Story summary

Lawrence Wright's Pulitzer Prize-winning book "The Looming Tower" details the origins of Al-Qaeda and highlights significant bureaucratic failures in U.S. intelligence agencies before 9/11. According to the narrative, the CIA knew for over a year that two operatives linked to the terrorist group were inside the United States but only informed the FBI on September 12, 2001, the day after the attacks. The book focuses on four key figures: Osama bin Laden, his Egyptian deputy Ayman al-Zawahiri; former Saudi intelligence chief Prince Turki al-Faisal; and FBI agent John O’Neill. Wright's account underscores the critical breakdowns in communication and coordination between different U.S. agencies that contributed to the success of the 9/11 attacks.

Narrative

Probably the best-written account of the terrorist group’s origins and the nexus of radical personalities at its center, Wright’s Pulitzer Prize-winning account is mostly a painstaking record of bureaucratic failure: Notably, the CIA was aware for more than a year that two of the group’s operatives were in the US — information it delivered to the FBI on Sept. 12, 2001.
