That's what this Marine major says, though more politely than my post title does:

Most of the violent news is true; the death and destruction are very real. But experienced military officers know that the horror stories, however dramatic, do not represent the broader conditions there or the chances for future success. For every vividly portrayed suicide bombing, there are hundreds of thousands of people living quiet, if often uncertain, lives. For every depressing story of unrest and instability there is an untold story of potential and hope. The impression of Iraq as an unfathomable quagmire is false and dangerously misleading.

It is this false impression that has led us to a moment of national truth. The proponents of the quagmire vision argue that the very presence of U.S. troops in Iraq is the cause of the insurgency and that our withdrawal would give the Iraqis their only true chance for stability. Most military officers and NCOs with ground experience in Iraq know that this vision is patently false. Although the presence of U.S. forces certainly inflames sentiment and provides the insurgents with targets, the anti-coalition insurgency is mostly a symptom of the underlying conditions in Iraq. It may seem paradoxical, but only our presence can buffer the violence enough to allow for eventual stability.
