Osama bin Laden still hoped to pull off one big attack, according to newly revealed documents seized during the raid that killed the al Qaeda leader. The documents were posted online by the Combating Terrorism Center at West Point on Thursday. The report, titled Letters From Abbottabad: Bin Laden Sidelined, consists of letters totaling 175 pages in their original Arabic and 197 pages in English and ranging in date from September 2006 until April 2011. While later letters detail bin Laden's disappointment in al Qaeda’s waning influence, he does take some jabs at U.S. Vice President Joe Biden, detailing a plan to assassinate President Obama that would leave the “unprepared” Biden in charge and thus put the nation in crisis.
