I am sure you know that I am not endorsing the murder of anybody. However, killing the bombers family would probably be a very effective deterrent to future bombers and it seems to fit neatly with the morality of the murders by the Pals. The fact is, Israel will not go there.
Blowing up the residence of the family and all their neighbors might have some similar effect but I doubt it. Amazingly, there are those that will say that blowing up buildings is no better than blowing up children.
