Pentagon rethinking U.S. exit from Iraq: "Eight months shy of its deadline for pulling the last American soldier from Iraq and closing the door on an eight-year war, the Pentagon is having second thoughts.
Reluctant to say it publicly, officials fear a final pullout in December could create a security vacuum, offering an opportunity for power grabs by antagonists in an unresolved and simmering Arab-Kurd dispute, a weakened but still active al-Qaida or even an adventurous neighbor such as Iran.
The U.S. wants to keep perhaps several thousand troops in Iraq, not to engage in combat but to guard against an unraveling of a still-fragile peace. This was made clear during Defense Secretary Robert Gates' visit Thursday and Friday in which he and the top U.S. commander in Iraq talked up the prospect of an extended U.S. stay."
