There is a level of doubt that has risen purely from the foreign policy of the mullahs, and their sense of world order. In the time of the Shah, the US did not mind even if Iran had the bomb. So it is the type of people that are running the country that matters. We have a lot of intelligent people in Iran and outside, who can represent Iran, and do not have wacko 7th Century ideas.
The question you need to be asking is, why did a modern state in 1979 get derailed by Carter. What was he worried about when he said Iran is an Island of Stability. Obviously that is exactly what he did not want. Just think what Iran would be now. Quo Bene?
It is very simple.
