I think we have reasons to be afraid. Not of the Islamists but of the general pattern. If we follow the idea that what you see in the Arab Spring is akin to the revolutions of 1848 then what follows next is a period of instability ultimately culminating in a period of fierce nationalism. At the risk of sounding crazy I am going to advise you to watch for a wave of abstract or impressionist art sweeping across the Arab world. Allong with those radical shifts in the art world will come changes in the political philosophy's. The ethnic/tribal bonds will lose grip replaced by nationalism. Then expext old rivalries to be revived.
