David Warren has a fascinating theory about what is really wrong with the Islamic world:

For in the face of almost all the appearances, I have come to at least the hunch that the Muslims today are in something like the fix of the Christians (and the Jews, for that matter). That while it is true there are cells of believers, for the most part faith has been lost. That religious observance continues outwardly as it did in, for instance, late Victorian England, but inwardly people no longer believe, have gone "beyond belief".
