Q. Examine the significance of nuclear-weapon-free zones like the Treaty of Rarotonga in the context of major-power military signalling in the Pacific. (15 marks, 250-350 words)

The Treaty of Rarotonga (signed 1985, in force 1986) created the South Pacific Nuclear Free Zone, stretching from Australia's west coast to the Latin American zone and from the equator to 60°S [1]. China's submarine-launched ballistic missile test into the Pacific on 6 July 2026 [3] tests whether such zones still restrain major-power signalling.

Normative and legal significance - Zones convert global NPT obligations into binding regional commitments — no manufacture, possession or control of nuclear weapons, and prevention of testing on parties' territories [1]. - Rarotonga uniquely bars dumping of radioactive waste, a response to the region's history of atmospheric testing [1]. - Protocols invite the five nuclear-weapon States to give negative security assurances — not to use or threaten nuclear weapons against zone members [2]. - They anchor a regional identity of non-nuclear status, giving small island states collective diplomatic weight they lack individually [4].

Limits exposed by major-power signalling - Zones bind parties, not external powers, whose obligations flow only through protocols with varying ratification [2]. - A missile transiting to or landing in zone waters violates no clear rule, yet erodes the zone's political intent — legality and legitimacy diverge. - Advance notification of the 2026 test was given, but the absence of a standing ballistic-missile launch notification agreement left interpretation to guesswork, drawing criticism from Australia, New Zealand and Japan [3]. - Zones cover territory and testing, not transit, deterrence patrols or sea-based second-strike platforms — the very instruments now used for signalling.

Way forward - Universal ratification of zone protocols without reservations [2]; extension of pre-launch notification regimes to the Pacific [3]; and zone-to-zone cooperation to build a shared non-nuclear norm [4].

Rarotonga remains valuable less as a physical shield than as a normative benchmark against which such tests are judged and condemned. Strengthening it through protocol adherence and confidence-building measures serves India's own interest in a rules-based, stable Indo-Pacific consistent with its long-standing advocacy of universal, non-discriminatory disarmament.
