BJP are as big traitors as the Commies(CPI/M). By voting against the deal they are directly helping China's gameplan.
Everytime it gives some stupid reasons as to why they are not supporting the deal, but the fact of the matter is that they are not ready to give Congress credit for this historic accomplishment.
It was time to rise above petty politics and think what was good for the country. But by opposing the deal, BJP proved that they are also traitors like the CPI/M.
