"We've moved beyond the message stage here. I think the US has had it with messages that don't get any action, and that is why the president authorized this," says Kamran Bokhari, director of Middle East analysis for Stratfor, an intelligence consulting firm in Washington. "This says loud and clear, 'We're fed up.' "
Even before the July order, the US had undertaken covert operations in Pakistan's tribal areas. Moreover, the CIA over the past year has stepped up missile attacks by the unmanned Predator drones it operates to hit targets in the region. That increase has coincided with a deterioration of the war in Afghanistan, where the Afghan Army and NATO forces have come under increasing attack from militants crossing over the rugged and lawless border from Pakistan.
But Bush's orders, first reported in The New York Times Thursday, mean that operations against insurgent sanctuaries will become overt and probably more frequent. A Sept. 3 ground assault involving US commandos dropped from helicopters targeted a suspected terrorist compound. Missile attacks by the CIA's unmanned drones, including one Friday reported by Pakistani officials to have killed at last 12 people, are also on the rise.
