Intelligence officials believe the recent spate of Iranian attacks has been carried out by the Quds Force's Unit 400, which runs special overseas operations.
>>>There is no doubt that several recent attempt at terrorist attack around the world were arranged by AL Qud and required Khamenei's approval. Also Khamenei is famous for shortightednes in his strategic choices both domestically (the 2009 fiasco) and abroad where--even as the regime bemoans its worldwide pariah status it engages in (or attempts) repeated covert schemes that reinforce mistrust and detetestation of the regime that seems capable of anything.
On the other hand, the above report may be an attempt by anonymous (neo cons? hard line factions in Israel?) to exploit Khamenei' stupidity by taking it a step further. It is likely that Khamenei's covert destabilization and terror schemes will continue simply because the guy is so boneheaded he can't anticipate the negative repercusion. However, whether he has the capacity to accelerate such attacks--and the potential consequeness of getting caught-I'm not so sure.
