If the problem is Islam itself and to quote 'they just need to die' does that mean the answer is the mass slaughter of muslims? If not why not?
My second question is why do ISIS kill muslims? Given that their reason to fight is listed rather simplistically as because they want everyone to be muslim and that they kill more muslims than anyone else it would seem to me that they are sending very mixed messages.
The other problem is that of course not everyone fights for the same reason or with the same level of understanding of the conflict. A western convert is not going to have the same view as an unemployed local from Afghanistan or someone in a leadership position within ISIS.
Whilst I have always accepted that ISIS hate western liberal societies I can also accept that western involvement in the middle east is a contributing factor as is the fact that huge disparities in wealth in the middle east help ISIS recruit. As ever life and politics are not black and white.
The answer to this issue is not going to be won by just more bombs and guns, but that statement doesn't mean that more bombs and gun aren't needed at all. You can attack a problem from more than one direction.
