Question: (CNN) -- What role did Pakistan play in the operation against Osama bin Laden? I would be surprised if Pakistan played a significant role in the operation to apprehend and kill Osama bin Laden, based on the fact that the drone strikes that the U.S. conduct in the tribal areas are done covertly, the authorities in Pakistan are not informed until the very last minute, because of the fear of information leaks. An operation of this scale in the central urban heartland of Pakistan would mean that information would be kept on a need-to-know basis. Only a few people within the CIA would have known about this operation, it would definitely not have gone out to another country's intelligence agency, especially when there's so little trust with the ISI [Inter-Services Intelligence, the Pakistani intelligence service].Gohel: Pakistani authorities will have been kept in the dark because of a lack of trustProtests and propaganda set to follow the death of Osama bin Laden, he saysGohel: Retaliation attacks are likely, but may not happen immediately. 
 Question:U.S. interests, U.S. personnel, _ embassies and consulates will have to take extra precautions.
