ISIS has lost a lot of territory but that hasn’t translated into a loss of supporters. For classes in psychology, political science, marketing, history, and sociology: ISIS has become some sort of religious obligation. ISIS aims to be at the forefront of an end-of-days battle. It’s pitting its fighters against the West to establish a Muslim homeland. And that’s the second reason the group has had such staying power. It hasn’t asked its followers to wait to make history. The ISIS guys argue that the time for the return of the empire has come now. And they have been good at promoting their symbols, promoting their brand and selling young men and women on the idea that God’s kingdom on earth has returned.
