One of the things ANTPogo said is "Those techniques were considered good enough to protect us during a shooting conflict (and potential nuclear war) with the "Evil Empire" itself, after all."
But that situation was far different from the current one. We didn't rely on intel or interrogation to prevent a nuclear attack on the United States, like we must where terrorism is concerned. We relied on deterrence and the threat that we would utterly annihilate with nuclear weapons any country that attacked us with them. The US was prepared to absorb a nuclear attack so we could be sure that one was underway. That's why so much money and effort went into making sure our arsenal was survivable against a full scale nuclear attack by our largest rival. That, not intel, was why this country was never attacked by the "Evil Empire". Nuclear war was at any level was not acceptable unless it was to be for all the marbles. MAD. A policy that worked very well for many decades.
But terrorism is different. It will come in a form that we simply cannot afford to "ride out". Doing so could potentially cost hundreds of thousands or even millions of lives. That is not acceptable. And after the attack, we might not know with any certainty how to effectively retaliate ... who to retaliate against ... how to prevent the next attack? Except by doing what we are now doing; ie., trying to wage an information war against terrorism and find out about plots before they mature. That was the lesson of 9/11. I hope the current Administration hasn't forgotten that lesson but I'm beginning to have my doubts.
