So basically there has always been an aspect of Islam that harked back to the glories of jihad and so on. Wahabism took its cue from Ibn Thamiyya, but it was Saudi Arabia funding Wahabism internationally in the latter half of the 20th Century onwards and various other geo-political / ideological factors (including Maududi in Pakistan and Qutb in middle-east and also after 1979 to counter the Shia ascendancy post revolution Iran) that planted these seeds that are now blooming.
Saudi Arabia has its ideological fingerprints on this.
Is this a reasonable joining of the dots, or at least a start?
I would say so. Then also, as you mentioned previously, that there is a greater awareness now of the life of the Prophet and the actual words of Quran. Due to education, due to the push to learn Arabic, due to.. everything. With a steady pressure from Saudi Arabia to further this. But I like to blame it all on the Saudi government. It's a convenient scapegoat, a common one.
It is just so nightmarish now, with terror, that it makes the days of the village headman/Imam sounding out the Quran and giving his own peaceful interpretation of it (of course you want your villagers to be peaceful) look rosy. But then I remember that Partition happened without much influence from Saudi Arabia (I assume) and I despair.
