Nuclear brinkmanship returns: decoding the crisis in global arms control for UPSC

Introduction: A World on the Brink

Analogy Alert! The Doomsday Clock, a symbolic representation of humanity’s proximity to global catastrophe, was set in January 2025 to 89 seconds to midnight—the closest it has ever been. This unprecedented warning from the Bulletin of the Atomic Scientists is not hyperbole; it is a stark reflection of a rapidly deteriorating global security environment. The specter of nuclear conflict, once a relic of the Cold War, has returned with alarming ferocity. Russia’s repeated nuclear rhetoric during its war in Ukraine, a nation that famously surrendered its nuclear arsenal for security guarantees, has shaken the very foundations of the global nuclear order. This, coupled with China’s meteoric nuclear expansion and the crumbling of decades-old arms control treaties, has thrust the world into a new, more complex, and arguably more dangerous nuclear age.

For UPSC aspirants, understanding this paradigm shift is not just a matter of international relations; it is a critical intersection of geopolitics, science and technology, and global governance.

The Old Order: Pillars of the Non-Proliferation Regime

For over half a century, the world relied on a delicate architecture of treaties and norms to prevent the spread of nuclear weapons. The cornerstone of this regime is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) of 1968.

Think of the NPT as a Grand Bargain built on three pillars:

1. Non-Proliferation: Non-Nuclear Weapon States (NNWS) pledge not to acquire nuclear weapons.
2. Disarmament: The five original Nuclear Weapon States (NWS)—USA, Russia, UK, France, and China—commit to pursuing negotiations in good faith toward nuclear disarmament.
3. Peaceful Use: All signatory states are guaranteed access to peaceful nuclear technology for energy and development, under the supervision of the International Atomic Energy Agency (IAEA).

This bargain was supported by other key agreements, including the Comprehensive Nuclear-Test-Ban Treaty (CTBT), aimed at banning all nuclear explosions, and the Nuclear Suppliers Group (NSG), which controls the export of nuclear materials and technology. However, this old order is now facing an existential crisis.

Mnemonic for NPT-Recognized Nuclear Weapon States: Remember the five original nuclear powers with the acronym FRANC-U:

• France
• Russia
• America (USA)
• No, this is a placeholder! Let’s correct it: China
• United Kingdom

Let’s refine it: Use CRUFF:

• China
• Russia
• United Kingdom
• France
• F… America (USA). Let’s try again. A memorable phrase is better. How about: “A Big Red Fire Truck” -> America, Britain (UK), Russia, France, The People’s Republic of China. Or more simply, FRANC-U: France, Russia, America, New China, UK. Let’s stick to the clear one: FRANC-U (France, Russia, America, China, United Kingdom).

The New Instability: Recent Cracks in the Global Nuclear Order

The primary focus for understanding today’s nuclear landscape must be on the dramatic developments of the last two years.

The Ukraine Effect: The Peril of Disarmament

Ukraine’s 1994 decision to surrender the world’s third-largest nuclear arsenal in exchange for security assurances under the Budapest Memorandum is now seen as a tragic strategic error. Russia’s invasion has sent a chilling message: security guarantees from nuclear powers are unreliable, and possessing a nuclear deterrent is the only credible shield against aggression. This has dangerously bolstered the case for proliferation in countries like Japan, South Korea, and Taiwan, who live in increasingly tense neighborhoods.

The End of Arms Control: Russia’s New START Suspension

In a landmark blow to global stability, Russian President Vladimir Putin announced the suspension of Russia’s participation in the New START Treaty in February 2023. This was the last remaining bilateral nuclear arms control treaty between the U.S. and Russia, limiting deployed strategic warheads and bombs. The suspension halts on-site inspections and data exchanges, effectively ending mutual verification. With the treaty set to expire in 2026 without a successor, the world faces the prospect of zero constraints on the world’s two largest nuclear arsenals for the first time since 1972.

