I don't think we should interfere in their affairs, India is not hurting us anyway. Besides, we don't need any more enemies.

@Bad Guy regardless of what I said, it's easy for you to show enthusiasm, but unfortunately it is not your decision to make. You should wait and see how much pressure the US and Israel will put on India against ANY cooperation with Iran on ANY level. They want so badly to isolate Iran and they will stop at nothing to achieve this. Indian leadership needs to be strong to resist such pressure.
