Leaving the Green Zone - by Sam Brannen, SWJ Blog

In the middle of Baghdad sits one of the United States’ greatest strategic liabilities in the Iraq war: a four square-mile swath of territory called the Green Zone (the “International Zone” when in polite company). Still crowded with the gaudy war memorials and palaces of Saddam’s regime that are too big to tear down, it is for many Iraqis the icon of U.S. occupation and a telling window into a post-surge security environment that looks more likely to loop back than move forward. The onetime seat of Paul Bremer and the Coalition Provisional Authority, the Green Zone is now shared by the sprawling Embassy Baghdad, the core of Iraq’s central government, and thousands of international contractors, including the infamous Blackwater security details. Green Zone denizens live in trailers, sometimes stacked one on top of the other, accustomed to the blare of the incoming round siren and ducking for cover in evenly spaced cement bunkers that are a bizarre juxtaposition to swimming pools, palm trees, and marble buildings.

Outside the Green Zone, American troops are fighting pitched battles in the high-density urban slums of Sadr City. Their objective is to reduce the mortar and rocket fire that has lately rained down on the Green Zone. By installing a massive cement wall to cut Sadr City in half, U.S. forces are attempting to corral militiamen and mortar teams out of range. As soldiers build the Sadr City wall, they fight for every inch in a slow grind that recalls trench warfare, taking casualties and under constant fire.
