Osama bin Laden, who was killed in Pakistan on Sunday, was a son of the Saudi elite whose radical, violent campaign to recreate a seventh-century Muslim empire redefined the threat of terrorism for the 21st century.
With the attacks on the World Trade Center and the Pentagon on Sept. 11, 2001, Bin Laden was elevated to the realm of evil in the American imagination once reserved for dictators like Hitler and Stalin. He was a new national enemy, his face on wanted posters, gloating on videotapes, taunting the United States and Western civilization.
