Nuclear Non-Proliferation Treaty (NPT): History, Pillars, Failures, and Its Urgent Relevance-2026

The Most Consequential Treaty the World Is Failing to Keep

Imagine a treaty signed by nearly every nation on earth — 191 states — that carries within it a solemn promise: that nuclear weapons will one day be eliminated from the face of the planet. Now imagine that, more than half a century after that treaty entered into force, global nuclear arsenals still number approximately 12,500 warheads, great powers are modernising their weapons at unprecedented cost, new nuclear rivalries are emerging, and the treaty’s cornerstone review process is collapsing in disagreement.

That is the paradox of the Nuclear Non-Proliferation Treaty (NPT) — the most ambitious arms control instrument in human history, and one of its most embattled.

The NPT is not merely a security document. It is, at its foundation, a human rights instrument. Nuclear weapons are uniquely indiscriminate in their capacity for destruction — they cannot, by their very nature, distinguish between civilians and combatants. Their use would constitute the gravest possible violation of the right to life, the right to health, and the right to a healthy environment. Every nuclear warhead that exists is a standing threat to human dignity itself.

In this comprehensive analysis, we examine the Nuclear Non-Proliferation Treaty: where it came from, what it promises, how it has been implemented, where it has been broken, and why its relevance — far from fading — is more urgent in 2025 than at any time since the height of the Cold War.

Historical Background: How the NPT Came to Be

The Atomic Age and Its Horrifying Birth

The nuclear age began on 6 August 1945, when the United States dropped an atomic bomb on Hiroshima, Japan, killing an estimated 80,000 people instantly and ultimately causing the deaths of 140,000 by the end of 1945. Three days later, a second bomb fell on Nagasaki, killing 40,000 immediately and 80,000 by year’s end. These acts of mass destruction — which remain the only wartime uses of nuclear weapons in human history — inaugurated an era in which humanity possessed, for the first time, the capacity for its own total annihilation.

The Soviet Union conducted its first nuclear test in 1949, breaking the American monopoly. The United Kingdom followed in 1952, France in 1960, and China in 1964. By the early 1960s, the world had lived through the Cuban Missile Crisis of 1962 — thirteen terrifying days in which the United States and Soviet Union came closer to nuclear war than at any other moment in history — and the international community understood with visceral clarity that unchecked nuclear proliferation was an existential threat.

Negotiations and the Birth of the NPT

The Partial Test Ban Treaty (PTBT) of 1963 — which prohibited nuclear tests in the atmosphere, underwater, and in outer space — was an important first step. But it was not enough. Growing alarm at the spread of nuclear technology and the prospect of dozens of nuclear-armed states drove intense diplomatic activity throughout the mid-1960s.

The Nuclear Non-Proliferation Treaty was opened for signature on 1 July 1968 and entered into force on 5 March 1970. It was the product of years of negotiation, primarily between the United States and Soviet Union — fierce adversaries who nonetheless recognised a shared interest in preventing nuclear weapons from spreading further. The treaty was notable for bringing together nuclear-armed and non-nuclear states in a single binding agreement, creating a framework of mutual obligation.

The NPT was originally designed with a 25-year term, subject to extension. In 1995, the treaty was extended indefinitely by consensus — a landmark achievement that reflected the international community’s commitment to maintaining the NPT framework even as debate over its implementation intensified.

The Three Pillars of the NPT: A Grand Bargain

The architecture of the Nuclear Non-Proliferation Treaty rests on three interconnected pillars. Together, they represent what is often called the “grand bargain” — an exchange of commitments between nuclear-weapon states (NWS) and non-nuclear-weapon states (NNWS).

Pillar One: Non-Proliferation

Under Article II of the NPT, non-nuclear-weapon states commit never to acquire or develop nuclear weapons. Under Article I, the five recognised nuclear-weapon states — the United States, Russia, the United Kingdom, France, and China (the P5, who are also the five permanent members of the UN Security Council) — commit never to transfer nuclear weapons or nuclear weapons technology to non-nuclear states.

