If Panetta imagines the Pak Army will b a pushover like Iraqis, he should think again. If USforces attempt an invasion of North Wazirstan they will meet reaction not only from militants but from an army which will not accept flagrant violationof national sovereignty. I know pak army, and I state flatly that man-for-man it will hammer any opponent , no matter if the skies are horizon filled with US bombers. Does US think this is a price worth paying??
