A spade is not a shovel. It's a spade.

American conservatives who seem to think that waterboarding is perfectly ok - and there are, shamefully, many such people including the two leading candidates for the Republican party's presidential nomination and, judging from his equivocation on the subject, the nominee for attorney-general, should be required to read this detailed post from Malcolm Nance.

Mr Nance is no hand-wringer. His bio states, inter alia, that he is:

A 20-year veteran of the US intelligence community's Combating Terrorism program and a six year veteran of the Global War on Terrorism he has extensive field and combat experience as an field intelligence collections operator, an Arabic speaking interrogator and a master Survival, Evasion, Resistance and Escape (SERE) instructor.  From Beirut in 1983 he has deployed on numerous anti-terrorism and counter-terrorism intelligence operations in Balkans, Middle East, sub-Saharan Africa and other small wars in direct support to the principle agencies of the Special Operations and Intelligence Community.  In 1997 at the US Navy SERE School’s Advanced Terrorism, Abduction and Hostage Survival program (ATAHS) in Coronado, California, he created and led the terrorism training team tasked to simulate the Al Qaeda organization and its tactics, techniques and procedures.

The whole post repays reading, but here's some of what he has to say:

The carnival-like he-said, she-said of the legality of Enhanced Interrogation Techniques has become a form of doublespeak worthy of Catch-22. Having been subjected to them all, I know these techniques, if in fact they are actually being used, are not dangerous when applied in training for short periods. However, when performed with even moderate intensity over an extended time on an unsuspecting prisoner – it is torture, without doubt. Couple that with waterboarding and the entire medley not only “shock the conscience” as the statute forbids -it would terrify you. Most people can not stand to watch a high intensity kinetic interrogation. One has to overcome basic human decency to endure watching or causing the effects. The brutality would force you into a personal moral dilemma between humanity and hatred. It would leave you to question the meaning of what it is to be an American...

...Waterboarding is not a simulation. Unless you have been strapped down to the board, have endured the agonizing feeling of the water overpowering your gag reflex, and then feel your throat open and allow pint after pint of water to involuntarily fill your lungs, you will not know the meaning of the word.

Waterboarding is a controlled drowning that, in the American model, occurs under the watch of a doctor, a psychologist, an interrogator and a trained strap-in/strap-out team. It does not simulate drowning, as the lungs are actually filling with water. There is no way to simulate that. The victim is drowning. How much the victim is to drown depends on the desired result (in the form of answers to questions shouted into the victim’s face) and the obstinacy of the subject. A team doctor watches the quantity of water that is ingested and for the physiological signs which show when the drowning effect goes from painful psychological experience, to horrific suffocating punishment to the final death spiral.

Waterboarding is slow motion suffocation with enough time to contemplate the inevitability of black out and expiration –usually the person goes into hysterics on the board. For the uninitiated, it is horrifying to watch and if it goes wrong, it can lead straight to terminal hypoxia. When done right it is controlled death. Its lack of physical scarring allows the victim to recover and be threaten with its use again and again...

... According to the President, this is not a torture, so future torturers in other countries now have an American legal basis to perform the acts. Every hostile intelligence agency and terrorist in the world will consider it a viable tool, which can be used with impunity. It has been turned into perfectly acceptable behavior for information finding.

A torture victim can be made to say anything by an evil nation that does not abide by humanity, morality, treaties or rule of law. Today we are on the verge of becoming that nation. Is it possible that September 11 hurt us so much that we have decided to gladly adopt the tools of KGB, the Khmer Rouge, the Nazi Gestapo, the North Vietnamese, the North Koreans and the Burmese Junta?

What next if the waterboarding on a critical the captive doesn’t work and you have a timetable to stop the “ticking bomb” scenario? Electric shock to the genitals? Taking a pregnant woman and electrocuting the fetus inside her? Executing a captive’s children in front of him? Dropping live people from an airplane over the ocean? It has all been done by governments seeking information. All claimed the same need to stop the ticking bomb. It is not a far leap from torture to murder, especially if the subject is defiant. Are we willing to trade our nation’s soul for tactical intelligence?

Quite so. But apparently - and according to Rudy Giuliani - all this is the creation of the anti-American liberal media who want to see the United States defeated. This moral turpitude might be laughable if it weren't so wicked and, worse, so widespread. This issue alone, I should have thought, ought to make it impossible to endorse either Giuliani or Mitt Romney.
