Robert Pape examines other campaigns to see if the "dynamics that make religious difference important" are present in other terrorist campaigns, acknowledging the difficulty of the inquiry (126–29). He offers detailed analyses of Lebanon (129–39), Sri Lanka (139–54), the Sikhs in Punjab (154–62), and the Kurdish PKK in Turkey (162–66). His conclusion: "Religion plays a role in suicide terrorism, but mainly in the context of national resistance" and not Islam "per se" but "the dynamics of religious difference" are what matter (166–67).
