On a visit to London on 4 October 1964, anticipating the Chinese test, Bhabha said that India could conduct a nuclear test within a year and a half of a decision to do so, but that he did not "think such a decision will be taken". A 28 October 1964 Indian Express survey found that public opinion leaders across India now took "for granted" Bhabha's claim that India could develop a nuclear bomb within a year and a half. Yet, this figure was likely an overestimate. In 1996, Raja Ramanna, the physicist tasked in 1965 with directing the nuclear weapons project, said: "I don't think it would have been possible to do what Bhabha said—build a device in 18 months. A crash program could have been done, I suppose, but it would have been very expensive." By 1965, Bhabha had updated his estimate from eighteen months to at least five years.
