Because it requires thinking.  UBL was a CIA/DS creation as was AQAP and related entities.  AQAP has been largely snuffed, with ISIS' rising as AQAP2.0.  THe Shia/Sunni lines are indifferent.  The wars are all about tribalism, $$$, children, and drugs.  Same shit has been going on for 2000 years.  DS just leveraged it to milk the resources. It was educational material for UBL just like the Map is for us.
