One of the great problems with the word "torture" is that it tolerates no ambiguity. It is a taboo word, like racism or incest. Once you call something torture, the conversation is supposed to end. It's a line no one may cross. As a result, if you think the enhanced interrogation techniques are necessary, or simply justified, you have to call them something else. Similarly, many sincere opponents of these techniques think that if they can simply call them "torture," their work is done.
