But many analysts feel that India should cash in on the leverage it has gained by going nuclear. Says strategic analyst Brahma Chellaney: "Unless India is co-opted into the nuclear non-proliferation regime, this regime will crumble. We have a few trump cards which we need to use to the fullest extent possible." What about the negotiations between India and the US, the second round of which ended in Frankfurt on Thursday between Vajpayee's special emissary Jaswant Singh and US deputy secretary of state Strobe Talbott, apparently without achieving anything? Chellaney asserts that at present India is only "beating the traditional nuclear powers by saying it is willing to sign the treaty on the basis of reciprocal actions. It does not mean that we will sign it. We are trying to find out what concessions are possible." He doesn't view this as a reversal of India's stand on the CTBT: "They are playing a game, we are also playing a game. In fact, the Clinton visit is being used to apply pressure on us, to force us to put our cards on the table. We should forget the visit for the time being." The next round is scheduled for July 20 and 21 in New Delhi.
