This nuclear deal will nuke the CPM out of the national scene. They have had power without accountability for way too long. If CPM is seen as siding with the BJP on this issue, they would lose their vote bank. If they go ahead and let the govt sign the deal with the US, then again they would lose face. As such, Advani asked them to prove their mettle to follow up their bark with a bite. Either way, Congress would stabilize as will BJP. Commies who have always barked will have time to tend to their throats once the new election schedule is announced. BJP was able to rule the country for 6 years. But Congress could not. That way, it will be BJP vs congress at the hustings. It will definitely be 2 major parties in the country next election time.
