What threat? And what are Jafarzadeh's qualifications? I get suspicious about alot of Iranian dissidents because the most powerful of em have links to the Shah. Does Iran REALLY need him back?! Every credible study I've seen indicates Iran is at least 7-10 years away from nukes. And as even Ron Paul says, Israel can damn take care of itself with its (also illegal and undeclared) 200+ nukes, most of which are probably pointed at Iran and Syria these days anyway. Impeach!
