Assessing the risk of nuclear attack-by-proxy turns on the question of whether a state could sponsor nuclear terrorism and remain anonymous. A leader could rationalize such an attack—and entrust terrorists with a vitally important mission—only if doing so allowed the sponsor to avoid retaliation. After all, if a leader did not care about retaliation, he or she would likely conduct a nuclear strike directly. Giving nuclear weapons to terrorists makes sense only if there is a high likelihood of remaining anonymous after the attack.
