Mughals from Iran. Also Aryans from Iran. I think Iran has a habit of invading Hind. But then the name Hind or Hindustan is also Iranian. Does that make us all Iranis by descent?? Coming back to current times. Iran currently is the largest producer of gas in the world and the second largest producer of crude oil in the world. They have reserves not only on the Persian Gulf side but also the Caspian region. Plus their political clout in the Middle East is so great specially in the oil producing areas, that messing with Iran would be a big mistake. America has already attacked Iran, through Iraq in the 80's and we all know the result of that warfare. Saddam was lent nearly $30 billion by America through Saudi & Kuwaiti channels and still Iran is intact and Saddam is no where. Dont under estimate them. They are very friendly with India and that is India's luck. But they have already shown the world that even thinking about attacking them can send the world into turmoil (Oil prices have trebled in the last 8 months). As of the moment Americans are trying to woo Iran and they desperately wanted negotiations last week. We will see a surge in American endeavours in the coming times. Iran - India pipeline is as necessary for India as is the nuclear deal. Both are India's right and we shall have it. No matter who is upset. We will ultimately be paying for both from our pockets.
