1964～1968年间,在中国核试验成功后,印度国内围绕核政策选择问题展开讨论。1964～1966年,讨论的焦点是印度是否要发展核武器,结论是印度保有发展和平目的核爆炸装置的权利。1964～1967年,印度政府又试探大国向本国提供核保护伞的可能性,但也没有如愿。1967～1968年,印度核政策选择争论的核心转变为是否签署《核不扩散条约》。几经谈判,印度对此条约予以拒绝。 Between 1964 and 1968, following the successful nuclear test in China, India conducted discussions on the issue of nuclear policy options. From 1964 to 1966, the focus of discussion was whether India would develop nuclear weapons, concluding that India retains the right to develop nuclear explosive devices for peaceful purposes. From 1964 to 1967, the Indian government again tried to explore the possibility of a nuclear power umbrella provided by the big powers to their own countries, but they did not do so. From 1967 to 1968, the core issue of India’s nuclear policy debate was whether to sign the Nuclear Non-Proliferation Treaty. After several negotiations, India rejected the treaty.
