s arabia are not sort of following the u.s. strategic goal here? >> well, i think those two really do have to be on board or we have to be on board with them in terms of priorities, and i think we need to look at what they are trying to accomplish, what their goals are. as i said, most of these countries have another agenda. the saudis are worried about iran, the turks more about the kurds and so on. but they're both united in the fact that assad has to go before you can make any real progress against isis. i think we need to listen to them if we want them to be active and aggressive members of the coalition. but the reality is you hear people talk about sending combat formations from arab nations into iraq to fight isis. that's just not going to happen. first, they are not going to send their troops, not willing to send their troops, but, second, the iraqis probably wouldn't allow them to come anyway.
