The books under review reveal considerable agreement about suicide bombers. Yet there is a significant gap between the scholarly consensus they embody and widespread perceptions about the subject. We learn, for example, that suicide missions are as old as the hills. We learn that there is no particular link between the propensity to engage in suicide attacks or other forms of extreme terrorism and religious belief—let alone belief in Islamic fundamentalism. We learn that Sri Lanka's secular Marxist Tamil Tigers have been responsible for more suicide attacks than any other group in recent decades. We learn that even within Islamist groups like Hezbollah, the majority of suicide attackers have not been religious at all, and that some of the religious ones have been Christian rather than Islamist. And we learn that suicide attackers are of both sexes and of various ages, incomes, and education levels.Ian Shapiro is Sterling Professor of Political Science at Yale University and Henry R.
