kenneth pollack is a senior fellow at the brookings institution. let me begin with this question. name almost any outrage in the middle east. iraq's invasion of kuwait. the gassing of kurds to read the bombing of the uss cole. -- the gassing of kurds. the bombing of the uss cole. the protagonists would find both apologists and detractors. but with one breathtakingly vicious murder, the islamic state change that dynamic. i want you to give me a sense of that dynamic. ken? >> the arab world especially the sunni arab world, has been ambivalent about the fight against isis. they don't like isis and see it as a threat. they see another threat, in many ways a bigger threat. the shia forces led by iran. the american-led effort against isis has suffered because sunni states are not willing to participate as much of the u.s. would like. what may have happened as a result of the killing of this pilot is we may now see the sunni states coming fully on board. saying, as much as we don't like the shia isis clearly has got to be dealt with. we will see more of throw did and enthusiastic support

. >>> let's bring in shane harris and from the brookings institution, kenneth pollack, a former persian gulf military analyst. ken, i'll start with you. you just came back from iraq and wrote a piece saying that isis is losing on the battlefield in iraq but where they have the most power is induceing fear and overreaction not on the battlefield but in videos and by killing our people. is this what is going on here? >> this is part of it. and we need to recognize while there is a military piece to this campaign the military campaign is more important. and this is what i talked about in my piece. look at the name. it uses terror for its purposes. it is trying to frighten other countries to deter them and it is trying to speak to the disenfranchised youth of the arab world, people angry and frustrated and looking to strike a blow against the powers that they think oppress them. for these people these actions by isis help in their recruiting. so they are trying to frighten up and reach out to people who they think will be receptive to their message. >> shane, we got confirmation with kayla
