All this confirms information that I and others have described publicly. But just as the memo begins to describe previously undisclosed details of what enhanced interrogations achieved, the page is almost entirely blacked out. The Obama administration released pages of unredacted classified information on the techniques used to question captured terrorist leaders but pulled out its black marker when it came to the details of what those interrogations achieved…

Critics claim that enhanced techniques do not produce good intelligence because people will say anything to get the techniques to stop. But the memos note that, “as Abu Zubaydah himself explained with respect to enhanced techniques, ‘brothers who are captured and interrogated are permitted by Allah to provide information when they believe they have reached the limit of their ability to withhold it in the face of psychological and physical hardship.” In other words, the terrorists are called by their faith to resist as far as they can — and once they have done so, they are free to tell everything they know. This is because of their belief that “Islam will ultimately dominate the world and that this victory is inevitable.” The job of the interrogator is to safely help the terrorist do his duty to Allah, so he then feels liberated to speak freely.

This is the secret to the program’s success. And the Obama administration’s decision to share this secret with the terrorists threatens our national security.
