Statements by some political circles regarding Iran’s continued membership in the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) have once again brought the issue into the media spotlight, reviving an old but now highly sensitive debate: Given the new security environment and the experience of recent military attacks, should Iran remain within the NPT framework, or could withdrawal from the treaty become part of the country’s new deterrence strategy
The significance of this question extends well beyond a single international treaty. The decision on the NPT is directly linked to three interconnected issues: the security of nuclear facilities and nuclear expertise, the degree of freedom Iran has to develop its nuclear program, and the country’s diplomatic capacity to manage external pressure. Supporters and opponents of withdrawal therefore approach the same fundamental issue from different perspectives: How can Iran’s security and national interests be safeguarded as external pressure intensifies?
The main argument advanced by supporters of withdrawal from the NPT is rooted in the experience of recent years. From this perspective, Iran placed a substantial portion of its nuclear activities within the framework of international commitments and under monitoring, yet these mechanisms failed to prevent political pressure, sanctions or even military attacks on the country’s nuclear facilities. In this view, there has been an insufficient balance between Iran’s commitments and the practical protection it has received from the international system.
Critics of the International Atomic Energy Agency’s () performance focus on this same point. In their view, if NPT membership and safeguards cooperation have failed to guarantee the security of nuclear facilities and the rights of member states, the continuation of this arrangement requires reconsideration. Supporters of withdrawal argue that abandoning the restrictions imposed by the treaty could alter the security calculations of the opposing parties and enable Iran to redefine its relationship with international institutions on a new basis.
Under this approach, withdrawal from the NPT is not necessarily viewed as a move toward building nuclear weapons. Rather, it is presented as a measure to strengthen Iran’s bargaining leverage and redefine its deterrence posture. Article X of the treaty is also relevant from this perspective. It recognizes the right to withdraw under circumstances in which extraordinary events related to the treaty’s subject matter jeopardize a country’s supreme interests, while requiring prior notification and an explanation of the reasons for withdrawal.
Opponents of withdrawal, however, raise a fundamental question in response: Would leaving the NPT necessarily make Iran more secure? Membership in the treaty offers no absolute guarantee against war or external pressure, but withdrawal offers no such guarantee either. In fact, withdrawal could heighten existing concerns about the future of Iran’s nuclear program and pave the way for additional political, economic and security pressures.
From this perspective, one of the most important advantages of remaining in the NPT is that Iran retains the ability to invoke its nuclear rights under a recognized international treaty. As a member, Iran can continue to emphasize its right to the peaceful use of nuclear energy and pursue its disputes with the West within a legal and diplomatic framework. Opponents of withdrawal argue that abandoning this framework could narrow Iran’s diplomatic room for maneuver and make it easier for opposing parties to build a political consensus against Tehran.
At the same time, one important point must not be overlooked in this debate: criticizing the ’s performance and concluding that withdrawal from the NPT is necessary are two different matters. An international institution’s performance may be inadequate or open to criticism, but that does not, in itself, prove that withdrawal from the treaty is the best way to enhance security. Reaching such a conclusion requires an equally thorough examination of the legal, political, economic and security consequences of withdrawal.
Nor is withdrawal from the NPT equivalent to ending all of Iran’s obligations toward the . The legal status of the safeguards agreement, prior commitments and other related arrangements are separate matters that must be examined independently. A decision to withdraw, therefore, is not a simple endpoint; it could instead mark the beginning of a series of decisions and reciprocal responses.
Ultimately, the central issue comes back to the concept of “deterrence.” Supporters of withdrawal believe that remaining in a treaty that has failed to protect the country against security threats may be constraining, and that withdrawal could change the calculations of the opposing parties. Opponents, however, warn that deterrence is not achieved simply by raising the costs for the other side. It is also necessary to assess what new costs a decision would impose on Iran itself and whether it would reduce the likelihood of confrontation or, conversely, increase it.
From this standpoint, the NPT debate should not be reduced to a simplistic choice between “surrender” and “resistance.” Remaining in the treaty could also require a reassessment of how Iran cooperates with the , stronger protection for sensitive information and facilities, and more active use of legal and diplomatic tools. If withdrawal is considered an option, it also requires a clear explanation of what would follow, how major powers might respond, what the economic consequences would be, and how the resulting repercussions would be managed.
Iran’s current challenge is not simply a choice between “staying” and “withdrawing.” The central task is to develop a strategy that balances deterrence, security, nuclear rights and the possibility of diplomacy. The experience of recent years has shown that neither membership in an international treaty nor withdrawal from it can, on its own, guarantee national security. What matters is the set of policies put in place following any decision.
For this reason, the return of the NPT debate to the country’s political discourse can be seen as an opportunity for a more thorough discussion of the future of Iran’s nuclear file—one that neither overlooks the costs of withdrawal nor disregards the experience of past pressure and attacks. A decision with such far-reaching strategic implications requires, above all, a simultaneous assessment of deterrence, diplomatic capacity, economic costs and the likely responses of foreign actors. The central question remains: Which course of action would offer the greatest potential to safeguard Iran’s national interests under the new circumstances without inadvertently drawing the country into another cycle of pressure and tension?
