GS 2: Effect of Policies and Politics of Developed and Developing Countries on India’s interests

Context: The renewed tensions between Iran and the United States, coupled with disagreements over Iran’s uranium enrichment programme, have once again brought the issue of nuclear non-proliferation to the forefront. The ongoing negotiations reflect the broader challenge of balancing global security, state sovereignty, and the effectiveness of the international non-proliferation regime.

What is Nuclear Non-Proliferation?

Nuclear Non-Proliferation refers to global efforts aimed at preventing the spread of nuclear weapons, promoting the peaceful use of nuclear energy, and achieving progressive nuclear disarmament.
It is primarily governed by the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), which seeks to reduce the risk of nuclear conflict while facilitating peaceful nuclear cooperation.

Nuclear Non-Proliferation Treaty (NPT), 1968

Objectives of the NPT

The treaty aims to prevent the spread of nuclear weapons to additional countries.
It promotes the peaceful use of nuclear energy under international safeguards.
It commits nuclear-weapon states to pursue nuclear disarmament through future negotiations.

Key Features

The treaty recognises only five Nuclear Weapon States (NWS)—United States, Russia, United Kingdom, France, and China—as countries that possessed nuclear weapons before 1 January 1967.
Non-nuclear weapon states agree not to acquire nuclear weapons and accept safeguards administered by the International Atomic Energy Agency (IAEA).
In return, they receive access to peaceful nuclear technology for civilian purposes under international supervision.

India’s Position on the NPT

Why Has India Not Signed the NPT?

India considers the treaty discriminatory because it permanently divides countries into nuclear “haves” and “have-nots.”
The treaty does not impose a time-bound obligation on nuclear weapon states to eliminate their arsenals.
India believes that global disarmament should be universal, non-discriminatory, and verifiable.

India’s Responsible Nuclear Record

Despite remaining outside the NPT, India has maintained a credible minimum deterrence policy.
India follows a No First Use (NFU) doctrine and maintains strict export controls on nuclear materials.
India received a Nuclear Suppliers Group (NSG) waiver in 2008, enabling international civil nuclear cooperation despite being a non-signatory.

Iran Nuclear Issue

Iran’s Stand

Iran argues that uranium enrichment for peaceful purposes is its sovereign right under the NPT.
It maintains that its nuclear programme is intended for civilian energy and scientific purposes rather than nuclear weapons development.

Concerns of Western Countries

The United States and several Western nations believe that high levels of uranium enrichment could enable Iran to develop nuclear weapons capability.
They seek restrictions on Iran’s enrichment programme through international agreements and inspections.

Joint Comprehensive Plan of Action (JCPOA), 2015

Major Provisions

Iran agreed to limit uranium enrichment to 3.67%, reduce its stockpile of enriched uranium, and permit extensive IAEA inspections.
In return, international economic sanctions imposed on Iran were significantly eased.

Collapse of the Agreement

In 2018, the United States withdrew from the JCPOA and re-imposed sanctions on Iran.
In response, Iran gradually increased its uranium enrichment levels to around 60%, raising international concerns over potential weaponisation.

Challenges in the Global Non-Proliferation Regime

Perceived Double Standards

The NPT allows five recognised nuclear powers to retain nuclear weapons while restricting others, creating concerns over inequity and discrimination.
Many countries question whether the treaty has been implemented uniformly across all states.

Lack of Progress on Nuclear Disarmament

Although nuclear weapon states committed to pursue disarmament, global nuclear arsenals continue to exist.
This weakens the credibility of the international non-proliferation framework.

Trust Deficit

The withdrawal of the United States from the JCPOA reduced confidence in long-term international agreements.
Frequent policy changes create uncertainty regarding future diplomatic commitments.

Security Dilemma

States often pursue nuclear capabilities because they perceive them as essential for deterrence against external threats.
This creates a cycle where one country’s pursuit of security increases insecurity for others.

Important Concepts for Mains

Nuclear Deterrence

Nuclear deterrence refers to preventing aggression by maintaining the capability to inflict unacceptable damage on an adversary.
Several countries view nuclear weapons as a means of ensuring their national security against external threats.

Russell–Einstein Manifesto (1955)

The Russell–Einstein Manifesto warned that humanity must choose between nuclear disarmament and the risk of global destruction.
It highlighted the existential threat posed by nuclear weapons and called for peaceful international cooperation.

Way Forward

Strengthen the NPT Framework

The international community should work towards making the non-proliferation regime more equitable, transparent, and universally accepted.

Pursue Time-Bound Nuclear Disarmament

Nuclear weapon states should demonstrate genuine commitment to Article VI of the NPT by adopting a credible roadmap for gradual disarmament.

Revive Diplomatic Engagement

Dialogue and negotiated agreements such as the JCPOA should be revived to address proliferation concerns while respecting legitimate peaceful nuclear rights.

Strengthen the Role of the IAEA

The IAEA should continue to conduct independent, credible, and transparent inspections to build international confidence.

Promote Universal Nuclear Security

Countries should cooperate to strengthen nuclear safety, export controls, non-proliferation norms, and confidence-building measures to reduce global nuclear risks.

Conclusion

The challenge of nuclear non-proliferation lies in balancing national security, state sovereignty, and global peace. While preventing the spread of nuclear weapons remains essential, lasting stability requires non-discriminatory international rules, credible disarmament efforts, and sustained diplomatic engagement. An equitable and rules-based global nuclear order remains indispensable for long-term international security.
