Christopher Hitchens, a writer for Vanity Fair magazine, underwent waterboarding to experience it for himself firsthand.

What more can be added to the debate over U.S. interrogation methods, and whether waterboarding is torture? Try firsthand experience. The author undergoes the controversial drowning technique, at the hands of men who once trained American soldiers to resist--not inflict--it.

Believe Me, It's Torture

Here is the most chilling way I can find of stating the matter. Until recently, "waterboarding" was something that Americans did to other Americans. It was inflicted, and endured, by those members of the Special Forces who underwent the advanced form of training known as sere (Survival, Evasion, Resistance, Escape). In these harsh exercises, brave men and women were introduced to the sorts of barbarism that they might expect to meet at the hands of a lawless foe who disregarded the Geneva Conventions. But it was something that Americans were being trained to resist, not to inflict. More here.

It was done in your name. Should the United States employ waterboarding as an aid in the interrogation of suspects?
