The suicide bomber is the new and most dangerous weapon of the twenty-first century. Not that it's entirely new or hasn't been used to great effect before, but now it has grown so pervasive that it has made scattered bands of warriors improbably powerful. Asymmetrical warfare is the order of the day. Good defenses are rare.
We've seen these human missiles spread from Palestine to the Middle East generally into America and Europe. Where will they turn up next?
Security measures are bound to remain inefficient. The worst security measure is certainly the one we've taken. Adding layers of bureaucracy to existing spy agencies will make us -- and has probably made us -- less safe. The more organizations are involved, the less likely they are to "connect the dots."
I wrote as much four years ago when I warned that structural solutions, tinkering with organizational systems, never work. Unfortunately that is the solution to which America always gravitates.
