However, much water has flown under the bridge since May 11, when the principal secretary to the prime minister, Brajesh Mishra, announced that India was prepared to adhere to some provisions of the CTBT. "This cannot be done in a vacuum. It would necessarily be an evolutionary process from concept to commitment and would depend on a number of reciprocal activities," he said. But under pressure from the world powers, particularly with the US and the European Union demanding that India sign the CTBT unconditionally, the Indian response since then has been, to put it mildly, confused. On May 27, Prime Minister Atal Behari Vajpayee, while reiterating that India would observe a voluntary moratorium and refrain from conducting underground nuclear tests, told Parliament that India was willing to move "towards a de jure formalisation of this declaration"—in other words, that India was willing to sign the CTBT.
