Iran was on the threshold of becoming a nuclear state when the Iran nuclear deal or more specifically the joint comprehensive plan for action between Iran and world powers like United States and European Union potentially altered that course and at the very least delayed that possibility by 10 or 15 years. It is the comprehensive agreement according to which Iran has agreed to redesign, convert and significantly reduce its nuclear capabilities in order to lift all nuclear related economic sanctions imposed on it. But Israels hardline Prime Minister Benjamin Netanyahu called it a stunning historic mistake and Mr Netanyahu is not alone among the critics of Iran. He enjoys common ground for a change with even Saudi Arabia since both them blame Iran for sponsoring militias that challenge Israel in Lebanon and Saudis in Yemen. Besides there is no guarantee that even if the US is reluctantly launches a long drawn out military campaign it can take out all out Iran's nukes. Moreover nobody can now destroy nuclear knowhow that Tehran had acquired. The world is perhaps now offering the best option away from an attack on Iran's well guarded nuclear facilities, and a chance for Iran to join the global community after 36 years of isolation. This nuclear deal there for perhaps could become Barack Obamas foreign policy legacy but only if America's lawmakers and Iran's enemies in Western Asia allow the agreement to come into force. As for India, the international community releases sanctions and trade embargos on Iran, Indias export to Iran are expected to jump by more than 30% to $6 billion. And Iran's gas reserves, one of the world's largest will be crucial for India's huge energy and power requirements. Most important perhaps is that Iran will offer India inroads into infrastructure including development vital port that will allow access to central Asia and Afghanistan bypassing hostile Pakistan.
