According to an expert, Malcolm Nance:

Once at SERE and tasked to rewrite the Navy SERE program for the first time since the Vietnam War, we incorporated interrogation and torture techniques from the Middle East, Latin America and South Asia into the curriculum. In the process, I studied hundreds of classified written reports, dozens of personal memoirs of American captives from the French-Indian Wars and the American Revolution to the Argentinean ‘Dirty War’ and Bosnia. There were endless hours of videotaped debriefings from World War Two, Korea, Vietnam and Gulf War POWs and interrogators. I devoured the hundreds of pages of debriefs and video reports including those of then Commander John McCain, Colonel Nick Rowe, Lt. Dieter Dengler and Admiral James Stockdale, the former Senior Ranking Officer of the Hanoi Hilton. All of them had been tortured by the Vietnamese, Pathet Lao or Cambodians. The minutiae of North Vietnamese torture techniques was discussed with our staff advisor and former Hanoi Hilton POW Doug Hegdahl as well as discussions with Admiral Stockdale himself. The waterboard was clearly one of the tools dictators and totalitarian regimes preferred.

Why does Dick Cheney suggest that waterboarding is not torture?

Nance does not mix words on the subject:

There is No Debate Except for Torture Apologists

1. Waterboarding is a torture technique. Period. There is no way to gloss over it or sugarcoat it. It has no justification outside of its limited role as a training demonstrator. Our service members have to learn that the will to survive requires them accept and understand that they may be subjected to torture, but that America is better than its enemies and it is one’s duty to trust in your nation and God, endure the hardships and return home with honor.

End of discussion, or will Mukasey be confirmed?
