Just as interesting as Mossad is the team in Norway who watch jihadists, so Thomas Hegghammer's article evaluating ISIS is a good read:http://www.lawfareblog.com/2014/07/t...ted-caliphate/

It ends with:
The bottom line is that business in the jihadi world will largely continue as usual after the declaration. Over time, the new caliphate will come to be seen as just another militant group, albeit a very presumptuous one. In the meantime, it is probably wise for Western governments to let the internal jihadi debate run its course. Premature military intervention will give the caliphate a jump start it does not deserve.
