The trouble is letting the enemy define the moral high ground by using deceitful moral equivalency. Sleep deprivation becomes "torture". Opposing ideologies become "phobias". Executing convicted killers becomes "judicial murder". Common sense screening becomes "racial profiling".
If you are willing to "pack it in" rather than to be ill thought of by people who cannot distinguish between distasteful necessity and true evil, then get on with it. Your tender sensibilities are in the way of the defense of civilization.
That isn't my criterion in the least. When I say "torture," I mean the break-out-the-red-hot-pincers treatment. I mean thumbscrews and boiling oil and the boot.
Generally speaking, there are rules to waging war, and if we want to think of ourselves as the good guys we should follow them. Simple survival is the goal of animals and DUers, and we are better than that. We are civilized.
Our pilots that were shot down over North Vietnam endured incredible torture. The North Vietnamese could break any of them and did. The code of the pilots was to resist up to the point they thought they would be killed. Some of our brave men resisted past that point and were tortured to death. They were able to break them and get information. They were not able to "turn them" against out great nation.
Torture applied correctly does work.
