The 9/11 attacks have already produced a substantial literature that seeks to explain the roots of Al Qaeda's strategy of targeting the United States. Explanations range from simplistic statements—“They hate us,” “They hate freedom”—to arguments about revenge or punishment for various American policy choices, to more complex arguments that Osama bin Laden and his associates sought to draw America into a trap of sorts. One problem, of course, is that no one really has much of an idea of precisely what led bin Ladin and his top associates to plot the 9/11 attacks. Scholars do not, quite frankly, have a lot to work with here.
