Der Spiegel on the 9/11 Hijackers

There's a very good article on the English-language site of the German newsmagazine Der Spiegel that reports on some of the additional details about the 9/11 plot that have been learned from the interrogations of captured al-Qaeda figures: Operation Holy Tuesday.

To the investigators, it is now apparent that the apocalypse in New
York only became possible because three threads gradually converged in the
mountains of Kandahar [in Afghanistan]. The first thread was the obsession of
Sheik Mohammed's clan, the members of which deeply detest the United States. The
second was the power that [the] fanatic Osama Bin Laden held over an entire army
of religious fanatics with paramilitary training. The third and final thread was
the blind willingness to become martyrs within a group of Muslims from
Hamburg-Harburg [in Germany], men who wanted nothing more fervently than to die
in the war against the infidels.

We're going to be living in some form with terrorism from Islamic extremists for a long time. Material like this that gives investigators insight into both the personal and organizational processes going on will be very important in coming to grips with it.
