As reported by Raymond Ibrahim, calls have already begun amongst Muslim clerics for the destruction of Egyptian antiquities, now that Islamists appear possibly on the cusp of grabbing control from the military in that country. That includes real calls for the destruction of the great pyramids.
Of-course, it’s not going to happen overnight. Egypt has long depended on income from tourists, and such acts of brazen national self-destruction will not occur soon nor without serious opposition. Nevertheless, there is an inescapable logic at work. Symbols of paganism—and indeed of any other religion—do not enjoy tolerance by genuine Islamic regimes. History and a quick look around the world can assure you of that much.
The Arab Spring keeps ticking along.
