Critically evaluate the role of international treaties in regulating nuclear arsenals. How does the weakening of arms-control frameworks affect global peace and security?

Introduction

Since the advent of nuclear weapons, international arms-control treaties have sought to reduce the risks of nuclear war, prevent proliferation, and promote strategic stability. Agreements such as the Nuclear Non-Proliferation Treaty (NPT), Comprehensive Nuclear-Test-Ban Treaty (CTBT), New START, and various regional arrangements have established norms governing nuclear arsenals. However, geopolitical rivalries, technological advancements, and the erosion of arms-control mechanisms have weakened these frameworks, posing significant challenges to global peace and security.

Role of International Treaties in Regulating Nuclear Arsenals

1. Preventing Nuclear Proliferation

• The NPT (1968) seeks to prevent the spread of nuclear weapons while promoting peaceful uses of nuclear energy.
• Strengthens the global non-proliferation regime through International Atomic Energy Agency (IAEA) safeguards.

2. Limiting Nuclear Arms Race

• Bilateral treaties such as New START (2010) place verifiable limits on deployed strategic nuclear weapons.
• Promote transparency and confidence-building between major nuclear powers.

3. Promoting Nuclear Disarmament

• Arms-control agreements reinforce the long-term objective of reducing global nuclear stockpiles.
• Encourage dialogue and negotiated reductions.

4. Building Strategic Stability

• Verification mechanisms, inspections, and data exchanges reduce uncertainty and the risk of miscalculation.

5. Establishing International Norms

• Treaties create legal and political norms against nuclear testing and proliferation.
• CTBT (1996) has established a strong global norm against nuclear explosive testing despite not entering into force.

Limitations of International Arms-Control Frameworks

1. Incomplete Participation

• Not all nuclear-armed states are parties to key treaties or accept identical obligations.
• The NPT distinguishes between nuclear-weapon and non-nuclear-weapon states, leading to concerns about unequal obligations.

2. Weak Enforcement

• Compliance depends largely on political commitment.
• Enforcement mechanisms are often constrained by geopolitical considerations.

3. Technological Developments

• Hypersonic weapons, cyber capabilities, autonomous systems, and space technologies are inadequately covered by existing treaties.

4. Geopolitical Rivalries

• Strategic competition among major powers reduces willingness to negotiate new agreements.

Impact of Weakening Arms-Control Frameworks

1. Renewed Arms Race

• Countries may expand and modernise nuclear arsenals without agreed limitations.

2. Increased Strategic Instability

• Reduced transparency increases mistrust and the risk of miscalculation during crises.

3. Greater Risk of Nuclear Escalation

• Absence of confidence-building measures may lower the threshold for conflict escalation.

4. Weakening of Non-Proliferation Norms

• Declining confidence in treaties may encourage proliferation by additional states.

5. Increased Global Security Risks

• Expansion of missile defence, hypersonic systems, and tactical nuclear weapons complicates deterrence dynamics.

6. Challenges for Multilateral Governance

• Weakens the credibility of international institutions involved in arms control and disarmament.

Measures Required

1. Revitalise Arms-Control Dialogue

• Resume bilateral and multilateral negotiations among nuclear powers.

2. Expand Treaty Coverage

• Develop frameworks addressing emerging technologies such as hypersonic weapons, cyber threats, AI, and space security.

3. Strengthen Verification

• Enhance transparency through inspections, satellite monitoring, and confidence-building measures.

4. Reinforce the IAEA

• Strengthen safeguards, monitoring, and peaceful nuclear cooperation.

5. Promote Universal Commitment

• Encourage broader participation in global non-proliferation and arms-control initiatives.

6. Strengthen Crisis Communication

• Expand military hotlines, risk-reduction mechanisms, and strategic dialogue.

India's Perspective

• India follows a policy of Credible Minimum Deterrence and No First Use (NFU).
• India is not a signatory to the NPT, considering it discriminatory, but has maintained a strong non-proliferation record.
• India supports universal, non-discriminatory, and verifiable nuclear disarmament.

Conclusion

International treaties have played a vital role in reducing nuclear risks, promoting strategic stability, and establishing global norms against proliferation. However, the weakening of arms-control frameworks amid intensifying geopolitical competition and emerging military technologies threatens to undermine decades of progress. Revitalising multilateral arms-control efforts, strengthening verification mechanisms, and adapting legal frameworks to contemporary security challenges are essential for preserving global peace and preventing a renewed nuclear arms race.

Value Addition (Global Governance Perspective): Sustainable international security requires a balance between credible deterrence and effective arms control, as technological superiority without cooperative restraint increases the risks of miscalculation, escalation, and global instability.
