Establishing the baseline state is important to demonstrate to the HVD that he has no control over basic human needs. The baseline state also creates in the detainee a mindset in which he learns to perceive and value his personal welfare, comfort, and immediate needs more than the information he is protecting. The use of conditioning techniques do not generally bring immediate results; rather, it is the cumulative effect of these techniques, used over time and in combination with other interrogation techniques and intelligence exploitation methods, which achieve interrogation objectives. These conditioning techniques require little to no physical interaction between the detainee and the interrogator. The specific interrogation techniques are:
a. Nudity. The HVD’s clothes are taken and he remains nude until the interrogators provide clothes to him.
–CIA memo describing combined interrogation techniques, December 30, 2004
I have often thought that one of the problems with our obsessive focus on waterboarding was that we may have inadvertently legitimized all the other torture techniques they used. It's a common problem in advocacy --- you focus on the worst because it's the thing that will instantly convey the horror of the practice, but in the process you normalize lesser horrors that are just as wrong. It's a problem for which I have no solution. It happens all the time.
The case of Bradley Manning may be illustrative of that. He's been held, without charges, under punitive conditions that mirror in some respects the treatment of terrorist suspect detainees in the nation's foreign prison camps. However, he isn't being waterboarded, so there is resistance to the idea that this is torture. But it is:
“Removal of clothing was authorized by the Secretary of Defense
for use at GTMO on December 2, 2002,” acknowledges the recently released U.S. Senate Armed Service Committee report on the use of harsh interrogation techniques. It also reports that the use of prolonged nudity proved so effective that, in January 2003, it was approved for use in Afghanistan and, in the fall of 2003, was adopted for use in Iraq.“Inquiry into the Treatment of Detainees in U.S. Custody”
The Senate report came out shortly after a secret International Committee of the Red Cross (ICRC) report on CIA torture techniques used as part of its detention program was leaked by Mark Danner of the “New York Review of Books.” These reports provoked a storm of media attention, much of it focused on the use of waterboarding (or what the ICRC more aptly calls “suffocation by water”) and, in particular, its use on Khalid Sheikh Mohammed 183 times and Abu Zubaydah 83 times.
