U.S. officials believe elements of Pakistan’s intelligence agency, Inter-Services Intelligence, are continuing to protect the Haqqani network to help it retain influence in Afghanistan once the U.S. military eventually leaves the country. U.S. officials say the support includes housing, intelligence and even strategic planning,

During a trip to Pakistan last month, Adm. Michael Mullen, chairman of the Joint Chiefs of Staff, chose not to raise the issue of an offensive against the Haqqani network—a departure from the message U.S. defense officials delivered earlier this year…

Pakistan has failed to act on detailed intelligence about the Haqqanis provided in recent months, said a senior military official. “Our forces have put a significant dent in the Haqqani network,” said the official. “It would be good if the [Pakistanis] would do the same on their side.”
