Jihadist weaponry

The image of Hayat Boumeddiene, alleged accomplice of the terrorists responsible for the Charlie Hebdo slaughter, shows her using a crossbow, a weapon of choice for many Arabs until recent times. It had to be because innovation of arms, as with other technologies, lagged behind the West as many Middle Eastern Countries lived a third world existence still seen in Yemen and Somalia today. Much as they despise the West it is interesting that today the typical Arab Jihadist wouldn't be without its 'satan' technology; the Kalashnikovs, the rocket launchers, grenades, the kevlar based body armour, the mobile phones, the computers and the world-wide web. All available from the decadent West because since the days of the Prophet their capacity for innovation has been stifled. Where are the Arab machine guns, the Arab tanks, Arab fighter jets etc? Indeed it could be argued that if it hadn't been for oil, most of the Arab countries would still be third world incapable of financing global terrorism.
Is it not the case that although they claim to hate the West and its values in reality they know that they are jealous of the advanced way of life to be found, for instance, in Europe and America and like spoilt children would prefer to see this destroyed rather than live perpetually in the shadow. The leaders of the more enlightened Muslim States are already taking steps to ensure their survival post oil. They are buying as much prime land in Europe and America as they can and I wonder what the leadership of Al Qu'eda think about that!
