Listen to what the soldiers have to say.
A few nights ago, for example, we witnessed the death of one American soldier and the critical wounding of two others when a lethal armor-piercing explosive was detonated between an Iraqi Army checkpoint and a police one. Local Iraqis readily testified to American investigators that Iraqi police and Army officers escorted the triggermen and helped plant the bomb. These civilians highlighted their own predicament: had they informed the Americans of the bomb before the incident, the Iraqi Army, the police or the local Shiite militia would have killed their families.
As many grunts will tell you, this is a near-routine event. Reports that a majority of Iraqi Army commanders are now reliable partners can be considered only misleading rhetoric. The truth is that battalion commanders, even if well meaning, have little to no influence over the thousands of obstinate men under them, in an incoherent chain of command, who are really loyal only to their militias.
Similarly, Sunnis, who have been underrepresented in the new Iraqi armed forces, now find themselves forming militias, sometimes with our tacit support. Sunnis recognize that the best guarantee they may have against Shiite militias and the Shiite-dominated government is to form their own armed bands. We arm them to aid in our fight against Al Qaeda.
However, while creating proxies is essential in winning a counterinsurgency, it requires that the proxies are loyal to the center that we claim to support. Armed Sunni tribes have indeed become effective surrogates, but the enduring question is where their loyalties would lie in our absence. The Iraqi government finds itself working at cross purposes with us on this issue because it is justifiably fearful that Sunni militias will turn on it should the Americans leave.
In short, we operate in a bewildering context of determined enemies and questionable allies, one where the balance of forces on the ground remains entirely unclear. (In the course of writing this article, this fact became all too clear: one of us, Staff Sergeant Murphy, an Army Ranger and reconnaissance team leader, was shot in the head during a “time-sensitive target acquisition mission” on Aug. 12; he is expected to survive and is being flown to a military hospital in the United States.) ...
