Ghost Wars: The Secret History of the CIA, Afghanistan & Bin Laden from the Soviet Invasion to September 10, 2001

A few—like the four men who arrived secretly in Kandahar in the autumn of 1999: Atta, Jarrah, al-Shehhi, and Binalshibh—carried passports and visas that facilitated travel to Europe and the United States. These relatively elite volunteers moved like self-propelled shooting stars through al Qaeda’s global constellation. Their reasons to join were as diverse as their transnational biographies. In many ways they retraced the trails of radicalization followed in the early 1990s by Ramzi Yousef and Mir Amal Kasi. They were mainly intelligent, well-educated men from ambitious, prosperous families. They migrated to Europe, studied demanding technical subjects, and attempted—unsuccessfully—to establish themselves as modern professionals far from the family embrace and conservative Islamic culture they had known in their youths. As they joined a violent movement led by the alienated, itinerant son of a Saudi construction magnate and a disputatious, ostracized Egyptian doctor, they pledged their loyalty to men strikingly like themselves.
