they didn't get the leaders who are palnning the attacks. Like arresting the drug users and letting the dealers and suppliers and smugglers go free. When will we learn?

When kids (okay, I grant you that many of the teenagers involved are only borderline kids, but there *are* kids doing it, too) blow themselves up in buses, killing a dozen people, I doubt very much wholesale slaughter of the so-called leadership would work. These things are happening far too much in a "take your own initiative" way.

Yeah, someone is supplying the bombs and bomb materials. But they're probably being supplied by lower-level flunkies rather than the "leadership", and in any case by this point I'd bet there are sizable caches of bomb materials and kids who know how to use them anyway.
