Afghanistan did not attack the United States on 9/11, and Saudi Arabia which was allegedly involved in the attacks has never been sanctioned for this and remains a close US ally, according to an American academic and commentator. 

American families of the victims of the September 11, 2001 terrorist attacks hope for answers about Saudi involvement in the incidents.

Where is Afghanistan's economy after trillions of US dollars spent and two decades of corruption and ineptitude, where is it headed to next, or what's left of it, under the Taliban?
