Establishing de-radicalization centers to fight the jihadist plague, either in Muslim countries or in the West is a futile endeavor. They cannot erase centuries of indoctrination by religious authorities in Arab and Muslim countries.
The preaching of hatred of all others (Kuffār), for not following in the footsteps of the Prophet Muhammad, include instructions to dehumanize and subjugate those who cave-in and preferred methods to kill the rest, especially the Jews.
This has been re-enforced by local mosques and madrassas in Muslim dominated territories over centuries, and more recently in non-Muslim countries. Since the mid 1960s the Saudi royal family and the Saudi Kingdom have funded Islamic radicalization.
