Why did the possibility of terrorist groups acquiring nuclear weapons concern nuclear strategists?

The concern among nuclear strategists regarding terrorist groups acquiring nuclear weapons stems from the threat of "superterrorism." Unlike state actors, who are generally constrained by the logic of deterrence—where the threat of nuclear retaliation prevents aggression—terrorist organizations may not be susceptible to the same traditional strategic calculations.1

Strategists feared that such groups could use nuclear devices to compensate for conventional military inferiority or to execute extreme acts of violence against Western targets. This concern was heightened by the potential for these groups to exploit the "disturbing new threat of chronic weakness" in states with unstable or poorly secured nuclear arsenals, such as those that emerged following the collapse of the Soviet Union.12

Ultimately, the possibility of non-state actors obtaining nuclear material or weapons represents a fundamental shift in asymmetrical warfare, as it introduces an unpredictable element that traditional nuclear policies were not designed to manage. The potential for a deliberate, catastrophic nuclear explosion by an actor outside of established international control systems remains a primary security concern.12
