WASHINGTON (AP) -- Top administration defense advisers say the going is getting tougher in Afghanistan.
Admiral Mike Mullen, chairman of the Joint Chiefs of Staff, says he's not convinced the U.S. is winning in Afghanistan. But he told the House Armed Services Committee that he's "convinced we can."
He says better Afghan governance is needed along with more foreign investment and greater cooperation with Pakistan.
Defense Secretary Robert Gates told the panel that the insurgency in Afghanistan has gained "greater ambition, sophistication and coordination" since 2006.
He says that until the insurgency is deprived of safe havens, "insecurity and violence will persist."
