Extremist ideology and the associated mass-casualty acts of both domestic and foreign terrorism remain a threat to the global community. Ideology is the manifestation of deeper beliefs based upon intensely held but rarely understood underlying assumptions. A bullet may kill an extremist but it will not kill extreme ideology; that is, “Bullets do not kill ideas. . . . A ‘hot’ war against an idea is destined to be a losing prospect.” Arguably, 9/11-like events in the form of large suicide bombs will be replaced by mass media exploitation, political chess, electoral manipulation, and cyber intrusion via social influence mediums. These events will likely occur just beneath the surface, more improvised explosive device (IED) than weapon of mass destruction (WMD).