This pillar has been largely, though not universally, successful. The NPT created a near-universal norm against nuclear weapons acquisition. Of the states that have considered or pursued nuclear weapons programmes, many — including South Africa, Libya, Ukraine, Kazakhstan, and Belarus — ultimately abandoned or gave up their nuclear weapons, often citing NPT commitments as part of their rationale.

Pillar Two: Disarmament

Article VI is the heart of the NPT’s promise to non-nuclear states. It reads:

“Each of the Parties to the Treaty undertakes to pursue negotiations in good faith on effective measures relating to cessation of the nuclear arms race at an early date and to nuclear disarmament, and on a Treaty on general and complete disarmament under strict and effective international control.”

This is the pillar that nuclear-weapon states have most egregiously and consistently violated. The P5 committed to pursuing nuclear disarmament — not as a distant ideal but as a binding legal obligation. Fifty-five years after the NPT entered into force, they remain nuclear-armed, they are modernising their arsenals, and they have made no credible progress toward the “general and complete disarmament” Article VI requires.

The failure of the disarmament pillar is not a technicality — it is the fundamental breach that has corroded the NPT’s legitimacy and fuelled non-nuclear states’ growing frustration with the treaty’s implementation.

Pillar Three: Peaceful Uses of Nuclear Energy

Article IV recognises the “inalienable right” of all parties to develop nuclear energy for peaceful purposes, including research, production, and use of nuclear energy. The NPT thus facilitates access to civilian nuclear technology — under IAEA safeguards — as a benefit of treaty membership.

This pillar creates genuine tension with the non-proliferation objective: the technologies used to enrich uranium for civilian nuclear power can, with further enrichment, produce weapons-grade material. Iran’s nuclear programme has played out precisely within this tension — insisting on its Article IV rights while the international community concerns itself with the weapons potential of its enrichment capacity.

The Role of the IAEA: Safeguards and Verification

The International Atomic Energy Agency (IAEA), established in 1957, serves as the treaty’s verification arm. Under Article III of the NPT, non-nuclear states must conclude Comprehensive Safeguards Agreements (CSAs) with the IAEA, allowing the agency to inspect nuclear facilities and verify that nuclear material is not being diverted to weapons use.

The discovery of Iraq’s clandestine nuclear weapons programme following the Gulf War (1991) — which had proceeded undetected under IAEA safeguards — exposed serious weaknesses in the original safeguards system. In response, the IAEA developed the Additional Protocol (1997), which gives inspectors significantly broader rights of access, including to undeclared sites and activities. As of 2025, over 140 states have Additional Protocols in force.

The IAEA remains the NPT’s indispensable guardian. Its ability to provide credible verification is what gives the treaty operational meaning — without it, states cannot know whether their neighbours are complying, and the entire framework of mutual trust begins to unravel.

Key Successes of the Nuclear Non-Proliferation Treaty

The Near-Universal Norm Against Nuclear Weapons

The NPT’s greatest achievement is one that is easy to take for granted: today, only nine states possess nuclear weapons, and only four states remain outside the treaty — India, Pakistan, Israel (which maintains a policy of nuclear ambiguity), and North Korea (which announced its withdrawal in 2003). In the early 1960s, projections suggested that as many as 25 to 30 states might acquire nuclear weapons by the 1980s. The NPT dramatically narrowed that trajectory.

States that had nuclear weapons programmes and abandoned them under the NPT framework include:

South Africa: Developed six nuclear weapons under apartheid, voluntarily dismantled them, and joined the NPT in 1991 — the only country in history to have independently developed and then eliminated its nuclear arsenal.
Ukraine, Kazakhstan, Belarus: Inherited large Soviet nuclear arsenals after the USSR’s collapse in 1991. All three acceded to the NPT as non-nuclear states under the Budapest Memorandum (1994), transferring weapons to Russia in exchange for security assurances. (The subsequent violation of Ukraine’s territorial integrity by Russia has become a painful cautionary tale about the value of such assurances.)
Libya: Agreed to dismantle its nascent weapons programme in 2003 following negotiations with the US and UK.

