First thing is that terrorist acts are always futile gestures. Terrorists go for symbolic targets, because they have no hope of making tangible gains, and when their attacks are successful, it always unites their adversary, which makes them even stronger than before the attacks.
Second is that the American economy is stronger today than it has ever been, even the Communists like the benefits of a capitalist economy.
