The NY Times reports from Mosul that
Given the weak performance of Iraqi forces, any major withdrawal of American troops for at least a decade would invite chaos, a senior Interior Ministry official, whose name could not be used, said in an interview last week….
Infiltration remains a problem. After the uprising, the Mosul police chief was quickly dismissed and was later arrested on suspicion of complicity with the insurgents.
When a captain in the Mosul police force, Abu Muhammad, was asked if the police had been penetrated by the mujahedeen, he took a long, deep breath.
"Yes, and this is the problem, and I do believe that they have contacts with senior policemen in Mosul," he said. "There is kind of cooperation between the two parties."
On the flip side, there's this:
There are some bright spots among individual battalions of the Iraqi National Guard troops and Iraqi commandos. When operating under the direct control and oversight of American forces, some have helped in raids and other missions and continue to be used when American commanders want to enter mosques and other culturally sensitive targets, as happened in Falluja.
Whole thing here.
