Um... which book were you reading? My copy has the conspiracy primarily headed by Islamic terrorists, with technical assistance from Soviet-era holdout East Germans, and stateside assistance from an "American Indian Movement" type. Not a single neo-Nazi to be found anywhere...
The book I read was NOT, not the one with Ben Affleck and Morgan Freeman on the cover, the book based on the movie screnplay (btw, that version also has the USSR still existing--although it is post breakup in the movie), it was still neo-nazis in it. Unless its an oddball edit--in some books that have been reprinted have editing of charachters, etc..)
