Is There Still a Terrorist Threat?

The myth of the omnipresent enemy

Summary: Despite all the ominous warnings of wily terrorists and imminent attacks, there has been neither a successful strike nor a close call in the United States since 9/11. The reasonable -- but rarely heard -- explanation is that there are no terrorists within the United States, and few have the means or the inclination to strike from abroad.

Seem farfetched? Follow the logic:

... Americans are told -- often by the same people who had once predicted imminent attacks -- that the absence of international terrorist strikes in the United States is owed to the protective measures so hastily and expensively put in place after 9/11. But there is a problem with this argument. True, there have been no terrorist incidents in the United States in the last five years. But nor were there any in the five years before the 9/11 attacks, at a time when the United States was doing much less to protect itself. It would take only one or two guys with a gun or an explosive to terrorize vast numbers of people, as the sniper attacks around Washington, D.C., demonstrated in 2002. Accordingly, the government's protective measures would have to be nearly perfect to thwart all such plans. Given the monumental imperfection of the government's response to Hurricane Katrina, and the debacle of FBI and National Security Agency programs to upgrade their computers to better coordinate intelligence information, that explanation seems far-fetched. Moreover, Israel still experiences terrorism even with a far more extensive security apparatus.

Another popular explanation for the fact that there have been no more attacks asserts that the invasion of Afghanistan in 2001, although it never managed to snag bin Laden, severely disrupted al Qaeda and its operations. But this claim is similarly unconvincing. The 2004 train bombings in Madrid were carried out by a tiny group of men who had never been to Afghanistan, much less to any of al Qaeda's training camps. They pulled off a coordinated nonsuicidal attack with 13 remote-controlled bombs, ten of which went off on schedule, killing 191 and injuring more than 1,800. The experience with that attack, as well as with the London bombings of 2005, suggests that, as the former U.S. counterterrorism officials Daniel Benjamin and Steven Simon have noted, for a terrorist attack to succeed, "all that is necessary are the most portable, least detectable tools of the terrorist trade: ideas."
