This is an excerpt from journalist Robert Fisk's book "The Great War For Civilasation," a well-researched, graphically-described history of the Middle East from WWI to the mid-2000s:
I remember an American search operation in Baghdad just after Saddam's capture [13 Dec., 2003], all door-kicking and screaming and fuck-this and fuck-that and, just a few metres away, finding a message newly spray-painted on a wall. Not by hand but with a stencil, in poor English perhaps, but there were dozens of identical messages stencilled onto the walls for the occupiers. "American Soldiers," it said. "Run away to you home before you will be a body in [a] black bag, then be dropped in a river or valley." - p. 1006
