It's interesting that the spying and the Bostom bombings are mentioned in one breath. How come all that spying did not identify the bombers before the attack?

It's interesting that the spying and the Bostom bombings are mentioned in one breath. How come all that spying did not identify the bombers before the attack? With the current foreign policies terrorist attacks are as inevitable as car accidents (albeit far less dangerous). We accepted car accidents (I do not see a war on driving). And since foreign policy remains largely unchanged it seems we have accepted terrorism as well. The terrorists have achieved their goal anyway. They instilled fear in the US populous, and set us all on a path to willingly give away our liberties. We should look at Norway, which kept its cool after the 2011 attacks; that is strong, confident reaction. Ours is one of cowardice; with lemmings like Hayden repeating the party line ad nauseum.
