The tactical level is worrisome, but it is not the priority of terrorism. The real success is at operational level: it is the “functional blockade”
Even when it fails, terrorism gains, in terms of the costs inflicted upon its target: it is successful as it can still impose economic and social costs on the community and influence the latter’s behaviour over time as a consequence of new security measures aimed at safeguarding the community: this effect is what we call the “functional blockade”, able to reach the average of 82% of the cases. The cost-benefit ratio is, no doubt, in favour of terrorism.
