Fox News Sunday host Wallace and Associated Press reporter Weiss follow Countdown 1945 with an engrossing if familiar account of the killing of al-Qaeda leader Osama bin Laden in May 2011. Toggling between key players including CIA director Leon Panetta; Adm. William McRaven, who planned the mission; and Navy SEAL Robert O’Neill, who fired the shots that killed bin Laden, the authors start in August 2010, when Panetta first learned that CIA agents had tracked a suspected al-Qaeda courier to a heavily fortified compound on a dead-end street in Abbottabad, Pakistan. Aerial surveillance led operatives to believe that a compound resident they nicknamed “the Pacer” might be bin Laden, though an attempt to collect DNA evidence confirming his identity through a CIA-funded vaccination program proved fruitless.
