According to the Irani opposition leader Karoubi the Revolutionary Guard profits enormously profits from the sanctions:
Opposition leader Mehdi Karroubi has said Iran's elite Revolutionary Guards back sanctions against Tehran as they make "astronomical profits" from the punitive measures, a website said on Sunday.
"I believe that part of the Iranian rule as well as the Revolutionary Guards are in favour of sanctions as they make gigantic and astronomical profits from them," Karroubi was quoted as saying on opposition website Rahesabz.net.
The Guards regularly shrug off international sanctions imposed on Iran for its defiant nuclear programme, with some top commanders expressing willingness to take on projects abandoned by Western companies, including in the energy sector.
Just like with Saddam; just like with Milosevic. Sanctions are opium to make the public in the West feel good. If you really want to make a difference you need to highlight information that is negative for the regime, like corruption and incompetence.
