The point isn't that there are no enemies. The point is that the cure is worse than the sickness.
Anyway, what are you worrying about? Another 9/11? Car accidents are more probable causes of death, and you could eliminate most of them cheaper and with no ethical issues, boosting economy as a byproduct (build fast railroads, subsidize the tickets). Gun ownership is another low hanging fruit. Hell, even just making flying cheaper and more accessible will probably save more lives than NSA.