Regional Nuclear-Weapon-Free Zones

The NPT has facilitated the establishment of regional Nuclear-Weapon-Free Zones (NWFZs), creating treaty-based prohibitions on nuclear weapons across large geographic areas. These include:

The Treaty of Tlatelolco (Latin America and the Caribbean, 1967) — the first NWFZ in a populated region
The Treaty of Rarotonga (South Pacific, 1985)
The Treaty of Bangkok (Southeast Asia, 1995)
The Treaty of Pelindaba (Africa, 1996)
The Treaty of Semipalatinsk (Central Asia, 2006)

These zones represent regions where the NPT’s non-proliferation norm has been concretised into binding regional agreements — genuine achievements of arms control diplomacy.

Arms Reduction Agreements Between the Superpowers

During the Cold War and its immediate aftermath, the NPT framework provided the normative context within which bilateral US-Soviet/Russian arms reduction agreements were negotiated:

SALT I and II (1972 and 1979)
INF Treaty (1987) — eliminating an entire class of intermediate-range nuclear weapons
START I and II and New START (1991, 1993, 2010)

At the Cold War’s peak, the US and USSR together possessed over 60,000 nuclear warheads. Through successive arms control agreements, that number fell to approximately 5,550 (US) and 6,255 (Russia) operational and stockpiled warheads combined as of recent estimates — a reduction of over 80%. This is a genuine, if incomplete, achievement.

Critical Failures and Challenges

The Disarmament Deficit: Article VI’s Broken Promise

The most fundamental failure of the NPT is the near-total inability of the nuclear-weapon states to fulfil their Article VI disarmament obligations. Five decades of review conferences have produced repeated demands from non-nuclear states for concrete timelines, interim measures, and verification frameworks toward disarmament — and repeated deflection by the P5.

The 2010 NPT Review Conference produced an Action Plan with 64 steps toward disarmament — but implementation has been minimal. The 2015 and 2022 Review Conferences both failed to adopt consensus final documents, reflecting the depth of the impasse between nuclear and non-nuclear states.

Meanwhile, all nuclear-weapon states are engaged in expensive, long-term programmes to modernise their nuclear arsenals — extending the operational life of existing weapons, developing new delivery systems, and in some cases creating qualitatively new capabilities. The United States, for example, has committed to a nuclear modernisation programme estimated to cost over $1.7 trillion over 30 years. Russia is developing new classes of nuclear delivery vehicles. China is dramatically expanding the size of its nuclear arsenal. These are not the actions of states committed to nuclear disarmament.

North Korea: The NPT’s Most Visible Failure

North Korea’s nuclear programme represents the NPT’s most dramatic failure. Pyongyang acceded to the NPT in 1985, signed an IAEA safeguards agreement, and then — after the IAEA discovered discrepancies in its nuclear declarations — announced its withdrawal from the NPT in January 2003, under a provision (Article X) that allows withdrawal with 90 days’ notice if a state determines that “extraordinary events” have jeopardised its supreme national interests.

North Korea has since conducted six nuclear tests (2006, 2009, 2013, 2016, 2017) and is estimated to possess between 40 and 50 nuclear warheads as of 2025, with the capacity to deliver them on ballistic missiles capable of reaching the continental United States. It has not rejoined the NPT, diplomatic negotiations have repeatedly broken down, and international sanctions have failed to halt its weapons programme.

North Korea’s case demonstrates the NPT’s Achilles’ heel: the Article X withdrawal clause provides a legal exit ramp for states that have acquired the technical knowledge needed for nuclear weapons and then choose to cross the final threshold.

