ms. gambir, how can you describe i.s.i.s. for us?it seems there's a coalition of arab states that are against them in the region, yet we are talking about them a year after the caliphate and we're talking about the counteroffensive, we have seen the beheadings and the people set afire. how is it that they continue to grow when they are doing so much countercounter to so many forces? >> that's ogreat question, the sanctuary that it has in both syria and iraq, the cities it holds are the key claim to legitimacy. the caliphate and the leader of all muslims that has proven to be a huge message not only in the middle east but all over the world. we're seeing individuals in the west including the u.s. try to launch attacks in i.s.i.s.'s name and the longer it's able to stay within iraq and syria and restain that sanctuary the more it is able to claim that it is resilient and that it will remain. and now we're coming upon a year of its existence and as a caliphate within iraq, and it's able to claim that it has remained. >> and mr. korb thi
