"The presence of foreign troops is an understandably combustible issue for Iraq; the scars of past battles are, for many Iraqis, equal to current battles against the Islamic State," the report stated.
There is a sizable percentage of Iraqis, the report noted, who believe "the US and other foreign powers are in some way supporting the Islamic State as a disruptive wedge against a stable Iraq."
Most foreign troops, specifically US forces, will be stationed at remote bases and "largely kept out of public sight and mind."
Washington’s strategy is to use small and incremental deployments of US troops, leaving most ground combat operations to local forces such as Kurdish troops approaching Mosul from the north and Iraqi Security Forces from the south.
The Islamic State, also known as Daesh in Arabic, has controlled Iraq’s second largest city of Mosul for the past two years.