India, Pakistan, and Israel: Outside the Treaty

Three states that never joined the NPT possess nuclear weapons:

India has an estimated 164 warheads and has engaged in a tense nuclear stand-off with Pakistan for decades. The India-Pakistan relationship — involving two nuclear-armed states with a history of armed conflict, contested territory (Kashmir), and episodic military crises — is widely regarded as one of the world’s most dangerous nuclear flashpoints.
Pakistan has an estimated 170 warheads and a history of internal political instability that raises acute questions about the security of its nuclear arsenal.
Israel maintains a policy of nuclear ambiguity — neither confirming nor denying possession of nuclear weapons — while widely believed to have 80–90 warheads. Israel has never signed the NPT and has resisted all calls to join, including repeated demands from Arab states within the context of a proposed Middle East Nuclear-Weapon-Free Zone.

The existence of three nuclear-armed states outside the NPT — and the US-India Civil Nuclear Agreement (2008), which effectively legitimised India’s nuclear status outside the NPT framework — has significantly undermined the treaty’s universality and credibility.

Iran: The Enrichment Standoff

Iran’s nuclear programme has been the defining proliferation challenge of the 21st century. Iran, an NPT member state, developed a covert nuclear programme for years before it was exposed in 2002. The programme included uranium enrichment and heavy-water reactor construction activities — all potentially dual-use — which Iran maintains are entirely within its Article IV rights.

Years of negotiations produced the Joint Comprehensive Plan of Action (JCPOA) in 2015 — a landmark agreement under which Iran accepted significant restrictions on its nuclear activities in exchange for sanctions relief. The JCPOA was widely regarded as a major triumph of non-proliferation diplomacy.

In 2018, the United States unilaterally withdrew from the JCPOA under President Trump and reimposed sweeping sanctions. Iran responded by progressively abandoning its JCPOA commitments, and today enriches uranium to 60% purity — close to the 90% weapons-grade threshold. Negotiations to revive the JCPOA have stalled, and Iran’s nuclear programme is now more advanced than at any point in its history.

The Iran case illustrates both the possibilities and fragility of non-proliferation diplomacy: what years of multilateral effort achieved, a single political decision dismantled.

The New START Collapse and the End of Bilateral Arms Control

The New START Treaty (2010) — the last remaining treaty limiting US and Russian strategic nuclear arsenals — was suspended by Russia in February 2023, citing US support for Ukraine and conditions it claimed prevented equal access to verification inspections. The suspension means there is no longer any binding legal limit on the world’s two largest nuclear arsenals for the first time since the 1970s.

This is a profound setback for the NPT framework and for the cause of nuclear disarmament. Without verifiable limits on US and Russian arsenals, the Article VI disarmament process lacks even its minimal institutional scaffolding.

The Treaty on the Prohibition of Nuclear Weapons: A New Pillar or a Distraction?

In July 2017, the United Nations General Assembly adopted the Treaty on the Prohibition of Nuclear Weapons (TPNW) — also known as the Nuclear Ban Treaty — by a vote of 122 to 1. The TPNW entered into force on 22 January 2021 and has been signed by 93 states and ratified by 73 as of 2025.

The TPNW is the most radical legal development in nuclear disarmament since the NPT itself. It comprehensively prohibits:

The development, testing, production, manufacture, acquisition, possession, and stockpiling of nuclear weapons
The use or threat of use of nuclear weapons
Assisting, encouraging, or inducing any of the above activities

Not a single nuclear-armed state has signed the TPNW — nor have any states under US nuclear umbrellas (NATO members, Japan, South Korea, Australia). The US, UK, and France issued a joint statement at the time of the vote declaring they would never sign.

The TPNW debate cuts to the heart of contemporary nuclear politics. Its proponents — predominantly Global South states, civil society organisations, and survivors of nuclear weapons use and testing (the hibakusha and Pacific nuclear test survivors) — argue that the NPT’s disarmament pillar has failed and that a categorical prohibition is needed to create legal and political pressure on nuclear-armed states. Its opponents argue that the TPNW undermines the NPT by fracturing the consensus framework and ignores real-world security realities that nuclear deterrence addresses.

