The push to reclaim Mosul and Raqqa is just like a successful radiation treatment, it is shrinking the Islamic State’s caliphate that was once advancing unabated across Iraq and Syria. Even though their land mass and fighters are dwindling, their sympathizers and their fundamentalist ideology has spread across the world like a cancer.
Islamic extremists in Europe, for instance, have plans to conquer the continent with fundamental Islam to join a future caliphate. They will not, however, wield the sword; pillaging, raping and killing infidels everywhere they go, planting their black flags on every hilltop. Mind you, this is the militant fantasy of many fledgling Islamic would-be warriors, but the truth is that blood is not for everyone. The future jihadist will conquer Europe through the more civilized method of population replacement.
