[Journalist and author Jere] Van Dyk says that if it could ever be proven that the papers date back to before the founding of the Muslim religion, or if it became evident that there was a Jewish community there at that time, then it could change the region.I just don't see this happening; I can't see the Taliban taking that much interest in what secular historians are saying. But I'll be very happy if I'm wrong.
“The Taliban, who are deracinated – cut off from their culture – are deeply politicized and have been for decades by Pakistan, which has its own agenda in Afghanistan. They are deeply religious – ‘We are Muslim; We want to rid our land of the infidels; We want a pure Islamic government,’ not unlike the one Mohamed is said to have created in Medina – now if it becomes clear, if there’s an increasing amount of information, and the Taliban begin to hear that, wait a minute, ‘We are descended from those who are at war with the Arabs, and our allies here Al-Qaeda’ – then it could possibly change how they look at everything.”
