It seems you have little knowledge about Indian Politics. It was during the NDA (read BJP) government; the deal was initiated. Unfortunately, it didn't conclude as NDA was thrown out of power. In the Parliament, PM said to the ex PM that "what you had initated... I have completed". Now the opposition leaders are crying over the spilt milk... had they been in power, they all would have done the same thing what PM has done today...which is right because that is the need of the hour for our Indian economy to meet our growing energy demands.
