Agreed. We have a good historical example. Torture worked wonderfully well for the Gestapo in France and nearby countries (they actually rolled up and crushed the whole resistance network) until something like 1942 but after that point it didn't work and was pointless. A new resistance movement grew and remained strong. Torture couldn't dent it. The reason for the change was that the Allies (British spymasters really) responded by adopting "cell networks" and properly limited information to a need-to-know basis - something pioneered by the Soviets. Torture works vs a naive opponent network. It doesn't work vs a sophisticated opponent.