From a human rights perspective, the TPNW’s grounding in humanitarian law and human rights norms is compelling. Its preamble explicitly references the “catastrophic humanitarian consequences” of nuclear weapons and affirms their incompatibility with international humanitarian law. The TPNW reframes nuclear weapons not as a security asset but as a human rights crisis in waiting.

The NPT’s Relevance Today: Five Urgent Reasons

1. The Return of Great Power Nuclear Competition

The post-Cold War period of relative nuclear retrenchment is definitively over. The United States, Russia, and China are all engaged in nuclear competition simultaneously — a situation without precedent in the nuclear age. China is expanding its arsenal and building new ICBM silos at pace. Russia has developed novel nuclear delivery systems — including an intercontinental nuclear-powered cruise missile and a nuclear-capable undersea autonomous torpedo — that challenge existing arms control frameworks. The United States is modernising all three legs of its nuclear triad.

This three-way nuclear competition among great powers makes the NPT’s Article VI disarmament obligations more important — and more honoured in the breach — than at any time since the Cold War.

2. The Risk of Nuclear Use Has Increased

Multiple authoritative assessments — including from the Bulletin of Atomic Scientists, which maintains the famous Doomsday Clock — have concluded that the risk of nuclear weapons use is higher today than at any time since the Cuban Missile Crisis. The Doomsday Clock currently stands at 89 seconds to midnight (as of January 2025) — the closest to catastrophe it has ever been set.

Russia’s invasion of Ukraine was accompanied by explicit nuclear threats from senior Russian officials, including President Putin. These threats were unprecedented in the post-Cold War era and demonstrated that nuclear coercion — using the threat of nuclear weapons to deter intervention — remains a live tool of statecraft.

3. Technology and New Proliferation Risks

Advances in technology are creating new proliferation risks that the NPT’s 1968 framework was not designed to address:

Artificial intelligence: AI could accelerate missile development, improve targeting, and potentially reduce decision-making time in a crisis, increasing the risk of miscalculation
Hypersonic weapons: Hypersonic glide vehicles challenge existing missile defence systems and compress warning times, potentially increasing pressure for “launch on warning” postures
Cyber threats: Cyberattacks on nuclear command-and-control systems represent a new category of risk — a false alert generated by a cyberattack could trigger a nuclear response
Dual-use technologies: Advances in uranium enrichment and plutonium reprocessing technologies continue to lower the technical barriers to weapons development

4. The Humanitarian Imperative

The humanitarian case against nuclear weapons has never been stronger or better documented. The International Campaign to Abolish Nuclear Weapons (ICAN) — which won the Nobel Peace Prize in 2017 — and extensive academic research have documented the catastrophic consequences even a limited nuclear exchange would have:

A regional nuclear war between India and Pakistan involving 100 Hiroshima-sized bombs could kill 20 million people directly and, through agricultural disruption, cause a “nuclear famine” affecting up to 2 billion people worldwide
A large-scale nuclear exchange between the US and Russia could kill hundreds of millions directly and trigger a “nuclear winter” that collapses global agriculture, potentially threatening the survival of human civilisation

These are not science fiction scenarios — they are the documented findings of peer-reviewed scientific research. The right to life is the most fundamental of all human rights. Nuclear weapons are the most direct systematic threat to that right in existence.

5. The NPT as the Foundation of Non-Proliferation Architecture

Despite its failures, the NPT remains the cornerstone of the global non-proliferation architecture. Its near-universal membership, the IAEA safeguards system it underpins, and the normative framework it has established are irreplaceable. The alternative to a flawed NPT is not a perfect NPT — it is no NPT. And without the NPT’s framework, the non-proliferation norm that has kept nuclear weapons from spreading to dozens more states would erode rapidly.

