U.S.: 'Lack of Trust' in Pakistanis Fueled Helo Disaster

U.S.: 'Lack of Trust' in Pakistanis Fueled Helo Disaster: On the surface, the cause of the disastrous November U.S. helicopter mission that left 24 Pakistani soldiers dead was faulty maps and miscommunication. But the official U.S. investigation into the disaster points to deeper causes: the U.S. doesn't think it can trust its Pakistani counterparts with intel on its missions; and the Pakistanis stonewall the U.S. about their own operations.
