If Najibullah Zazi is everything the FBI says he is, then theAfghan-bornDenver airport-shuttle-bus driver represents a new kind of menace for the U.S.. His arrest is a double blessing: it may have thwarted a terrorism plot, and it could give counter terrorism officials a goldmine of information on al-Qaeda, the Taliban and the state of the global jihaD、

It may be weeks before we know if Zazi is indeed a terrorist.Although the FBI believes he and others were plotting to bomb targets in the U.S., Zazi has been charged only with lying to the authorities. He and his father Mohammed have denied involvement in any terrorism plot. The FBI is working to build a stronger case against the pair, and terrorism-related charges are expected imminently.But if it turns out the FBI’s suspicions are accurate, then counter terrorism experts will be especially interested in Zazi—not least because of his origins.
Afghans "have not been a major component of the transnational jihadi network," says KamranBokhari, director of MiddleEast analysis at the intelligence firm Stratfor.Afghan jihadis have tended to join the Taliban, which has traditionally limited its attentions toAfghanistan and northern Pakistan.But Robert Grenier, a formerCI
A、station chief in Pakistan, believes the Taliban’s worldview has changed a great deal since the government it ran was overthrown by the U.S.-led invasion in 2001. "TheAfghan Taliban see themselves quite differently now from 9/11: many of the leaders now see themselves as part of the global jihad," says Grenier, who now heads the consulting firmERG Partners.
So it wouldn’t be a surprise if the Taliban decided to mount a plot against targets in the U.S. "There are probably people in the Taliban who are saying, ’To get rid of the U.S., it’s not enough to fight them here,’" says Lawrence Korb, a national-security expert at theCenter forAmerican Progress.After all, he points out, al-Qaeda’s rationale for attacks on the U.S. was "to get us out of SaudiArabi

Nor is the sentiment restricted to the ranks of the Taliban. "Lots ofAfghans see the U.S. presence as an occupation, and I can easily see how some of them would be motivated to strike at the U.S. wherever they can," Grenier says. Korb points out that there is a great deal of anger amongAfghans over U.S. policies in their country. "There are people who feel we didn’t keep our promises—PresidentBush talked of a Marshall Plan forAfghanistan," he says. "SomeAfghans now wonder if we’re not just like the Soviets."
It’s hard to know if the Taliban has been specifically recruitingAfghans for international operations. If Zazi turns out to be linked to a terrorism plot, he may be no more than "an instrument of opportunity, someone who got in touch with them, who shared their ideology, and whom they thought they could use," saysBokhari.
Apart from Zazi’sAfghan background, counter terrorism experts will be especially keen to know about his associations in Pakistan. The FBI says Zazi has admitted he spent time at an al-Qaeda camp in Pakistan in 2008, receiving training in weapons and explosives. If that is true, then Zazi could be a very valuable source of information on how al-Qaeda trains jihadis now. What U.S. counter terrorism officials know about jihadi training camps is based mostly on intelligence gleaned after al-Qaeda’s.bases inAfghanistan were overrun in 2001. Relatively little is known about the camps in Pakistan, which are located close to the border withAfghanistan.
"If Zazi met or trained with terrorists along theAfghan-Pakistan border, any insights we glean could add considerably to our ever expanding base of knowledge on al-Qaeda or other terrorist groups," says a U.S. counter terrorism official. "That’s a good thing for us and very bad thing for our enemies.\
