Iran: controllo nucleare: tecnicamente possibile, di fatto difficile

Iran’s nuclear program remains a focal point of international concern, as tensions between the country and Western powers continue to shape the landscape of global non-proliferation efforts. Recent developments suggest that while technical feasibility for increased oversight exists, political hurdles persist, complicating the path toward renewed inspections by the International Atomic Energy Agency (IAEA). These challenges underscore the delicate balance between transparency and sovereignty, as well as the broader geopolitical implications of Iran’s nuclear ambitions.

The situation took a potential turning point when IAEA Director-General Rafael Grossi expressed confidence that inspections of Iranian nuclear sites could resume soon. His comments came following the signing of an interim agreement between Iran and the United States, which reportedly outlines provisions for enhanced monitoring. According to Grossi, while the exact timing of such inspections remains uncertain, their resumption is seen as inevitable. “It will happen,” he emphasized, framing the issue more as a matter of logistics than of possibility.

However, the Iranian government has remained cautious, with officials indicating that the decision to allow IAEA inspectors back into the country hinges on the outcome of a final agreement with the U.S. and progress in lifting economic sanctions. Deputy Foreign Minister Kasem Gharibabadi stated that the issue would be addressed only within the context of a comprehensive deal. Similarly, Iran’s ambassador to the United Nations in Geneva reiterated that Tehran had not yet given consent for the return of IAEA personnel, highlighting the nation’s reluctance to cede control over its nuclear facilities.

Despite these diplomatic hesitations, experts argue that the technical infrastructure of Iran’s nuclear program makes extensive monitoring feasible. Radiochemist Georg Steinhauser of the Vienna University of Technology explained that uranium enrichment occurs in large, visible industrial complexes, making covert weapon development highly improbable. He noted that the scale of operations—requiring vast facilities and thousands of centrifuges—makes clandestine production unlikely. Furthermore, the complexity of the enrichment process means that even partial transparency could provide significant insight into Iran’s nuclear activities.

Political scientist Hessam Habibi Doroh of the Institute for Peace Support and Conflict Management (IFK) acknowledged the significance of the interim agreement, calling it a step forward in fostering dialogue and transparency. Yet, he also pointed out that internal resistance within Iran continues to hinder progress. A recent parliamentary law has restricted collaboration with the IAEA, and influential factions within the legislature oppose full-scale inspections. This legislative stance reflects deep-seated concerns among certain segments of the Iranian population regarding national security and sovereignty.

Compounding these challenges is the current state of IAEA oversight. Since the June 2025 attacks on Iranian nuclear facilities, the agency has been unable to conduct direct inspections, relying instead on satellite imagery for surveillance. This limitation has left critical gaps in knowledge regarding Iran’s uranium stockpiles and operational capacity. According to the IAEA, Iran still possesses approximately 440 kilograms of uranium enriched to 60%, a quantity that, if further processed, could potentially yield enough material for multiple nuclear weapons. While Iran denies any intention to develop such arms, the presence of this material raises ongoing questions about the extent of its nuclear capabilities.

The debate over Iran’s nuclear program is further complicated by the broader geopolitical context. The U.S.-Iran relationship remains strained, with historical conflicts and mutual distrust shaping the dynamics of negotiations. Meanwhile, regional actors and international allies continue to monitor developments closely, aware of the potential consequences of unchecked proliferation. For now, the path to renewed inspections appears to depend on resolving the political impasse between Iran and its adversaries, a process that may take months—or perhaps years—to achieve. Until then, the world must contend with uncertainty, as the balance between transparency and secrecy remains precarious.
