The threat of nuclear terrorism has reached unprecedented levels, according to Mauro Miedico, director of the UN Counter-Terrorism Centre, who warned that technological advances and terrorist recruitment of specialized expertise have fundamentally altered the security landscape in ways that demand immediate international action.
In a UN publication released on Sunday, Miedico outlined how terrorist organizations have deepened their engagement with emerging technologies, recruited AI specialists, and deployed drones in attacks—capabilities that collectively raise the risk that non-state actors could attempt to deploy a dirty bomb or worse. While no nuclear terrorist attack has ever occurred, the structural protections that have prevented such incidents remain fragile and dependent on sustained international commitment.
The Escalating Threat
Miedico emphasized that groups such as Al-Qaeda have explicitly stated their intention to carry out nuclear attacks. The fact that no such incident has materialized thus far reflects not an absence of intent but rather the effectiveness of existing international mechanisms—a distinction that underscores how dependent global security remains on continued vigilance and institutional cooperation.
Prof. Chuck Freilich, former deputy National Security adviser in Israel and adjunct professor at Tel Aviv University and Columbia University, characterized Al-Qaeda's organizational structure and ideology as particularly alarming. He noted that Al-Qaeda's "nihilistic" nature would make it "almost impossible to deter them" from actually using nuclear weapons if they obtained such capabilities. The Combating Terrorism Center has documented that Al-Qaeda's structure has devolved into a dispersed, decentralized network of franchise groups—a fragmentation that complicates attribution and enforcement but does not reduce the threat.
Historical precedent adds weight to these concerns. The UN publication cited instances in which uranium dioxide was stolen and possibly trafficked to countries with high concentrations of the terror group's members, demonstrating that the material precursors for nuclear weapons have already entered illicit supply chains.
The International Response Gap
Miedico identified a critical institutional gap: not all UN Member States are parties to the International Convention for the Suppression of Acts of Nuclear Terrorism (ICSANT). Universal adoption of this treaty represents, in his assessment, a key protection against nuclear terrorism. The incomplete participation of Member States reflects either insufficient political will or inadequate resources devoted to implementing and enforcing the convention—both structural problems that demand remedial action.
Freilich's analysis suggests that the regional dimensions of this threat require differentiated assessment. He characterized the probability of a terrorist nuclear attack on Israel as "very low" but warned that if such an attack were to occur, the consequences would be "extraordinarily high" despite Israel's extensive protective measures. This framing highlights how even low-probability events with catastrophic consequences demand preventive investment.
Deterrence and State Actors
Freilich also addressed the distinct question of state actors and nuclear proliferation. He assessed that Hamas and Hezbollah would be unlikely to create a nuclear incident because of the devastating impact on Palestinian and Lebanese populations—a calculation rooted in rational state interests rather than principled restraint. Yet he characterized the remote possibility as a "severe threat," suggesting that probability-based risk assessment may underestimate the consequences of miscalculation.
On Iran, Freilich judged it "unlikely, although not impossible" that Iran would transfer nuclear weapons or components to regional actors, given the risk of devastating retaliation. He suggested Iran would more likely employ nuclear potential as an "insurance policy" or tool of intimidation rather than as an instrument for actual use. This assessment implies that containment strategies depend on maintaining the credible threat of overwhelming response—a fragile foundation for long-term security.
Why This Matters:
The convergence of dispersed terrorist networks, advancing technology, and incomplete international legal frameworks creates a structural vulnerability in global security architecture. The absence of a nuclear terrorist attack to date reflects institutional design and international cooperation, not the absence of intent or capability among non-state actors. Miedico's warning that universal adherence to ICSANT is essential indicates that current treaty participation falls short of what security experts consider necessary. For populations in regions where terrorist organizations operate or where state actors possess nuclear capabilities, the gap between existing protections and optimal security represents a tangible risk. The stakes are not hypothetical: the material precursors for nuclear weapons have already been stolen and trafficked. From a center-left perspective emphasizing institutional accountability and collective security, the question is whether democratic governments will invest sufficient political capital in achieving universal treaty participation and strengthening the international mechanisms that have, thus far, prevented catastrophe.
