Naw. They were made up of disgruntled teenagers and young adults, pissed off at the West for leaving them in a vacuum, replacing their shitty leader with nobody along with an infrastructure wrecked.
They got reason to be pissed. They doing it right? No. They’re assholes. But unlike Al-Quada, which did have a religious component to it, ISIS is just angry ppl getting a thrill of a little sense of power and media exploitation. Young people know how to work the system while old generals lap it all up.
