If they cant go with deal and put lames on us then there is no point in going with them. We will work hard and will prove them that they need us, and WE DO NOT NEED THEM.
Our relation with Iran is different thing and with Russia is different. Why should we spoil our relation with any country who is helping us or of some benefit to us just because USA is not getting petrol or gas from that. Come on man we are grown up and smart enough too to understand the tacttics.
But finally ask Indian scientists, do we really need this deal otherwise put it in garbage.
