Emerson: The rage against the United States is increasing. In an environment that not only sanctions terrorism but mandates terrorist attacks against "enemies" of Islam, the question is how long the quiet can remain.- Emerson: Not at all. If anything, the threat is greater now than before the World Trade Center bombing as the numbers of these groups and their members expands. In fact, I would say that the infrastructure now exists to carry off twenty simultaneous World Trade Center-type bombings across the United States. And as chemical, biological, and even nuclear weapons become available to them, the threat becomes ever more ominous. Just because someone holding a gun to your head doesn't pull the trigger should not be understood as the threat not existing. It would be suicidal to permit our national security to depend on the good will or rationality of radical fundamentalists.
