The reasons are: 1) Even from the ranks of non-rich Muslims, financial and other forms of support for terrorists can bubble up. One thing that has made it hard to figure out where Osama Bin Laden is hiding (assuming he's not dead) is the large number of households in which he'd be a welcome guest. 2) Pro-terrorist sympathies make it politically hard for governments of some Islamic states to fully join the war on terrorism. And new information technologies that defy centralized control mean that authoritarian governments can less and less control the opinions of their people and less and less afford to ignore them. 3) Indeed, such is the pluralizing power of this technology that, as we'll see in a future installment of this series, there is reason to believe that authoritarian regimes in Islamic states are doomed, so that sooner or later governments in the Islamic world will be more direct expressions of popular sentiment. In moderating today's popular sentiment in the Islamic world, we may be moderating the policies of tomorrow's governments in the Islamic world.