What Must Be Done: Strengthening the NPT for the 21st Century

For Nuclear-Weapon States

Resume strategic arms control dialogue: The US and Russia must return to a framework of verifiable limits on their nuclear arsenals, building toward the New START replacement. The US and China must begin meaningful bilateral nuclear dialogue — currently, there are no binding agreements limiting Chinese nuclear forces.
Make Article VI obligations concrete: Nuclear states must commit to interim measures on the path to disarmament — including no-first-use pledges, de-alerting weapons, reducing the role of nuclear weapons in security doctrines, and establishing a timeline for disarmament negotiations.
End nuclear modernisation programmes that introduce qualitatively new capabilities, which undermine the spirit of Article VI commitments.
Ratify the Comprehensive Nuclear-Test-Ban Treaty (CTBT): The CTBT has never entered into force because eight key states — including the US, China, India, Pakistan, and others — have not ratified it. US ratification would be transformative for the global non-proliferation regime.

For Non-Nuclear-Weapon States

Maintain and strengthen the NPT: Non-nuclear states should resist the temptation to abandon the NPT framework in frustration. A world with 191 NPT members and their IAEA safeguards commitments is vastly safer than the alternative.
Use the TPNW strategically: The TPNW should be used as political leverage — a statement of the humanitarian norm that nuclear-armed states are violating — rather than as an alternative to NPT engagement.
Demand accountability mechanisms: Non-nuclear states should push for stronger compliance and accountability provisions in NPT review processes, including clearer consequences for non-compliance.

For the International Community

Support the IAEA: The IAEA remains chronically underfunded relative to its mandate. Member states must provide adequate resources for safeguards, verification, and technical cooperation.
Revive diplomacy on North Korea and Iran: Persistent diplomatic engagement — including credible security assurances and sanctions relief linked to verifiable commitments — remains the only viable path to progress on these critical proliferation challenges.
Integrate nuclear security into human rights discourse: Human rights bodies, special rapporteurs, and civil society must more consistently frame nuclear weapons as a human rights issue — as the TPNW does — to build political pressure for disarmament.
Empower civil society and survivor voices: The hibakusha — survivors of Hiroshima and Nagasaki — have provided living testimony of nuclear weapons’ human cost. Their voices, and those of Pacific nuclear test survivors, must be centred in policy debates.

The Human Rights Dimension: Nuclear Weapons Are a Human Rights Issue

The intersection of the Nuclear Non-Proliferation Treaty with human rights is not incidental — it is foundational. Nuclear weapons are uniquely incompatible with international humanitarian law and human rights for several reasons:

They are inherently indiscriminate. Under the laws of war, combatants must distinguish between military targets and civilians. Nuclear weapons cannot do so. Their blast, heat, and radiation effects spread across vast areas, killing civilians and combatants alike without distinction.

They cause superfluous suffering. International humanitarian law prohibits weapons that cause unnecessary suffering. The radiation effects of nuclear weapons — including cancers, genetic damage, and long-term environmental contamination — cause suffering that extends decades and generations beyond the moment of use.

They threaten the right to a healthy environment. Nuclear testing has contaminated vast tracts of land and ocean, disproportionately affecting Indigenous communities in the Pacific, Central Asia, the United States, and elsewhere. The Marshall Islands, Kazakhstan’s Semipalatinsk region, and Nevada’s Western Shoshone lands bear the toxic legacy of nuclear testing — a legacy that constitutes a gross and ongoing human rights violation.

They undermine the right to development. The estimated $72.6 billion spent on nuclear weapons globally in 2023 alone — a figure that rises each year — represents resources diverted from education, health, climate action, and poverty reduction.

From a human rights framework, the possession of nuclear weapons — let alone their use — is not a neutral political choice. It is a standing threat to the most fundamental rights of people who never consented to live under nuclear shadow.

