Usama bin Laden was interviewed by PBS
Frontline's John Miller in Afghanistan in 1998.
During that interview bin Laden bitterly complained about the presence of a U.S. airbase in Mecca that was placed there to facilitate Operation Desert Storm and should have been removed but wasn't. He also complained about Israeli settlements expanding more deeply into Gaza. He told Miller that if the airbase was not removed, and if the Jewish settlements in Gaza were not withdrawn, the U.S. would have cause to regret it.
Early in the Bush presidency a series of reports of extremely suspicious activity, namely a group of Muslims enrolled in flight training who wished only to learn how to fly a passenger airline but not take off or land, reached his desk but were ignored.
* A Presidential Daily Briefing in late 2000 warned that Usama bin Laden was planning an attack on the U.S. homeland. That warning was also ignored.
** Shortly after that warning the 9/11 attack on the World Trade Center took place.
But I've never heard any of this drum-pounding and blame-laying after that very clear example of gross and possibly criminal malfeasance on the part of the Bush Administration. And while it's possible the Obama Administration dropped the ball on the Benghazi assault (yet to be positively determined) the event comes nowhere near the level of negligence clearly demonstrated in the 9/11 example, nor do its consequences in any way compare in terms of magnitude.
