This blog has an occasional series on "Vizzini" moments. Thanks to YouTube, we can now explain it through a brief video mash-up:

In the days immediately after the attacks of Sept. 11, 2001, members of President Bush’s war cabinet declared that it would be impossible to deter the most fervent extremists from carrying out even more deadly terrorist missions with biological, chemical or nuclear weapons.

Since then, however, administration, military and intelligence officials assigned to counterterrorism have begun to change their view. After piecing together a more nuanced portrait of terrorist organizations, they say there is reason to believe that a combination of efforts could in fact establish something akin to the posture of deterrence, the strategy that helped protect the United States from a Soviet nuclear attack during the cold war.

Interviews with more than two dozen senior officials involved in the effort provided the outlines of previously unreported missions to mute Al Qaeda’s message, turn the jihadi movement’s own weaknesses against it and illuminate Al Qaeda’s errors whenever possible.

A primary focus has become cyberspace, which is the global safe haven of terrorist networks. To counter efforts by terrorists to plot attacks, raise money and recruit new members on the Internet, the government has mounted a secret campaign to plant bogus e-mail messages and Web site postings, with the intent to sow confusion, dissent and distrust among militant organizations, officials confirm.

It's good stuff. But it's not "deterrence" in the Cold War sense of the word.

Successful deterrence of Al Qaeda would be taking place if the organization decided not to take action because they feared retaliation by the United States against assets that they held dear. Deterrence works if an actor refrains from attack because they calculate that the cost of the adversary's response would outweigh any benefit from the initial strike.

But that's not in the U.S. strategy. Instead, what U.S. officials appears to be doing is decreasing the likelihood of a successful attack -- by sowing confuson, interdicting logistical support, and reducing sympathy for the organization. The closest one could come to deterrence is if one defined Al Qaeda's reputation as a tangible asset that would face devastating consequences after a successful attack. Even here, however, the U.S. strategy is primarily to weaken Al Qaeda by increasing the odds of an unsuccessful attack.

The more appropriate word to use here is "containment." The United States is trying to sow divisions within the jihadi movement -- much like Kennan urged the United States to do among communists of different nationalities. The United States is applying counter-pressure in areas where Al Qaeda is trying to gain supporters and symathizers -- much like Kennan urged the application of "counter-force" in areas where the Soviets tried to advance their interests.

This is all to the good. But it's not deterrence. Indeed, this is one of those rare moments when the headline -- "U.S. Adapts Cold-War Idea to Fight Terrorists" -- is more accurate than the lead of the story.
