The War as We Saw It - New York Times
The claim that we are increasingly in control of the battlefields in Iraq is an assessment arrived at through a flawed, American-centered framework. Yes, we are militarily superior, but our successes are offset by failures elsewhere. What soldiers call the "battle space" remains the same, with changes only at the margins. It is crowded with actors who do not fit neatly into boxes: Sunni extremists, Al Qaeda terrorists, Shiite militiamen, criminals and armed tribes. This situation is made more complex by the questionable loyalties and Janus-faced role of the Iraqi police and Iraqi Army, which have been trained and armed at United States taxpayers' expense.
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.
