Last week, RAND Corp. published a study looking at homegrown jihadi terrorism. Of the 32 "plots" uncovered in the U.S. since 9/11, "only 10 developed anything resembling an operational plan that identified a specific target, developed the means of attack, and offered a sequence of steps to carry [it] out." "Of these, six were Federal Bureau of Investigation stings" involving fake bombs -- "on their own, only two individuals actually attempted to build devices. One was arrested while doing so, and the other's device failed."
The RAND report sums up: "Thus far, despite al Qaeda's intensive online recruiting campaign, their numbers remain small, their determination limp, and their competence poor."
In May 2010, after the Times Square bomber's jerry-rigged contraption of gas cans, firecrackers and fertilizer ruined his Pathfinder's upholstery, Attorney General Eric Holder proclaimed "the most dangerous impression we can draw is that this threat no longer exists."
But by convincing ourselves that the threat is "existential," we've wasted trillions and built a surveillance state that refuses to recede with the waning al Qaeda threat. Complacency can be dangerous, but it's hardly the only danger.
