Abstract
Understanding what causes terrorists to conduct mass-casualty attacks is essential. In this essay, we argue that religious terrorist groups and terrorist groups embracing an ideological/mythic pattern similar to religion that conduct such attacks are motivated by what we label the symbolic DNA of terrorism. Terrorist groups such as al Qaeda perceive that their identity is threatened, and believe that the only way to remove that threat is by reconnecting with their heroic past. The myth provides a narrative that encourages group members to engage in “God's work” against the oppressor in order to destroy the threat and regain past heroism to achieve a glorious future. In this essay, the symbolic DNA of terrorism is described in detail, with a focus on al Qaeda. We conclude by drawing implications for the Global War on Terror.
