It is working well, I think. I believe there would have been many more suicide bombings if not for that.
You see, the families of suicide bombers receive large amounts of money as a reward (though a lot less money than they used to get, now that Saddam Hussein is no longer in charge). The Israelis have to make sure that the bounty-money is made worthless, so that fewer Palestinian teenaged barbarians decide to kill themselves to benefit their families.
Now they're reduced to recruiting young children and pregnant unmarried women. One group is easy to fool, and the other has nothing to lose since her family will kill her themselves before her pregnancy starts to show.
So I'd say it's been effective.
There was an article posted here yesterday about 2 pali suicide bombers turning themselves in for FEAR OF THEIR FAMILIES HOUSE DEMOLISHED.
