Iis not a matter of choice that is chosing US or Iran. The question here is whether we are going to let US DICTATE to India what we should do and with whom we should maintain relationship.
Please do not divert the attention from debate.
Neither Iran nor US has ever helped India. No country inthis world helps others for charity. All nations have their own interests in what ever they do. This is the reason we often head "Supreme National Interest".
US and Iran are playing a game and WE MUST NOT BECOME A JOKER IN THEIR GAME. Let them fight and solve their problem on their own. We will neither help US or IRAN.
We need GAS from Iran (US does not want this to happen because this will mean that Indians will have alternative to Nuclear deal and IRANIANS will make money) and we need commerce with US. So we will remain out of their problem.
Our stand should be that IRAN must disclose the details of their Nuclear program (because they signed on NPT) and US must give assurances for not resorting to military options as they have done in Iraq case.
We support the peaceful use of nuclear technology and after Iran declares the information about its nuclear programme the culprits (including AQ Khan and company) must be prosecuted in international courts.
