ISIS strategy (Feb, 2015) to provoke a harsh crackdown on Western Muslims so they join ISIS
The Muslims in the West will quickly find themselves between one of two choices, they either apostatize and adopt the kufrī religion propagated by Bush, Obama, Blair, Cameron, Sarkozy, and Hollande in the name of Islam so as to live amongst the kuffār without hardship, or they perform hijrah to the Islamic State and thereby escape persecution from the crusader governments and citizens.
