the best option that I have discussed with others is to induce Iranis to convert en-masse to Zoroastrianism (or rather to RETURN to Zoroastrianism). In recent reports the numbers of Zoroastrians has soared to 2 million from 50,000 and there may be millions of hidden, secret Zoroastrians in Iran as many Iranis are truly fed up with Islam which they see as an Arab conspiracy to put down Persia (which if you go to the origins of Islam may very well be true)
Thanks for the information.
