If the present government is so keen to go ahead with the deal, why not they speak to the BJP being the main opposition party. Call all party meeting, sort out the difference if any and ensure that the deal is putforth unanimously.
A Government who wish to take any decision in the interest of the nation should remove the doubts of its people even if such doubts are from their enemies.
Just for the sake of running away from the worst situation like rising of prices of essential commodities, oil, inflation etc. the MMS Government want to divert the minds of common public and they found a golden chance by way of nuke deal which they utilize cleverly. The only difference between congress and other parties is that congress know how to cover up their mistakes.
