THE CIA''S AFGHAN ARABS

During the Cold War the CIA trained Saudis to fight as proxies against the Russians in Afghanistan. After the Cold War these same Arabs were funnelled into Chechnya to fight the Russians within their own borders. Bin Laden was part of the arab cadre trained by the CIA. In the 1990's  Bin Laden used a trackable and tappable satellite phone. The NSA knew his whereabouts and could eavesdrop on his conversations with the phone. So, American intelligence knew his intentions and they know he was not responsible for 911.
