BJP government was the architect of this idea but they could not take it to conclusion as their term ended. Congress only followed BJP and expanded on that. If Dr. Singh was such a great person, why is he going back now? If you think this is just a game, dream on. Time is everything. If this deal is delayed beyond this year, you conclude it is dead. America will not have time to approve this deal next year as they will be in election mode. Congress will do anything to save their power including destroying/sacrificing the country's interests.
