Not a Deterrent

Jihad attackers who want martyrdom are not deterred by the prospect of the death penalty. To these terrorists, dying in the cause of advancing their beliefs is the highest reward. What the Russians reputedly did in Lebanon after a couple of their people were abducted decades ago is a real deterrent, as the Russians were said to have wiped the family and tribe members of the kidnappers from the face of the earth. After that, no one bothered the Russians again in Lebanon.
