I don't believe there is such a thing as a moderate Islamist party. The challenge with Islamists is that they seek to impose what they call Sharia on everybody, Muslim and non-Muslim alike.
I wouldn't even know - and I spent three years in the CIA - I wouldn't even know how you'd start a covert action program in a place like Iran. It would be extraordinarily difficult.
Beside all this I think there was something personal, being Muslim myself who lived in the west I felt that it was my obligation my duty to tell the truth about Islam. It is a religion that has a 700 million following, yet it's so little known about it which surprised me.
