What is Credible Minimum Deterrence?
Historical Background
Key Points
13 points- 1.
The core of Credible Minimum Deterrence is the 'second-strike capability'. This means even if a nation is attacked first, it must have enough surviving nuclear weapons and delivery systems (like submarines or missiles) to retaliate and inflict unacceptable damage on the attacker. Without this, the deterrent is not credible.
- 2.
A 'No First Use' (NFU) policy is often associated with Credible Minimum Deterrence. India has declared an NFU policy, meaning it will only use nuclear weapons in retaliation for a nuclear attack on Indian territory or on Indian forces anywhere. This reduces the risk of accidental escalation.
- 3.
The 'minimum' aspect is crucial. It means maintaining the smallest possible nuclear arsenal consistent with credible deterrence. This reduces the cost of maintaining the arsenal, the risk of proliferation, and the likelihood of accidental use.
- 4.
Credibility depends on several factors: the survivability of nuclear forces, the reliability of delivery systems, and the will to use them in retaliation. A nation must demonstrate its commitment to using nuclear weapons under certain circumstances to deter potential aggressors.
- 5.
Command and Control systems are vital. A nation must have secure and reliable systems to control its nuclear weapons and ensure they are only used under authorized orders. This prevents accidental or unauthorized use.
- 6.
Intelligence and Surveillance are essential for assessing threats and maintaining situational awareness. A nation must be able to detect and track potential adversaries and their nuclear capabilities.
- 7.
The doctrine is not static. It evolves with changes in technology, the geopolitical environment, and the capabilities of potential adversaries. Continuous assessment and adaptation are necessary to maintain its effectiveness.
- 8.
Transparency, to a limited extent, can enhance credibility. While secrecy is important for security, some degree of openness about nuclear capabilities and doctrine can reassure allies and deter adversaries.
- 9.
A key challenge is maintaining credibility against a larger nuclear power. A smaller nuclear power must convince a larger power that even a limited retaliatory strike would inflict unacceptable damage, making an attack not worth the cost.
- 10.
The concept differs from Mutual Assured Destruction (MAD). MAD relies on having enough nuclear weapons to completely destroy an adversary, while Credible Minimum Deterrence relies on having enough to inflict unacceptable damage. MAD requires a much larger and more expensive arsenal.
- 11.
In practice, Credible Minimum Deterrence means investing in survivable delivery systems like nuclear submarines (SSBNs), which are difficult to detect and destroy. This ensures a second-strike capability.
- 12.
A potential weakness is the risk of miscalculation. An adversary might underestimate a nation's resolve or capability, leading to a misjudgment that could trigger a nuclear exchange. Clear communication and signaling are essential to mitigate this risk.
- 13.
The UPSC examiner often tests the nuances of the 'No First Use' policy, the technological requirements for maintaining a credible deterrent, and the ethical considerations of nuclear weapons. They also test the differences between Credible Minimum Deterrence and other nuclear doctrines.

Recent Developments
6 developmentsIn 2016, India's first indigenous nuclear submarine, INS Arihant, completed its first deterrence patrol, significantly enhancing India's second-strike capability.
In 2018, India successfully tested the Agni-V intercontinental ballistic missile (ICBM), which can reach all of China, further solidifying its deterrent.
In 2020, the Cabinet Committee on Security (CCS) reviewed India's nuclear doctrine and reaffirmed its commitment to Credible Minimum Deterrence and No First Use.
In 2022, India conducted a successful test of the Agni Prime, a new generation medium-range ballistic missile, showcasing its technological advancements in missile technology.
In 2023, discussions within strategic circles have focused on the need to adapt India's nuclear doctrine to address evolving threats, including those in the cyber domain, while maintaining the core principles of Credible Minimum Deterrence.
In 2024, India continues to invest in its nuclear triad (land-based missiles, submarine-launched missiles, and air-launched missiles) to ensure the survivability and credibility of its nuclear deterrent.

1 topicsFrequently Asked Questions
61. What's the most common MCQ trap regarding 'No First Use' (NFU) and Credible Minimum Deterrence?
The most common trap is assuming NFU is *required* for Credible Minimum Deterrence. While India has both, they are distinct. A nation *can* have Credible Minimum Deterrence without an NFU policy. Examiners often present options implying NFU is a defining characteristic, which is incorrect. Credible Minimum Deterrence focuses on second-strike capability and unacceptable damage, regardless of who strikes first.
Exam Tip
Remember: Credible Minimum Deterrence = Second-strike capability + Unacceptable Damage. NFU is a *policy choice*, not a *requirement*.
2. Credible Minimum Deterrence aims to deter. But what if deterrence fails? What then?
This is a critical point often overlooked. Credible Minimum Deterrence primarily focuses on *preventing* nuclear war through the threat of retaliation. If deterrence fails, the doctrine provides little guidance beyond inflicting 'unacceptable damage'. The actual response – the scale, targets, and conditions for de-escalation – are left ambiguous. Critics argue this ambiguity can lead to miscalculation and escalation, especially if command and control are compromised.
3. How does India's 'No First Use' policy affect the credibility of its minimum deterrence?
India's NFU policy presents a double-edged sword. Some argue it *weakens* deterrence because a potential aggressor might believe India would hesitate to retaliate, especially if the initial attack is devastating. Others argue it *strengthens* deterrence by signaling India's commitment to responsible nuclear behavior, reducing the risk of accidental escalation and reassuring other nations. The credibility then hinges on the survivability of India's second-strike capability, like the INS Arihant, and the perceived resolve to use it.
4. What are the key components that make India's Credible Minimum Deterrence actually 'credible'?
Credibility isn't automatic; it depends on several factors. UPSC often tests these:
- •Second-Strike Capability: The ability to retaliate even after absorbing a first strike. INS Arihant is crucial here.
- •Reliable Delivery Systems: Missiles like Agni-V must function as intended. Continuous testing is essential.
- •Secure Command and Control: Preventing unauthorized use is paramount. Robust systems are needed.
- •Political Will: The adversary must believe India *will* retaliate if attacked. This is about signaling resolve.
- •Intelligence and Surveillance: Accurate threat assessment is vital for effective deterrence.
Exam Tip
Memorize: Second-Strike, Delivery, Command, Will, Intelligence. These are the pillars of credibility.
5. How has the rise of cyber warfare impacted the 'Credible' aspect of India's nuclear deterrence?
Cyber warfare introduces a new dimension of vulnerability. A sophisticated cyber attack could potentially: (1) Disrupt command and control systems, (2) Degrade intelligence and surveillance capabilities, (3) Even interfere with the functioning of delivery systems. This challenges the 'credibility' of India's deterrence because it raises doubts about the survivability and reliability of its nuclear forces. Addressing this requires integrating cyber defenses into nuclear strategy and developing resilient systems.
6. The Agni-V ICBM test in 2018 was significant. But what specific aspect of it is MOST relevant to Credible Minimum Deterrence, and why?
The *range* of the Agni-V is the most relevant aspect. Its ability to reach all of China significantly enhances India's second-strike capability and, therefore, its credible minimum deterrence. Because a retaliatory strike against China is a core element of India's deterrence posture, a missile that can reliably reach all potential targets is crucial. Other aspects, like accuracy improvements, are secondary to the range in this context.
Exam Tip
When asked about Agni-V and deterrence, focus on its *range* as the primary factor for credibility.
