One interesting fact I had been unaware of is that the networks supporting Chechen wahabi slaughter in Russia overlapped with the network involved in the 9/11 atrocity.
It seems Zacarias Moussaoui, the so called 20th hijacker who was arrested weeks before 9/11 was a recruiter for Khattab, a main commander in the Chechen war. Khattab was known to be linked to Bin Laden. However FBI commanders refused to do proper searches of Moussaoui's computer and home because at the time, Chechens were not considered "terrorists" by the Americans.
