Nuclear deal is todays and tommorow's need to do industrial and agriculture growth.Its person's right to oppose or agree with deal but in huge interst of nation they should not give threat to govt breakdown.Its simply blackmailing to get hidden benefits from congress.Pakistan is fighting to get nuclear energy deal,china is hiddenly opposing deal so that india can't grow faster.If bureaucracy made and renegotiate deal,they are aware about its benefits and drawbacks,i think they think more positive about nation than left.Everbody can't judge deep benefits of deal without considering its technical,economic benefits.
