Weapons of Mass Destruction

The Moussaoui jurors were instructed [Reuters] that a plane qualifies as a weapon of mass destruction when used as a missle.

This means that a missle is a weapon of mass destruction,
and that a plane is dual use technology.

The impact of this line of reasoning on the size of the threat from weapons of mass destruction has not yet been outlined. Presumably, any country with box cutters could be considered to have a program to acquire weapons of mass destruction, if, in addition to the box cutters, we have reason to believe that they are bad people.
