THE ATOMIC TERRORIST : ASSESSING THE LIKELIHOOD

Abstract

National security discourse frequently identifies nuclear terrorism as an existential threat, yet an empirical assessment of the technical and logistical requirements suggests the actual likelihood of such an event is vanishingly small. Achieving a successful nuclear detonation requires surmounting a complex series of independent barriers, including the illicit procurement of highly enriched uranium, the recruitment of specialized scientists, and the maintenance of total operational secrecy over a prolonged development period. Historical evidence indicates that sovereign states are unlikely to transfer nuclear assets to non-state proxies due to the risks of detection and catastrophic retaliation. Furthermore, evidence regarding the nuclear ambitions of groups like al-Qaeda often relies on unverified reports or failed scams, while their actual scientific capacity remains rudimentary and insufficient for industrial-scale weaponization. The immense difficulty of machining fissile material and constructing a reliable improvised device distinguishes this threat from conventional terrorist tactics, which utilize simpler, more accessible technologies. Because a successful project requires a perfect cascade of events—from theft and transport to assembly and detonation—the cumulative probability of success is negligible. Consequently, the catastrophic potential of a terrorist atomic strike is decoupled from its statistical probability, which remains near zero when accounting for the exhaustive list of necessary technical achievements. – AI-generated abstract.
