The phrase "Verschärfte Vernehmung" is German for "enhanced interrogation". Other translations include "intensified interrogation" or "sharpened interrogation". It's a phrase that appears to have been concocted in 1937, to describe a form of torture that would leave no marks, and hence save the embarrassment pre-war Nazi officials were experiencing as their wounded torture victims ended up in court. The methods, as you can see above, are indistinguishable from those described as "enhanced interrogation techniques" by the president. As you can see from the Gestapo memo, moreover, the Nazis were adamant that their "enhanced interrogation techniques" would be carefully restricted and controlled, monitored by an elite professional staff, of the kind recommended by Charles Krauthammer, and strictly reserved for certain categories of prisoner. At least, that was the original plan.
Also: the use of hypothermia, authorized by Bush and Rumsfeld, was initially forbidden. 'Waterboarding" was forbidden too, unlike that authorized by Bush. As time went on, historians have found that all the bureaucratic restrictions were eventually broken or abridged. Once you start torturing, it has a life of its own. The "cold bath" technique - the same as that used by Bush against al-Qahtani in Guantanamo - was, according to professor Darius Rejali of Reed College,

In Norway, we actually have a 1948 court case that weighs whether "enhanced interrogation" using the methods approved by president Bush amounted to torture. The proceedings are fascinating, with specific reference to the hypothermia used in Gitmo, and throughout interrogation centers across the field of conflict. The Nazi defense of the techniques is almost verbatim that of the Bush administration...
Here's a document from Norway's 1948 war-crimes trials detailing the prosecution of Nazis convicted of "enhanced interrogation techniques" in the Second World War. Money quote from the cases of three Germans convicted of war crimes for "enhanced interrogation":

In deciding the degree of punishment, the Court found it decisive that the defendants had inflicted serious physical and mental suffering on their victims, and did not find sufficient reason for a mitigation of the punishment in accordance with the provisions laid down in Art. 5 of the Provisional Decree of 4th May, 1945. The Court came to the conclusion that such acts, even though they were committed with the connivance of superiors in rank or even on their orders, must be regarded and punished as serious war crimes.
