I have a problem with the justification you provide for the Jews not approving of the Nuke deal.
I agree that Jews would not like India and Iran getting closer and that they have influence over the senators and the reps.
I also agree that they would like to weaken Iran as much as possible before any war breaks out.
I am not sure how these facts deduce that they should thwart the nuke deal. On the contrary, I think it is in their best interests to make this deal a success. It is know that India faces energy problems. These problems could be solved by the Iranian gas pipeline OR ithey can be solved by having more nuclear power plants and nuclear fuel. Now, if they want to weaken Iran, they should support the deal, let India have the nuclear fuel and thereby solve India\'s energy problems. Having its energy problems solved, India would be more inclined to scrap the pipeline project, harming Iran\'s economy.
