Thread undrift.

From this report in the International Herald Tribune dated April 6th:

Col. W. Blake Crowe, the senior Marine commander for the region, said...insurgents had shifted their operations to towns along the Euphrates River closer to Baghdad, including Haditha... "Haditha's really the hub" of insurgent activity in western al Anbar now, he said.

It seems reasonable to speculate that actions such as the massacre in the town last November in which Iman's family were killed can't exactly have hurt recruiting for the insurgents.
