Zoroastrianism doesn't really have anything to do with India - other than Iranians fled Arab persecution to seek refuge there after the Muslim invasion in 600 A.D. It may be the key to helping remove the radicals in controlling Iran because they are so far out of touch with their history and culture.
Zoroastrianism is a religion that developed in Iran from about the sixth century BC, generally ascribed to Zoroaster (Zarathustra), who was born in Iran '258 years before Alexander.' The date of Zoroaster's birth has been given variously as 6000 BC, 1400 BC, and 1000 BC, but Herzfeld accepts the traditional date, approximately, as now confirmed (Herzfeld, (570 - 500 BC); Jackson, 660 - 583 BC). Accordingly, Zoroaster was contemporary with other great religious personages, including Buddha, Confucius, Lao Tze, and several Hebrew prophets. That Zoroaster used Vedic materials found in early Hinduism can hardly be denied; that he was a polytheist like Darius, Xerxes, and others who were probably Zoroastrians (at least, their inscriptions pay homage to Ahura Mazda) seems most likely.
As the Iranian people just found out. Nothing will rid Iran of the Islamofascist but force. They are like a plague of locast.
