i was there in 2007 through '09. what's interesting is they now have the support of the central government. they have trust and faith in their leaders in baghdad. that is critically important. because they are rebuilding this army from a nationalistic perspective and guarding all of iraq, not just baghdad. so what is happening now, you're not only seeing the iraqi security forces, the iraqi army going to mosul, you're also seeing kurdish forces attacking from the east. you're seeing the iraqi police forces being reinforcing within mosul. you're even seeing tribal leaders in the province. yesterday, tribal leaders attacked an isis convoy heading from mosul to raqqah. they killed 12 fighters from a tribal force perspective. you also have the military units that are reinforcing the fight. probably will not go into mosul, but they are there. so you're seeing a pan iraqi force conducting this operation.
