David Ignatius:

President Obama promised CIA officers that they won't be prosecuted for carrying out lawful orders, but the people on the firing line don't believe him. They think the memos have opened a new season of investigation and retribution.

The lesson for younger officers is obvious: Keep your head down. Duck the assignments that carry political risk. Stay away from a counterterrorism program that has become a career hazard.

Would you care for a little hogwash with that?

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.

Apparently waterboarding is about catharsis for the captive.

While Sept. 11 was frightening enough, there were ample fears that al Qaeda had secured a “suitcase bomb” and that a nuclear attack on a major U.S. city could come at any moment. For individuals, such an attack was simply another possibility. For the government, however, the problem was having scraps of intelligence indicating that al Qaeda might have a nuclear weapon, but not having any way of telling whether those scraps had any value.

This lack of intelligence led directly to the most extreme fears, which in turn led to extreme measures. A lack of knowledge forces people to think of worst-case scenarios.

Collecting intelligence rapidly became the highest national priority. Given the genuine and reasonable fears, no action in pursuit of intelligence was out of the question, so long as it promised quick answers. This led to the authorization of torture, among other things. Torture offered a rapid means to accumulate intelligence, or at least — given the time lag on other means — it was something that had to be tried.

It should surprise no one that Human Rights Watch can write a persuasive anti-torture op-ed. However, as is often the case, there is more news in what's not in the papers than in what does appear. And what I don't see right now are op-eds from DNI Negroponte and DCI Hayden and the DDO telling us in no uncertain terms how essential these abusive practices are to their operational success.
