Listening To The ”Emir”: The NSA & Osama Bin Laden

In this episode of The Darkened Hour, the intelligence services and their investigation into a young Saudi who was an integral part of the Soviet withdrawal of Afghanistan in 1979. As Bin Laden was expelled from his home country of Saudi Arabia, he and along with his Arab mujahid along with Egyptian members of the Islamic Jihad, relocated to Sudan. The NSA thru a separate investigation of a Hamas operative in New York City became aware of a satellite phone which was delivered to Khartoum. This phone was an unencrypted device which the FBI informed the NSA about. By 1993, the NSA had collected the data and recorded all the calls. One number in particular was raising the interests of the analysts at NSA. It was traced back to a house in the country of Yemen, where it's capitol, Sana'a was the location. It belonged to an associate of BIn Laden's from Afghanistan, Ahmed al-Hada.. This became the conduit for Bin Laden's Al Qaeda group which now relocated back to Afghanistan in 1996. The NSA shared with the CIA about the house in Yemen, where the agency started monitoring the movements of those coming and going from this house between 1996-2001. With the NSA listening to Bin Laden's satellite phones between, 1992-1998, and the phone in Yemen, and the CIA conducting human intelligence of the Yemen house, what exactly did the intelligence produce over the years? More importantly, what didn't they share?
