Victim, Player, Perpetrator
Now comes the U.S. Senate to tell us what had already become clear: abuse of prisoners in Iraq, Afghanistan, and Cuba came from the top: a memo signed by President Bush in February, 2002, declaring that Al Qaeda and Taliban taken captive were not eligible for the protections of the Geneva Convention. (It's odd, then - if not infuriating - to see the headline on the linked article, "Rumsfeld Responsible for Torture." What exactly does the phrase "commander in chief" mean?)
The dark humor in all this is the source of the techniques: the military turned to Survival, Evasion, Resistance, and Escape (SERE) school instructors to learn waterboarding and other techniques. The Air Force created SERE after the Korean War, to offer its aircrews real training in case of being taken prisoner; the program later expanded to include Navy and Air Force aircrews.
I went through SERE training in 1984 in the desert east of San Diego. It involved plenty of sleep deprivation and some mild violence; shaking, banging off walls, but mostly empty threats (they were not, after all, really going to purposely injure a US military officer). Nobody in my group got waterboarded, but we heard plenty of detailed stories about how it worked. What's amazing to me is the circular nature of the torture program: we developed SERE to help our people resist torture; the SERE program involved people pretending to be torturers and pretending to be tortured, and now we've taken that play-acting and used it for real. We've gone from the victims, to players, to perpetrators.
I like General Petraeus's simple summation of what should make us the good guys: "Adherence to our values distinguishes us from our enemy."