The Dragon’s Arsenal: China’s Breakneck Expansion

Perhaps the most significant long-term shift is China’s opaque and rapid nuclear buildup. According to the U.S. Pentagon’s 2024 report, China has likely amassed over 600 operational nuclear warheads and is on track to possess over 1,000 by 2030. The Stockholm International Peace Research Institute (SIPRI) noted in its 2024 yearbook that China’s arsenal grew from 410 to 500 warheads in just one year, the fastest expansion rate of any country. This is a monumental shift from China’s historical doctrine of Minimum Deterrence. Beijing is now developing a full nuclear triad (land-based ICBMs, submarine-launched ballistic missiles, and strategic bombers) and potentially moving towards a ‘launch-on-warning’ posture, dramatically increasing the risk of miscalculation.

Fun Fact: As of early 2024, the nine nuclear-armed states possessed an estimated 12,121 nuclear warheads. While this is down from the Cold War peak, the number of operational warheads in military stockpiles is now increasing year-on-year.

A New Path or a Dead End? The TPNW

In response to the perceived failures of the NPT’s disarmament pillar, a new international agreement emerged: the Treaty on the Prohibition of Nuclear Weapons (TPNW). It entered into force in January 2021 and represents the first legally binding international agreement to comprehensively prohibit nuclear weapons.

As of September 2025, 74 states have ratified or acceded to the treaty. However, its impact is limited as all nine nuclear-armed states and all NATO members (except for one vote) have boycotted it. They argue that it ignores the security realities that make deterrence necessary. The TPNW thus creates a normative divide: a large group of nations has declared nuclear weapons illegal, while a smaller, powerful group insists on their strategic necessity.

Critical Policy Appraisal

--- ""

Analytical Lens: UPSC Focus (Mains & Prelims)

• Conceptual Basis: The foundational legal instrument is the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), 1968. The most recent major legal development is the Treaty on the Prohibition of Nuclear Weapons (TPNW), 2017, which entered into force in 2021.

• UPSC Integration: Connecting the Dots

  • Polity & Governance (GS Paper 2): India’s foreign policy is deeply intertwined with its nuclear posture. This includes its ‘Credible Minimum Deterrence’ and ‘No First Use’ (NFU) policy. While India is not a signatory to the NPT, viewing it as discriminatory, it adheres to its core principles and engages with export control regimes like the NSG.
  • Science & Technology (GS Paper 3): Understanding the technology of a nuclear triad, development of Intercontinental Ballistic Missiles (ICBMs) like the Agni series, Submarine Launched Ballistic Missiles (SLBMs) for second-strike capability (INS Arihant), and the role of fissile materials (plutonium, enriched uranium) are crucial.
  • Modern Indian History (GS Paper 1): The historical context of India’s nuclear tests (1974 and 1998) is linked to post-independence security challenges and India’s quest for strategic autonomy, influenced by the Non-Aligned Movement’s stance on global disarmament.

• Future Impact & Policy Relevance: The world is entering a tripolar nuclear era dominated by the US, Russia, and China. This is inherently less stable than the bipolar Cold War dynamic. The focus for India will be to maintain its credible minimum deterrence in the face of China’s rapid expansion and Pakistan’s tactical nuclear weapons development. India’s policy will likely involve continued modernization of its delivery systems while championing universal, non-discriminatory disarmament on the global stage.

Practice Question (Prelims)

Which of the following statements correctly describes India’s position with respect to the global nuclear regime?

1. India is a signatory to the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) as a Non-Nuclear Weapon State.
2. India has ratified the Comprehensive Nuclear-Test-Ban Treaty (CTBT) and observes a voluntary moratorium on testing.
3. India has a declared ‘No First Use’ policy but is not a party to the Treaty on the Prohibition of Nuclear Weapons (TPNW).
4. India’s nuclear program is under the full-scope safeguards of the International Atomic Energy Agency (IAEA).

Correct Answer: 3

Explanation: India considers the NPT discriminatory and has not signed it. It has also not signed or ratified the CTBT, though it observes a unilateral moratorium on testing. India’s official doctrine is ‘No First Use’ (NFU), and like other nuclear powers, it has boycotted the TPNW. Only its civilian nuclear facilities are under IAEA safeguards, not its entire program. Therefore, statement 3 is the only correct one.

Practice Question (Mains)

(15 Marks, 250 Words)

The collapse of Cold War-era arms control treaties and the rise of new nuclear powers have fundamentally challenged the global non-proliferation regime. Critically analyze the reasons for the erosion of the NPT framework and discuss the implications for India’s strategic autonomy and security policy.
