Foreign Affairs - Is There Still a Terrorist Threat? - John Mueller:

"On the first page of its founding manifesto, the massively funded Department of Homeland Security intones, "Today's terrorists can strike at any place, at any time, and with virtually any weapon."

But if it is so easy to pull off an attack and if terrorists are so demonically competent, why have they not done it? Why have they not been sniping at people in shopping centers, collapsing tunnels, poisoning the food supply, cutting electrical lines, derailing trains, blowing up oil pipelines, causing massive traffic jams, or exploiting the countless other vulnerabilities that, according to security experts, could so easily be exploited?

One reasonable explanation is that almost no terrorists exist in the United States and few have the means or the inclination to strike from abroad. But this explanation is rarely offered."
