Parliament is reviewing a possible exit from the NPT. Foreign Ministry spokesperson Esmail Baghaei stated that Tehran is questioning the benefit of remaining in a treaty when “bullying parties” not only prevent it from benefiting from its rights but also attack its nuclear facilities. He added that Tehran would respect the treaty as long as it is a member, but the debate is taking place within public opinion and at the parliamentary level.
Q2: Why is Iran reconsidering its NPT membership now?
A: The timing is directly linked to the ongoing war. In June 2025, the US and Israel attacked Iran’s key nuclear facilities, and Israel has continued targeting them in the current conflict. Iran has long argued that as an NPT signatory, it has the right to peaceful nuclear enrichment. From Iran’s perspective, the treaty has failed to protect its facilities from attack, undermining the rationale for continued membership.
Q3: What are the three pillars of the NPT, and how does Iran’s position relate to them?
A: The NPT has three pillars: non-proliferation (states without nuclear weapons commit not to acquire them); disarmament (states with nuclear weapons commit to disarm); and peaceful use of nuclear energy (all states have the right to develop peaceful nuclear energy). Iran has consistently argued its nuclear programme falls under the third pillar. It has allowed IAEA inspections, signed the Additional Protocol, and negotiated the JCPOA. However, US withdrawal from the JCPOA, reimposition of sanctions, and attacks on its facilities have undermined the benefits of participation.
Q4: What are the regional implications if Iran withdraws from the NPT?
A: Withdrawal would be a seismic event. Saudi Arabia has stated it would seek nuclear weapons if Iran developed them. Turkey, Egypt, and Gulf states would likely feel compelled to respond, triggering a regional arms race. Israel, which already has nuclear weapons, would face an existential threat from a nuclear-armed Iran. The Middle East is already unstable; nuclear weapons would raise the stakes of every conflict, and miscalculation could lead to nuclear war. Only four states have developed nuclear weapons outside the NPT framework: India, Pakistan, Israel, and North Korea (which withdrew in 2003).
Q5: What recent military developments have occurred alongside the NPT debate?
A: Iran confirmed that an Israeli strike killed Alireza Tangsiri, commander of the naval force of the Revolutionary Guards, who Israel had said was responsible for blocking the Strait of Hormuz. Israel claimed to have struck weapons production sites in Iran, while Iran’s Revolutionary Guard fired attacks targeting Israel and American bases. The killing of a senior commander represents a significant escalation and demonstrates Israel’s ability to target high-value Iranian assets. The war continues while the nuclear debate unfolds. The US has set an April 6 deadline for Iran to reopen the Strait of Hormuz, threatening further strikes if it does not comply.
