Bin Laden, as medieval ideologist and global terrorist, had a record of accomplishment that was as vast as it was hideous. He did more to slash the fabric of American life than anyone since the Second World War. His capacity to arouse the fevered imaginations of young fundamentalists led to the murder of thousands of men, women, and children—among them Muslim men, women, and children—in Aden, Mogadishu, Nairobi, Dar es Salaam, Washington, New York, Shanksville, Bali, Madrid, London, Baghdad, Kabul, and Marrakech. He provoked wars. He forced the rise of expensive structures of security and surveillance. He incited a national politics of paranoia and retribution. He did as much as the economic rise of China and India has done to undermine America’s short-lived post-Cold War status as a singular, self-confident, seemingly omnipotent superpower.
