Nuclear Non-proliferation Treaty (NPT)

The Nuclear Non-Proliferation Treaty (NPT) is a landmark international accord designed to prevent the spread of nuclear weapons and promote the peaceful use of nuclear energy. Emerging in the geopolitical aftermath of the Second World War, the treaty represents one of the most significant achievements of multilateral diplomacy in the domain of global disarmament and arms control. Since its entry into force in 1970, it has served as the cornerstone of the international non-proliferation regime and has contributed to limiting the number of nuclear-armed states.

Background and Historical Development

After the devastation caused by the atomic bombings in 1945, the international community became acutely aware of the destructive potential of nuclear weapons. At that time, only the United States possessed a nuclear arsenal. In 1946, the Baruch Plan was introduced in the United States, proposing the establishment of an international atomic development authority that would control all nuclear materials and ensure their peaceful use. The plan also recommended a system of automatic sanctions that could not be vetoed by the United Nations Security Council. However, the proposal failed to gain approval due to opposition from the Soviet Union, which intended to veto it in the Security Council.
A significant advancement came under President Dwight D. Eisenhower’s “Atoms for Peace” initiative, which laid the foundation for the creation of the International Atomic Energy Agency (IAEA) in 1957. The IAEA was mandated to promote peaceful nuclear cooperation while ensuring that such activities did not contribute to weapons development.
By the early 1960s, four countries—the United States, Soviet Union, United Kingdom, and France—had developed nuclear weapons, while China joined this group later. The increasing number of nuclear-capable states raised global concerns about proliferation risks. Consequently, negotiations commenced at the Eighteen Nation Disarmament Committee (ENDC), leading to the drafting of the Nuclear Non-Proliferation Treaty in 1968. The United Nations General Assembly endorsed the text in June 1968, and the treaty opened for signature in Washington, London, and Moscow the following month. It officially entered into force on 5 March 1970.

Objectives and Core Principles

The NPT rests upon three interlinked objectives, often referred to as its three pillars:

1. Non-Proliferation – To prevent the spread of nuclear weapons and associated technology to states that do not already possess them.
2. Disarmament – To promote the gradual reduction and eventual elimination of existing nuclear arsenals.
3. Peaceful Use of Nuclear Energy – To enable cooperation among states for the peaceful development of nuclear science and technology under appropriate safeguards.

These objectives embody a delicate balance between the rights and obligations of nuclear-weapon and non-nuclear-weapon states.

Membership and Implementation

The NPT came into effect in 1970 and was extended indefinitely in 1995. It has 190 state parties, making it one of the most widely adhered-to arms control agreements in history. All five permanent members of the United Nations Security Council (P5)—the United States, Russia (formerly the USSR), the United Kingdom, France, and China—are signatories. However, India, Pakistan, and Israel have never acceded to the treaty, citing concerns over its discriminatory structure. North Korea joined in 1985 but announced its withdrawal in 2003 following international disputes over its nuclear programme.

Key Provisions and Summary of Articles

The treaty consists of a Preamble and Eleven Articles, summarised as follows:

• Article I: Nuclear-weapon states shall not transfer nuclear weapons or technology to any recipient, directly or indirectly.
• Article II: Non-nuclear-weapon states agree not to receive or manufacture nuclear weapons or seek assistance in doing so.
• Article III: Non-nuclear-weapon states must accept IAEA safeguards to verify compliance with treaty obligations.
• Article IV: Recognises the right of all parties to access nuclear energy for peaceful purposes without discrimination, and to participate in technological exchange.
• Article V: Ensures that the potential benefits of peaceful nuclear explosions are shared equitably with non-nuclear states.
• Article VI: Commits all parties to pursue negotiations on disarmament and the cessation of the nuclear arms race.
• Article VII: Allows regional treaties to establish nuclear-weapon-free zones.
• Article VIII: Details procedures for proposing and adopting amendments to the treaty.
• Article IX: Specifies that the treaty is open for signature and outlines procedures for ratification and accession.
• Article X: Grants any party the right to withdraw from the treaty if extraordinary events jeopardise its national interests.
• Article XI: Declares all official texts of the treaty authentic and lists the depositary governments—the United States, United Kingdom, and the former USSR.

The Review Conferences, held every five years, assess the implementation of the treaty and reaffirm commitments to its objectives.

Challenges and Criticism

Despite its success in limiting proliferation, the NPT faces several enduring challenges:

• Discriminatory Framework: The treaty legally recognises only five nuclear-weapon states—those that tested nuclear weapons before 1 January 1967—creating a permanent division between “nuclear haves” and “nuclear have-nots.”
• Slow Disarmament Progress: Nuclear-weapon states retain vast arsenals and have been reluctant to pursue complete disarmament, contrary to the spirit of Article VI.
• Enrichment and Reprocessing Risks: The technology used for peaceful nuclear energy can be diverted for weapons development, representing what analysts call the “Achilles’ heel” of the regime.
• Withdrawal and Non-Compliance: North Korea’s withdrawal and subsequent nuclear tests highlight limitations in enforcement mechanisms.

To address these gaps, the NPT is supplemented by frameworks such as the Nuclear Suppliers Group (NSG), which regulates exports of sensitive nuclear materials and technology to prevent proliferation.

India’s Position and Engagement with the NPT

India has consistently maintained that it will not sign the NPT, describing it as an inherently discriminatory treaty. Successive Indian governments, regardless of political affiliation, have upheld this position. India argues that the treaty creates an unjust division by conferring nuclear legitimacy on a select group of states while permanently denying others similar rights.
Key aspects of India’s stance include:

• The NPT lacks an equitable basis as it restricts legal possession of nuclear weapons to those tested before 1967, without moral or logical justification.
• The nuclear-weapon states have not demonstrated genuine commitment to disarmament, retaining significant stockpiles of warheads.
• India adheres to a “No First Use” policy, pledging not to employ nuclear weapons unless attacked first by an adversary using them.
• Since 1998, India has maintained a voluntary moratorium on nuclear testing, reflecting its commitment to responsible behaviour.
• India emphasises the need for universal and non-discriminatory verification mechanisms, arguing that genuine non-proliferation must apply equally to all states.

Although India remains outside the NPT framework, it has engaged constructively with the international community on non-proliferation issues, including through its civil nuclear cooperation agreement with the United States (2008) and participation in nuclear export control regimes.
