You are wrong about not having them clarified before. Cong. Rec. S17486-01 (daily ed., Oct. 27, 1990)
President Bush is trying to clarify the definitions for noncombatants. As far as WWII goes,the Japanese internment camps might meet the definition of inhumane and degrading treatment. Today the terms Jap and Kraut might be considered degrading.
Were the internees ever forced to remove their clothes and pile up on each other, naked? Were any of them waterboarded? Were any of them forced to crouch in a corner while a dog barked at him? Were any of them forced to masterbate and photographed while doing so?
