From Curzon to Bush -- all have said catagorically that they will NEVER allow Political Islam  to be re-created. So, why are they fully supporting a gang of Khawarij, which is declaring Khilafat, moving freely across deserts of iraq and Syria and NO US/NATO/Israeli plane bombing them????Because Khilafat is the political Islam whose final destination will be the Arrival of Imam Mehdi(as). ISIS is Khawarij plus Israeli army !! That is their reality..
