"Dr. Allen Keller, the director of the Bellevue Hospital/New York University Program for Survivors of Torture, has treated a number of people who had been subjected to forms of near-asphyxiation, including waterboarding. In an interview for The New Yorker, he argued that "it was indeed torture. 'Some victims were still traumatized years later', he said. One patient couldn't take showers, and panicked when it rained. 'The fear of being killed is a terrifying experience', he said". Keller also gave a full description in 2007 in testimony before the U.S. Senate Select Committee on Intelligence on the practice." (Keller, Allen S. (25 September 2007). "Water-boarding". Statement by Allen S. Keller at the Hearing on U.S. Interrogation Policy and Executive Order 13440. United States Senate Select Committee on Intelligence. )
"Waterboarding was designated as illegal by U.S. generals in the Vietnam War. On 21 January 1968, The Washington Post published a front-page photograph of two U.S soldiers and one South Vietnamese soldier participating in the waterboarding of a North Vietnamese POW near Da Nang. The photograph led to the soldier being court-martialled by a U.S. military court within one month of its publication, and he was dishonorably discharged from the army." (Pincus, Walter (5 October 2006). "Waterboarding Historically Controversial". The Washington Post. p. A17)
The US Army thought the practice was so unethical, immoral, and illegal, that they cashiered the man caught doing it.
It's hard to believe those in this thread claiming "superior" knowledge based on"superior" service were unaware of this. Maybe that "superior" service was not all that superior.
