But, sometimes even moral people do nasty things to survive.
That's not the case here. Try again.
People have been tortured here for SHORT-TERM reasons, not for reasons of survival. They have been tortured to avoid individual terrorist attacks, not to prevent things that threaten our survival.
I doubt that it's been successful even at that, but for the sake of argument, let's say that torture prevented some attack that would have killed a few hundred or a thousand people, something like another 9/11.
That is short-term, and unrelated to our survival.
The more important question is the long-term question, the one related to our survival: How do we stop these attacks overall, rather than individually? How do we get back to a world in which we are not under this constant threat?
The answer is we need to reach a political understanding with the average person in the Middle East, we need that average person to be generally on our side, and generally against the terrorists.
Torturing people is counter-productive towards the long-term goal and as a result is itself a threat to our survival.
