I really don't see Bin Laden's death as a recruiting tool for AQ. Before Bin Laden's death, AQ wanted to kill you and your children because you were Infidels who did blah blah blah. After Bin Laden's death, AQ wants to kill you and your children because you are Infidels who did blah blah blah (and killed Bin Laden). It's not like AQ was a knitting circle before Bin Laden became chum, and now they're reluctantly sharpening their beheading knives and looking for defenseless captives to mutilate.
