Osama bin Laden is irrelevant. Dead or alive the Alchlamydia idea is out there like a viral video. The post 9-11 reaction of building the terrorist organisation into some almighty supergroup with complex underground bunkers descending 14 floors down like some sort of Tracey Island and cells operating everywhere ready to rain down fire in any country they wished just made the swine even more attractive to those that feel they need a figurehead in their battles against the great satan, little satan and all their minions.
Every time we announce we've killed a senior commander or terror #2 or such it is like that sorcerers apprentice scene in Fantasia - another mad mop just turns up out of the wreckage.
