Doubtful the cowardly murderers want to find out just what Israel will do if attacked.
A guy hanging in or around some god-forsaken village/cave out of the way (and not in or around an obvious target) would be practically unvulnerable. Look at the current AQ big sh*ts for an illustration, and I'm talking here about a village preacher and a guy who contributes to his collection plate. And carpet-nuking the areas of AQ support [to prevent its regeneration] would take thousands of warheads, more than a couple hundred Israel is believed to have.
