Which of the following treaty was rejected by India as discriminatory as it prevented only non-nuclear countries from acquiring nuclear weapons?

Non Proliferation Treaty

The correct answer is Option (2) → Non Proliferation Treaty

Another crucial development of the 1970s was the first nuclear explosion undertaken by India in May 1974. Nehru had always put his faith in science and technology for rapidly building a modern India. A significant component of his industrialisation plans was the nuclear programme initiated in the late 1940s under the guidance of Homi J. Bhabha. India wanted to generate atomic energy for peaceful purposes. Nehru was against nuclear weapons. So he pleaded with the superpowers for comprehensive nuclear disarmament. However, the nuclear arsenal kept rising. When Communist China conducted nuclear tests in October 1964, the five nuclear weapon powers, the US, USSR, UK, France and China (Taiwan then represented China)- also the five permanent members of the UN security council- tried to impose the Nuclear Non-proliferation Treaty (NPT) of 1968 on the rest of the world. India always considered the NPT as discriminatory and refused to sign it. When India conducted its first nuclear test, it was termed a peaceful explosion. India argued that it was committed to the policy of using nuclear power only for peaceful purposes.

NUCLEAR NON-PROLIFERATION TREATY (NPT): Allows only the nuclear weapon states to have nuclear weapons and stops others from acquiring them. For the purposes of the NPT, a nuclear weapon state is one which has manufactured and exploded a nuclear weapon or other nuclear explosive device prior to 1 January 1967. So there are five nuclear weapon states: US, USSR (later Russia), Britain, France and China. Signed in Washington, London, and Moscow on 1 July 1968. Entered into force on 5 March 1970. Extended indefinitely in 1995.
