Washington - HOW did American interrogation tactics after 9/11 come to include abuse rising to the level of torture? Much has been said about the illegality of these tactics, but the strategic error that led to their adoption has been overlooked.

The Pentagon effectively signed off on a strategy that mimics Red Army methods. But those tactics were not only inhumane, they were ineffective. For Communist interrogators, truth was beside the point: their aim was to force compliance to the point of false confession.

Fearful of future terrorist attacks and frustrated by the slow progress of intelligence-gathering from prisoners at Guantánamo Bay, Pentagon officials turned to the closest thing on their organizational charts to a school for torture. That was a classified program at Fort Bragg, N.C., known as SERE, for Survival, Evasion, Resistance, Escape. Based on studies of North Korean and Vietnamese efforts to break American prisoners, SERE was intended to train American soldiers to resist the abuse they might face in enemy custody.

The Pentagon appears to have flipped SERE's teachings on their head, mining the program not for resistance techniques but for interrogation methods. At a June 2004 briefing, the chief of the United States Southern Command, Gen. James T. Hill, said a team from Guantánamo went "up to our SERE school and developed a list of techniques" for "high-profile, high-value" detainees. General Hill had sent this list -- which included prolonged isolation and sleep deprivation, stress positions, physical assault and the exploitation of detainees' phobias -- to Secretary of Defense Donald Rumsfeld, who approved most of the tactics in December 2002.
