Into Thin Air

Till this life is over and doomsday comes.

It ' s the root and trunk of destruction,

It ' s the evil on the branches of trees.

"The only thing that seems to rile him up is mention of America," says al Bahri. "I think from the very beginning of his childhood he hated America. I don't know why. He won't even drink a Pepsi."

Bin Laden's No. 2, Zawahiri, is just as baleful toward the United States. According to various accounts, it was Zawahiri, a well-educated Egyptian doctor, who before 9/11 persuaded bin Laden to turn his terrorist ambitions from the "near enemy" (the corrupt regimes of Saudi Arabia, Jordan and Egypt) to the "far enemy" (the United States). Zawahiri may represent more of a threat to the West than bin Laden. By taking himself off the grid, bin Laden may no longer be in operational control; capturing him might be more symbolic than significant. But meanwhile Zawahiri has become more visible. "In the past two years he has put out more than 30 messages," says Rita Katz, director and founder of the SITE Institute, which monitors jihadist Web sites. She notes that within hours of the storming of the Red Mosque by Pakistani forces, Zawahiri's response was uploaded on the Internet. "I believe he's in or near an urban area where he is able to get news and respond to issues quickly," says Katz. "In 2005, you'd still see videos with cheap fabric backdrops that rippled in the wind. Today, they seem to be using better equipment, complete with artificial backgrounds added postproduction." "Al Qaeda may have seventh-century ideas, but they have 21st-century acumen for communications," says Georgetown University terrorism expert Bruce Hoffman. "Al Qaeda has become a world brand and their videos are the juice that fueled that recognition."

The overarching question is whether Al Qaeda has the ability to strike the United States with another "spectacular" along the lines of 9/11, or possibly something worse. When the Qaeda leadership was driven into the hills in 2001, and many of their top operators were killed or captured, the jihadist movement was sustained by local wannabes. They set off bombs and blew up subways and discos from Indonesia to Britain. But they were not very high-tech, and some were klutzes, like the two mokes who last June failed to set off a pair of car bombs in London and then tried, unsuccessfully, to become suicide bombers at the Glasgow airport. (One eventually did die of his burns, but no civilians were injured when their car caught fire but failed to explode.)
