My point is that the next Govt, whether Congress or BJP, with a simple majority could still go ahead with the deal, (because, as admitted by Karat himself, BJP is opposing the deal only to push for early elections). So Left is continuing with this hardline approach to keep its cadres happy and nothing good is going to come out of their folly. As for the deal, its an agreement, where both parties will be interested to gain from it. Why should we expect US to be philanthropic? The deal in its present shape leaves scope for India to pull out of it anytime and the situation would not be worse than what is now. On the other hand, right after Pokhran blast in 1974, the aim of India was to secure nuclear cooperation, without signing the NPT, which has been achieved by the present deal (The only country, which is not a NPT-signatory, being given such a deal by US or other counties)
