 Indian nuclear policy was set by unwritten personal understanding between Nehru and Bhabha.Nehru famously said to Bhabha, "Professor Bhabha take care of Physics, leave international relation to me".From the outset in 1948, Nehru had high ambition to develop this program to stand against the industrialised states, and to establish a nuclear weapons capability as part of India's regional superiority to other South-Asian states, most particularly Pakistan.
