Torture is an emotionally charged word, especially when it is used to further one’s political ends. One person’s torture is another person’s useful tool.
What we are talking about is how far we are willing to go and with what tools available in our kit are we willing to use on hard cases to obtain vital information for our survival. Therefore, the end result is intelligence of reliable quality to act upon. Tools used in a battlefield situation will be different than tools used to obtain intelligence of a strategic value.
It has been shown that use of sadistic torture, like pulling nails, electric shock, and other means of causing pain is counterproductive and will produce information that may be useless. The subject will say anything to get the pain to stop.
So the interrogator is going to have to to get inside the head of the subject and take the subject on a psychological journey that will strip away the subject’s defenses. How deep one has to go depends on the subject and the value placed on the intelligence. The islamic hardcases, by nature of their beliefs and their training, can be very tough nuts to crack. So the interrogator has to look into his toolkit and see what would be an APPROPRIATE method to use, and put it to work.
The stakes are high. Our survival as a nation and civilization are what’s on the line. We are at war, and we need the intelligence. People who use interrogation techniques and the T word to beat govt agencies on the head are not talking about humane behavior. They are playing politics. War is settling disputes when everything else has failed. War is about breaking things and killing people. And the gathering of intelligence by interrogation, using appropriate techniques, is part of war.
