Iraq strategy geared to U.S. pullout

BAGHDAD — U.S. commanders plan a summer of stepped-up offensives against Al Qaeda in Iraq as they tailor strategy to their expectation that Congress soon will impose a timeline for drawing down U.S. forces here.

The emphasis on Al Qaeda, described by commanders in interviews here this week, marks a shift in focus from Shiite Muslim militias and death squads in Baghdad. It reflects the belief of some senior officers in Iraq that the militias probably will reduce attacks once it becomes clear that a U.S. pullout is on the horizon. By contrast, they believe Al Qaeda in Iraq could be emboldened by a withdrawal plan and must be confronted before one is in place.
