As for this alleged CBS program on Rafsanjani on 60 minutes (saw on peiknet.com, hoder.com): Iran is really not THAT important in world affairs, that the Expediency Council leader would have a program on him in America. Not many people know who Rafsanjani is outside Iran, believe it or not. Of course he is rich by Iranian standards, but not enough by world standards to be in the billionaires' list.
So an American program said to be investigating his wealth is just some Iranian's fantasy.
60 Minutes only interviewed him in 1997 because he was the president. Now, it is true, he is still one of the three most powerful men in Iran, but I don't think American viewers are going to be interested enough to sit through a program on him.
