Contradicting the BJP's views on the nuclear deal with the U.S., the former National Security Adviser, Brajesh Mishra, has said India should go ahead with the agreement, failing which the country would suffer a "severe loss of face' and its atomic programme a setback. Mr. Mishra, who served in the previous BJP-led government, said the deal should be concluded during the tenure of Bush administration as change of government in the U.S. would make things difficult. Noting that he had talks with government representatives and scientists, Mr. Mishra said he was convinced that the deal would not affect India's strategic programme.
