Comment is free: Truth and torture: "one of the extraordinary things about the NKVD was that it hardly ever used techniques that today's White House would disallow.
Prolonged discomfort, cold and sleep deprivation broke almost everyone. Both Conquest and Solzhenitsyn list five main techniques used to break prisoners. All are found among the 'enhanced interrogation techniques' used by the CIA. Stalin's NKVD did not, however, use waterboarding, the technique of simulated drowning which is supposed to be the CIA's most effective technique."
