The greatest terrorist recruiting tool is the Israeli bulldozers taking out palestinian homes in the middle of the night.
You just created homeless people with nothing to lose, and where their home used to be, they see a new foreign settlement or road where their home was -- well what is more dangerous than justifiably enraged people with nothing to lose? There is a reason these people have been radicalized, a good part of it is a sense extreme injustice, helplessness and desperation. Of course some of these poor people just become pawns for rich people with grand evil schemes, but they wouldn't be pawns if their lives weren't already a living hell. It may be convenient and expedient to dehumanize and demonize palestinians, but there is a reason they have been radicalized in recent years. None of this implies I agree with what the extremists do, but knowing the reasons may help to prevent it in future...

I think we should retaliate fiercely again bin laden and his cronies wherever they are (afghanistan, Chechnya, pakistan, etc..), but lets be honest about the causes of hatred. It didn't come from nowhere...
