The Fraying Nuclear Order: Why the Non-Proliferation Treaty is in Crisis and What it Means for India

The global nuclear non-proliferation regime, for decades a cornerstone of international security, is facing a significant test of its credibility. The principles of the Non-Proliferation Treaty (NPT) are being challenged by the actions of both nuclear and non-nuclear states, raising fundamental questions about its fairness and effectiveness. The ongoing standoff with Iran serves as a prominent symptom of this deeper challenge.

What is the NPT's 'grand bargain' and why is it breaking down?

The NPT, which entered into force in 1970, is built on three pillars: non-proliferation, disarmament, and the right to peacefully use nuclear technology. The treaty's core is a bargain: the 186 Non-Nuclear Weapon States (NNWS) party to the treaty pledge not to acquire nuclear weapons. In return, the five recognized Nuclear Weapon States (NWS)—the U.S., Russia, UK, France, and China—are obligated under Article VI of the NPT 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.”

This bargain is fraying for two key reasons. First, the disarmament pillar has seen little progress. The NWS continue to modernize their arsenals, with an estimated 12,100 total warheads among them as of early 2024, according to the Federation of American Scientists. This lack of progress is seen by many NNWS as a breach of faith. Second, the treaty institutionalized a fundamental inequality. As noted by analysts, it divided the world into nuclear 'haves' and 'have-nots' based on the cut-off date of January 1, 1967, creating a permanent hierarchy rather than a clear pathway to universal disarmament.

How does the Iran case highlight the regime's contradictions?

The confrontation over Iran's nuclear program is a case study in the NPT regime's internal contradictions. Iran, a signatory to the NPT, has consistently maintained its right to enrich uranium for peaceful purposes under Article IV of the treaty. The 2015 Joint Comprehensive Plan of Action (JCPOA) was designed to manage this by placing Iran's program under an intrusive inspections regime in exchange for lifting international sanctions.
