Graduating from college with a degree in Middle East studies, Rossmiller joined the Defense Department's Intelligence Agency in 2004 and soon volunteered to join a DIA unit in Iraq. He vividly recounts his six-month tour—the physical misery of the environment and the frustrations of feeling his work rarely made a difference. Good intelligence, he explains, begins with people on the spot (in this case usually Iraqis), who take risks but supply information that is often fragmented, out-of-date and even self-serving or false. Analysts, such as the author, tease out useful data and deliver it quickly to fighting men. Hobbled by clueless superiors and their turf wars, as well as ignorance of Iraqi culture, DIA units, including Rossmiller's, witnessed American forces repeatedly acting on poor or outdated intelligence. They killed and arrested plenty of genuine insurgents but also killed, arrested and infuriated many innocent Iraqis, which crippled their efforts. Back in Washington, Rossmiller discovered the agency under pressure to provide good news for the Bush administration. Superiors regularly rejected his analyses of Iraqi politics as "too pessimistic." If repeated rewrites lacked an upbeat conclusion, superiors inserted one. That his predictions turned out to be correct made no difference. This intense, partisan arm-twisting devastated morale, resulting in an exodus of agency experts, including the author. Rossmiller gives a lively insider's view of the petty and not-so-petty politics that affect the intelligence our leaders receive in their efforts to pacify Iraq; it is not a pretty picture. (Feb. 12)
