A START For Multilateralism: Nuclear Proliferation Needs A Global Treaty

A START for Multilateralism: Why Nuclear Proliferation Needs a Global Treaty

The expiry of the New Strategic Arms Reduction Treaty (New START) signals a discouraging moment in global nuclear governance. This development highlights the inadequacies of bilateral frameworks in addressing the increasingly multipolar and technologically advanced nuclear landscape. A shift toward multilateralism in nuclear arms control, grounded in regional threat mitigation and global verification mechanisms, is an urgent imperative. The conceptual framework underlying this analysis is "multilateral vs bilateral arms control" in international relations.

Institutional Landscape: Legal and Governance Framework

The nuclear arms control regime has historically relied on bilateral agreements, such as START-I (1991) and New START (2010), primarily between the United States and Russia. However, emerging threats, including regional nuclear ambitions and advances in hypersonic and AI-enabled systems, demand global mechanisms. Multilateral treaties such as the Treaty on the Prohibition of Nuclear Weapons (TPNW) 2017 and the Non-Proliferation Treaty (NPT) provide a baseline, but exclusions of leading nuclear states undermine their efficacy.

• Legal instruments: NPT (1968), SORT Treaty (2002), New START Treaty (2010)
• Institutions: United Nations, IAEA, Stockholm International Peace Research Institute (SIPRI)
• Provisions under review: NPT disarmament obligations, TPNW sanctions mechanisms

Key Data and Arguments Supporting Multilateralism

Authoritative sources suggest increasing nuclear risk. SIPRI's 2025 data reveals that nine nuclear-armed states hold a combined 12,241 warheads, and efforts by China and Pakistan are rapidly expanding arsenals. The erosion of transparency mechanisms like New START has opened pathways for miscalculation and crisis escalation. For example, SIPRI highlights that China is constructing hundreds of missile silos alongside regional hotspots in East Asia.

• SIPRI's January 2025 estimate: China possesses roughly 600 warheads, with the fastest growth globally.
• India has overtaken Pakistan with approximately 180 operational warheads, intensifying regional security concerns.
• The NPT framework obliges 191 member states to pursue disarmament, but enforcement remains weak.

Counter-Narrative: Bilateral Frameworks and Security Pragmatism

Critics argue multilateral mechanisms dilute strategic autonomy and create interminable negotiations. Bilateral treaties like START-I and New START have historically delivered substantive reductions. Proponents of bilateralism contend that multilateral frameworks, such as the TPNW, suffer from limited enforceability, as none of the nine nuclear powers have signed or ratified it. From a realist lens, bilateral mechanisms focus resources where they are most impactful—on the dominant arsenals of the US and Russia.

International Comparison: Multilateralism in Arms Control

To assess the feasibility of multilateral approaches, it is useful to examine the global disarmament initiatives led by nations like South Africa, which voluntarily relinquished nuclear capabilities under the NPT umbrella. South Africa’s approach demonstrates the potential success of multilateral disarmament with structured incentives and international verification mechanisms.

Structured Assessment

• Policy design adequacy: Existing treaties like NPT need modernization for enforceable commitments, especially incorporating advanced technologies.
• Governance capacity: Multilateral efforts must scale verification mechanisms using AI, remote sensing, and IAEA oversight.
• Behavioral and structural factors: National security ambitions and hyper-nationalist discourses often obstruct cooperation; robust Track II dialogues can temper such tendencies.
