After the UPA government winning the trust vote, the focus has once again shifted to the United States, which hopes that the Indo-US nuclear deal will soon become a reality.

US officials and lawmakers on Capitol Hill close to the Indo-US nuclear agreement were watching intently as the trust vote unfolded in Indian Parliament on Tuesday. As the Prime Minister (PM) emerged victorious, there was immediate reaction in Washington where's there's fresh optimism now that the agreement is back on track.

Experts say now India must act quickly to make sure it can deliver the agreement back to the US congress for a final mandatory approval before the Congressional calendar expires in September. The agreement enjoys support among Republicans and Democrats on Capitol Hill. And lawmakers are expected to give a thumbs-up to the deal if India were to send it back in time.

Joe Wilson, Congressman, Washington DC, said “We all know that India could be one of the most significant countries in the world but its got to have an energy source that can be counted upon and that's the good news about nuclear power. Its very reliable power its very clean and it will be very beneficial to the people of India.

Experts also agree the agreement will sail through the Nuclear Suppliers Group (NSG) with member countries including UK, Australia and Russia backing the agreement.

Stephen Cohen, South Asia Expert, said “It will go through very quickly through NSG. Because I know the American diplomats have been working on this issue, the Indians are pushing it and I have heard that other countries that are regarded as problems are going to support it."
