More than half a century since its signing, the Treaty on the Non-Proliferation of Nuclear Weapons remains the cornerstone of global nuclear diplomacy—yet it sits on increasingly fragile ground. Rising geopolitical tensions and rapidly modernizing military technologies have resurfaced global anxieties surrounding nuclear parity and strategic ambiguity. SunMUN XVI invites General Assembly delegates to critically examine the contemporary relevance of the Treaty, its enforcement mechanisms, and the broadening diplomatic differences between nuclear states and non-nuclear signatories. In a new world for diplomacy, the General Assembly must decide whether the treaty remains an instrument of collective security or a replacement-necessitating relic of the twentieth century.

Alongside addressing nuclear weapons proliferation, delegates must be prepared to discuss the illicit trafficking of fissile materials. These nuclear materials present growing security and environmental hazards, particularly in conflict zones: integral to negotiating these jeopardies will be confronting the unseen mechanisms behind unsecured nuclear stockpiles and, in particular, emerging nuclear threats posed by non-state actors. Delegates must reconcile state sovereignty with global safety, and act decisively to address these twenty-first century dangers.
