Caveat: the book's conclusions do not hold for terrorism in general (8–9). Pape distinguishes among "demonstrative terrorism", which seeks publicity, "destructive terrorism", which seeks to exert coercion through the threat of injury and death as well as to mobilize support, and "suicide terrorism", which involves an attacker's actually killing himself or herself along with others, generally as part of a campaign (9–11). Three historical episodes are introduced for purposes of comparison: the ancient Jewish Zealots (11–12; see also 33–34), the 11th-12th-century Ismaili Assassins (12–13; see also 34–35), and the Japanese kamikazes (13; see also 35–37).
