the key question is how do you find proxy forces to join the forces, the others fighting the kurd or others inside syria. it's a phenomenal mess. it's hard to see how any nato or western nation would want to insert troops into that. they would simply become a polarizing lightning rod, a, frankly, and you would have to ask, where would you insert them from? nato and turkey, they have their own agenda against the kurds and iraq has a militia doing much of the fighting. this is an impossible question to answer, kristian. >> nick paton walsh, stand by in erbil in iraq, give us a scope of this story right now. i want to bring in deb feyerick right now with some breaking news. we've been talking about a raid underway in belgium. a police raid underway in belgium, perhaps connected to the terror attacks here. deb joins us by phone right now. deborah feyerick on the phone.