Conclusion: The NPT at a Crossroads

The Nuclear Non-Proliferation Treaty is both the world’s greatest arms control achievement and its most visibly broken promise. It has prevented the spread of nuclear weapons to scores of states that might otherwise have acquired them, built a near-universal norm against nuclear weapons acquisition, and provided the framework for significant reductions in Cold War-era arsenals. These are genuine, historically significant achievements.

Yet the treaty is in crisis. The disarmament pillar has never been delivered. Great power nuclear competition is returning with dangerous intensity. North Korea has crossed the nuclear threshold and shows no sign of returning. Iran stands at the enrichment threshold. The arms control architecture that gave the NPT its operational backbone is crumbling. And the 2022 Review Conference’s failure to adopt a final document reflects an NPT consensus on the verge of collapse.

The question is not whether the NPT matters — it matters enormously, and its disappearance would be catastrophic. The question is whether the states that created it and that rely on it have the political will to honour its promises and adapt it to 21st-century realities.

On that question, the jury is still very much out. What is clear — from the perspective of international human rights, international humanitarian law, and the elementary demands of human survival — is that the world cannot afford to let the NPT fail.

Nuclear weapons are the ultimate denial of human rights. The Nuclear Non-Proliferation Treaty, for all its flaws, remains humanity’s most important legal framework for preventing that denial from becoming irreversible.

The Doomsday Clock stands at 89 seconds to midnight. It is time — far past time — to start turning it back.

Frequently Asked Questions (FAQ)

Q: What is the Nuclear Non-Proliferation Treaty (NPT)?
The NPT is an international treaty signed in 1968 and in force since 1970 that commits non-nuclear states not to acquire nuclear weapons, commits nuclear-weapon states to pursue disarmament, and ensures all states have access to peaceful nuclear technology under IAEA safeguards. It has 191 member states.

Q: Which countries are not members of the NPT?
Four states remain outside the NPT: India, Pakistan, Israel, and North Korea (which announced withdrawal in 2003). All four possess or are believed to possess nuclear weapons.

Q: Has the NPT succeeded in preventing nuclear proliferation?
Largely yes — far fewer states have nuclear weapons today than Cold War-era projections suggested. However, it has failed to prevent North Korea’s programme and faces ongoing challenges with Iran’s enrichment activities.

Q: What is Article VI of the NPT?
Article VI obligates all NPT parties — especially the five nuclear-weapon states — to pursue “negotiations in good faith” toward nuclear disarmament. Critics argue this obligation has not been fulfilled.

Q: What is the difference between the NPT and the TPNW?
The NPT (1970) manages the existence of nuclear weapons through non-proliferation and incremental disarmament commitments. The TPNW (2021) comprehensively prohibits nuclear weapons but has not been signed by any nuclear-armed state.

Q: Is India a signatory of the NPT?
No. India has never signed the NPT and possesses nuclear weapons. India argues the NPT is discriminatory because it legally entrenches the nuclear monopoly of the P5 states.

Key Takeaways

The Nuclear Non-Proliferation Treaty (NPT) is the cornerstone of the global non-proliferation regime, with 191 member states and three pillars: non-proliferation, disarmament, and peaceful use.
The NPT’s greatest achievement is the near-universal norm against nuclear weapons acquisition — dramatically fewer states possess nuclear weapons than Cold War projections suggested.
The NPT’s most serious failure is the Article VI disarmament obligation: nuclear-weapon states have made no credible progress toward the “complete disarmament” the treaty requires.
Contemporary threats include North Korea’s arsenal, Iran’s enrichment programme, the collapse of US-Russia arms control, and renewed great power nuclear competition involving China.
The TPNW (Nuclear Ban Treaty) represents a complementary humanitarian-law approach but has not been signed by nuclear-armed states.
Nuclear weapons are a human rights issue — inherently indiscriminate, incompatible with international humanitarian law, and representing a standing threat to the right to life of all people.
Strengthening the NPT requires concrete Article VI action, CTBT ratification, IAEA funding, revival of diplomacy on North Korea and Iran, and integrating nuclear disarmament into human rights advocacy.
