Unless I misinterpret, this modern islamofascism had its' roots in the Muslim Brotherhood , then the affinity the Muslim leadership had for the Nazi's, as the grand mufti did, courted Hitler, began an SS unit of Muslims. Post war, with the establishment of Israel (something that had been planned since the late 19th Century) brought it all together.
The 60's and 70's saw us distracted and there was no one to slap these terrorists down except Israel, and that was simply not enough.
