I guess the hawks are getting desperate to attack Iran. The bit I like is the tie-in with one of the Mexican drug gangs which the DoJ has been caught shipping weapons to, some of which have been used to kill US cops and border guards (look up 'Operation Fast and Furious').
Leaving aside the 'pot calling the kettle black' aspect - Obama claims a right to assassinate American citizens in foreign countries - Iran has no reason to get involved in such a crack-pot conspiracy. That's not to say they're a great bunch of guys, but they're not crazy.
