This does not mean there are no areas of disagreement between the two countries. Of the four issues on which the talks have centred, two still remain contentious-whether India should sign the CTBT; and what kind of nuclear arsenal (weapons and delivery systems) it should aim to establish. For most of the year after Pokhran-II, signing the CTBT was the main obstacle to an accord. The issue was not so much international as domestic for none of the Opposition parties could resist the temptation to destabilise Prime Minister Atal Behari Vajpayees shaky coalition by beating the drum of nationalism. But in the past six months, the CTBT has lost much of its sting. No one has been able to show how India, after having exploded five bombs of various sizes in May 98, would benefit from keeping the option of indulging in more nuclear tests open. Some months ago, Jaswant Singh indicated that the BJP-led National Democratic Alliance had no objection to the CTBT in principle, but that such an important decision could only be taken after a consensus had emerged in the country on the issue. In a host of private statements on the subject, Opposition leaders ranging from I.K. Gujral to Manmohan Singh have made it clear that their objections had more to do with being kept in the dark on such an important issue than to the treaty itself.
