GIs May Be in Iraq for a Decade: General

US forces could be needed in Iraq for a decade to battle insurgents, the top coalition commander said Sunday while vowing a "forthright" review in September on whether a troop surge is working.

Speaking on Fox News, General David Petraeus said there was broad recognition in Washington that Iraq's daunting challenges would not be resolved "in a year or even two years."

"In fact, typically, I think historically, counter-insurgency operations have gone at least nine or 10 years," he said.
