Both the public and the academic response to terrorism has been ahistorical, exaggerated, and closely associated with congenial political postures; moreover, the academic perspective is conditioned by the nature of individual philosophy.

Since there are no agreed definitions, no accepted limits to the subject, and no very effective academic approach, the situation seems unlikely to improve dramatically in the near future.
