“But I find it suprising that if they hurt you so much that you compare the USA to them” No. I don’t compare the US with the Nazi. What I said is there is a danger, if you use the same methods, to be compared with the Nazi. It give to your enemy a good weapon. Something else: the British didn’t use tortures during WW”. MI5 said that under tortures (or extreme interrogation techniques) every body talk. The only problem is you don’t know if it is true.
I experimented a long pain. Nothing compared to torture. Believe me I would have denounced all the Yellow Page books to stop it…
The French Resistance Hero, Pierre Brossolette preferred to jump from the 3rd floor (and with him 2 SS) instead to be tortured. What you thing as benign because it is no physically harming is not. Just try to stop to sleep during two days. And imagine doing so under fear.
One of the favourite tortures of the Japanese on the allies prisoners forced to build the railways (Kwai River) was to oblige them to lift a heavy stone over their head, and to slap them when they started to fail. According to your definition, it isn’t torture. Except in extreme cases the prisoners wasn’t harm. The survivors didn’t get permanent harm. However, I think it was torture.
