Oooh! I'm scared I'm going to drown in the bathtub!

As John Tierney writes,

John Mueller has an awkward question for those of us in the terrorism industry, which is his term for the journalists, politicians, bureaucrats and assorted "risk entrepreneurs" who have alarmed America about terrorism.

John Mueller wonders Is There Still a Terrorist Threat?

...it is worth remembering that the total number of people killed since 9/11 by al Qaeda or al Qaeda­like operatives outside of Afghanistan and Iraq is not much higher than the number who drown in bathtubs in the United States in a single year, and that the lifetime chance of an American being killed by international terrorism is about one in 80,000 -- about the same chance of being killed by a comet or a meteor. Even if there were a 9/11-scale attack every three months for the next five years, the likelihood that an individual American would number among the dead would be two hundredths of a percent (or one in 5,000).

Although it remains heretical to say so, the evidence so far suggests that fears of the omnipotent terrorist -- reminiscent of those inspired by images of the 20-foot-tall Japanese after Pearl Harbor or the 20-foot-tall Communists at various points in the Cold War (particularly after Sputnik) -- may have been overblown, the threat presented within the United States by al Qaeda greatly exaggerated. The massive and expensive homeland security apparatus erected since 9/11 may be persecuting some, spying on many, inconveniencing most, and taxing all to defend the United States against an enemy that scarcely exists.
