India's constitution does not require treaties signed by govt to get Parl aprroval to become law, so as it stands, the treaty signed by the PM MMS, is already legally binding. And everyone knows that the left is not bothered about India's growth, especially if ti can pose a threat t the dominance of their masters in beijing. This whole brouhaha is just bollocks - one huge farce by Beijing's agent provocatuers, the Commies, led by CPI to derail the N-deal, by their daily mouthing all manner of threats and terrible consequences if the deal is 'operationalized', yet they have openly and categorically ruled out putting the treaty to a vote or pulling their outside support and thus bringing down the UPA govt. So the heck with the Commie traitors - MMS for once showed some balls in challenging these Commie traitors go through with thier threats, and he won hands down - the Commies know that without the coat-tails of UPA, they'll be nowhere - no seat at the table of power, so they'll continue with thier empty threats, in order to keep the attention of their stupid, brainless, ignorumas followers.
