The latest Bloomberg Businessweek features a cover story that explores “Why Bin Laden Lost.” You could quit reading after the first two paragraphs:

That’s it. There’s a curious lack of ambition in those words. The United States was not founded for the greater glory of anything, or as the necessary outcome of history, but for the freedom to collect figurines, to join a clogging troupe, to take a road trip.
