Nuclear Non-Proliferation Treaty

Also called: NPT · Topic: India's External Relations, 1947-1999: Non-alignment, Wars and Nuclear Policy · NCERT: Class 12, Ch 4 "India's External Relations"

Meaning

The Nuclear Non-Proliferation Treaty (NPT) is a treaty, opened for signature in 1968. It lets only five states keep nuclear weapons: those that "manufactured and exploded" a nuclear device before 1 January 1967. Every other state that signs it must promise never to build such weapons [8].

It matters because India saw the NPT as discriminatory and has never signed it. This refusal shaped India's nuclear policy from 1968 to the 1998 tests and beyond.

Explanation

How the treaty works

• Opened for signature: 1 July 1968. Came into force: 5 March 1970 [7].
• Two classes of states:
• Nuclear-weapon states: under Article IX(3), a nuclear-weapon State is one that "has manufactured and exploded a nuclear weapon or other nuclear explosive device prior to 1 January 1967" [8].

• Non-nuclear-weapon states: every other state that signs. Each one promises never to build nuclear weapons.

• The five nuclear-weapon states are the US, USSR, UK, France and China.

• They were also the five permanent members of the UN Security Council.

• Taiwan held China's UN seat at that time.

• The cut-off date matters. It is fixed in the past. No state that tests later can join the "allowed" club.

Why India rejected it

• Discriminatory: it makes two classes of states, those allowed to have the bomb and those not allowed.
• No deadline for the five: it does not make the five give up their own weapons within any fixed time.
• Clash with Nehru's vision:
• Nehru wanted comprehensive disarmament, meaning all countries give up all their nuclear weapons.

• The NPT froze inequality and did not deliver that.

• Security worry: China tested a bomb in October 1964, two years after defeating India in the 1962 war. The NPT would have allowed China to keep the bomb while banning it for India.

• Result: India has never signed the NPT.

Review and the 1995 indefinite extension

• Article X(2) said a conference would be held 25 years after the treaty came into force. It would decide whether the treaty should continue indefinitely [8].
• 1995: the treaty was extended indefinitely, meaning it has no end date.
• India opposed this because it made the monopoly of the five permanent. A monopoly here means only those five can legally have the bomb.

In the Constitution and practice

• Constitutional base:
• Foreign affairs and treaties are Union subjects (Union List, Seventh Schedule). So the Union government decides whether India signs a treaty such as the NPT.

• Article 51 (a Directive Principle, a guideline for the state that courts cannot enforce) asks the state to promote international peace and security. India used this kind of language when it argued for global disarmament instead of an unequal treaty.

• How India's stand worked in practice:

• 1948: the Atomic Energy Commission was set up. 1954: the Department of Atomic Energy was set up. Both were under Homi J. Bhabha, and their stated aim was peaceful use of atomic energy.
• 1968: India refused to sign the NPT.
• 18 May 1974, Pokhran-I ('Smiling Buddha'): India tested a device outside the NPT and called it a "peaceful nuclear explosion", meaning a blast for peaceful uses such as engineering, not for a weapon.
  • Because India was outside the NPT, the world's answer was the Nuclear Suppliers Group (NSG, 1974-75) and stricter controls on supplies to India.
• 1995: India opposed the NPT's indefinite extension.
• 1996: India refused to sign the CTBT for the same reason: it protected the monopoly of the five.
• 11 and 13 May 1998, Pokhran-II ('Operation Shakti'): five tests that showed India could make nuclear weapons. Pakistan tested on 28 and 30 May 1998.
  • UNSC Resolution 1172 (6 June 1998) was adopted unanimously and condemned both countries' tests [5][6].

• 2008: the NSG gave India a waiver (a special exemption from its rules), even though India is outside the NPT. India is still not a member of the NSG.

• Lasting effect:

• India stays outside the NPT as a state that has nuclear weapons.
• It explains its restraint through its own doctrine instead: credible minimum deterrence, no first use and civilian control through the Nuclear Command Authority [2][3].

Don't confuse with

• CTBT (1996): bans all nuclear test explosions, for any purpose. The NPT bans owning weapons for all states except the five. The CTBT is not yet in force because all 44 Annex 2 states, including India, have not ratified it [4]. The NPT has been in force since 1970 [7].
• NSG (1974-75): a group of supplier countries that controls nuclear exports. It is not a treaty states sign. It was formed after Pokhran-I, not after the NPT.
• Nuclear-weapon state (NPT sense) vs a state that has nuclear weapons: in NPT law the term covers only those that tested before 1 January 1967 [8]. India and Pakistan tested later, so they can never be "nuclear-weapon States" under the NPT.
• Indefinite extension (1995) vs signing (1968): India did not "withdraw" from the NPT. It never signed. In 1995 it only opposed the extension.

Prelims Hooks

• NPT dates: opened for signature on 1 July 1968, came into force on 5 March 1970 [7].
• Article IX(3): a nuclear-weapon State is one that exploded a nuclear device before 1 January 1967 [8]. Trap: the cut-off is 1967, not 1968, the year the treaty opened.
• The five recognised nuclear-weapon states: US, USSR (now Russia), UK, France, China. These are the same as the five permanent members of the UNSC.
• Article X(2) provided for a conference 25 years after entry into force. This led to the indefinite extension in 1995, which India opposed [8].
• Trap: India has never signed the NPT or the CTBT, yet it got an NSG waiver in 2008. It is not an NSG member.
• Trap: the NSG was formed after Pokhran-I (1974), not after the NPT (1968).

Mains Points

• An unequal nuclear order vs strategic autonomy:
• The NPT splits the world into states that may keep the bomb and states that may not. It has no deadline for the five to disarm.
• India refused to sign but kept asking for global, verifiable and non-discriminatory disarmament.

• This was the nuclear side of non-alignment: India kept its freedom to make its own choices (strategic autonomy).

• Did staying outside the NPT pay off?

• Costs:
  • The NSG controls came after 1974.
  • Sanctions and UNSC Resolution 1172 came after 1998 [5].
  • Pakistan matched India's tests within weeks.

• Gains:

  • India got deterrence against China.
  • Its record of restraint (no first use, voluntary moratorium on testing, civilian control) helped win the 2008 NSG waiver without signing the NPT.

• Reform debate:

• India argues that a fair nuclear order must bind the five as well, with a fixed timeline for disarmament.
• Critics reply that staying outside the NPT keeps India out of full NSG membership.
• So the question for a GS-II answer is whether India should keep pushing for a fairer system or adjust to the system as it is.
