I doubt Congress will take BJP's support and go ahead with the deal. Please note this deal does not require a Parliamentary approval. So only the fear of elections is putting the deal in back burner. But BJP should come forward and make it clear that they support the deal and the government should go ahead. Still they can request a domestic law to override Hyde Act of USA. We should not miss this opportunity for several reasons.
1. There is more than power generation issue here. This is strategic as the deal will put us in the same league of nuclear nations.
2. In his quest to achieve some success in foreign policy, Bush is being generous to India regarding this deal and the next administration will not be that generous.
3. This deal is limited to India and Pakistan is crying foul. The next administration might club both the nations together and as a result we will not get anything substantial.
4. If Democrats come to power in USA after next elections, they will rather cozy up with China rather than India.
Also, Congress should bear full responsibility for any failure to operationalize the deal as they are in power now. If they think they can get full credit for the deal and blame their ally Communists for the failure, they will be in for a rude shock. They will be held responsible. They should put nation above their lust for power and go ahead with this deal.
