Perhaps. Any links to studies?
No studies. Just 50 years of historical documentation I have read over the years, and first hand accounts from my father and older friends of mine who served in previous wars. There are things being lumped in with "torture" that simply are not torture, and the willingness to call them such is obscene. Don't need a case study to show that denying sleep, minimal amounts of food and water, loud music, barking dogs, etc, is not torture. It's common sense in a time of war. If it was my butt on the line in a war, I would hope my friends would do those things to minimize the threat out in the field. I still suggest that people so opposed to any kind of psychological or mild physical techniques, have never had their butt on the line, or that of a loved one.
