You cannot punish the dead, but you can drive the living insane with fear
I might as well put this here.
Suicide the terrorism presents a unique challenge to conventional strategies of deterrence because not punishment can be inflicted upon the perpetrator once his act is complete. What remains, then, is deterrence. Yet, what does the suicide terrorist fear? Certainly, he fears getting caught prematurely, but most criminals do not count on getting caught before they can commit their crimes, for they would not be criminals if they did. Effective deterrence is still available, luckily. It merely requires that one embrace evil.
The solution is to attack the perpetrator's family. "Ok", it must be said to him, "like as not, we cannot catch you and if you die, we cannot punish you. But rest assured that, if you engage in terrorism, we will visit your family". Devout Muslims incessantly assert that they love Muhammed a hundred times more than they love their own mothers. This is a lie. They are human. Their professed superhuman love is nothing but grand-standing and a sham. They have the same attachments other people have and their psyches can be injured in the same ways. The would-be suicide terrorist must be subjected to a state of constant anguish, even if the authorities don't know of his intentions or who he is. The promise that must be made to all terrorists is simple:
The more savage the promised fate of the perpetrator's loved ones, the more effective the deterrent. Of course, one ought not to go overboard: only the immediate family members of the perpetrator should be targeted. The aim is twofold: the achievement of maximum psychological trauma and the avoidance of drawing the ire of distant relatives. In any case, the annihilation of the immediate family will be enough in most cases. The prospect of such a fate befalling his parents, siblings, and children is a horror few can withstand.
Such tactics are not new. They are time-tested and proven to be effective: the Russian (i.e. Jewish) mafia uses them and very few dare cross them. The Mexican Cartels use them too, and only those who believe that their identities are strictly secret and their families thereby protected from rival Cartels dare work for them. The human being is naturally attached to his kin. It is through his kin he finds meaning and support, and it is for his kin that he fights. Take this away from him, or just threaten to take this away from him, and he collapses, along with all of this fragile religious convictions.
I understand that one might balk at such tactics, but one cannot fight the uncivilized with the tools of civilization. To fight the savage, one must embrace the tools of savagery, of terror. We must become evil. We must become barbaric. There is no sin in that if we do it for the greater good.
All the terrorists in recent memories had mothers, had they not? If these mothers were to be gruesomely murdered, would that not deter future terrorists?
