Jeffrey Goldberg (who is writing some of the most thoughtful and informed commentary about the Israel-Hamas conflict on his blog and in The New York Times) nails it:
Bob Woodward reports today that a senior Bush Administration official has concluded that a Saudi national, the so-called 20th hijacker, was tortured at Guantanamo. Once, a few years ago, an Egyptian friend wrote to me despondent over the fact that America practiced torture. “You have to be better than us. That is how you’ll win,” he said. Torturing people is a way to convince Arabs living under authoritarian regimes that we’re no better than their own corrupt rulers. God willing, it will soon stop.
