Terrorism will continue to appeal to its perpetrators for mainly three age-old reasons. First, terrorism is a weapon of the weak; it appeals to racist militias, religious fundamentalists, ethnonationalists, and other minorities who cannot match the military might of their "oppressors." Second, terrorism is a way to assert identity and command attention; as such, it is an end in itself. Third, terrorism is appealing, especially to those with a religious fervor, as an expedient way to achieve a new future order if only by wrecking the present.
Political terrorism is an idiom of despair, the last resort of those with nothing to lose, those who feel they have been deprived of their humanity, of people who are convinced that, no matter what they do, they are in a losing race with death, be it from hunger, thirst, pollution, incurable diseases like AIDS, now even from genetically enhanced food. At the same time, they see new vistas for ever more prosperous and meaningful lives opening up before others. So wide is the chasm between the haves and have-nots in the world of today that the latter feel they have nothing in common with the former, not even a shared humanity. Once this sense of alienation takes hold, the indiscriminate killing of the Other can appear as a way of evening the score.
