I don't think Scotty knows and I'm not aware that he said there are none. Whether there are is secondary to the Saudis being the prime problem. W apparently believes Iraq is one tenacle of that Saudi 'octopus' and needs to be chopped off as was Afganistan, and I can support that.
IMO, Scotty's thinking runs along the line of Buchanan/Scrocroft and they have a legitimate argument. Jumping on Scotty begs the question, and applying 'triple' punishment based on indoendo is not what America is about.
