Even the Iranians aren't this stupid. The eagerness by the US government to pin this onto the government suggests that its a setup to simply reaffirm links with Saudi and as a bonus, set a prelude for further sanctions against Iran. As mush I would like to see Iran get a more moderate government, i believe that if this story is a .setup then it only strengthen the madinnerjacket crew and their Iranian government. PS if they wanted tp target a Saudi national then all they have to do is carry out a rip across the border. Why bother going to the US?
