                        Our dream of peace is in peril. The threat of nuclear weapons use is the highest in decades. Global tensions are pushing military spending to stratospheric levels. Small arms and light weapons are proliferating. And emerging technologies are making conflicts even deadlier. We must lower the temperature. On this International Day for Disarmament and Non-Proliferation Awareness, I urge leaders to step back from the brink. Stop rattling the nuclear saber. Halt the arms races. It’s time to invest in the architecture of peace, not the tools of war. That means living up to disarmament obligations. Rebuilding trust. And strengthening the systems and tools that prevent the proliferation, testing and use of deadly weapons. Together, we can prevent catastrophes and ensure a safe and peaceful world for all. António Guterres, United Nations Secretary-General.

Multilateral disarmament negotiations under United Nations auspices have traditionally sought consensual outcomes, regardless of the specific formal decision-making rules governing particular bodies. The preference for consensus is rooted in the legitimacy it is perceived to confer in matters of security — the fundamental concern of States. Because disarmament is directly linked to international security and, by extension, national security, many States have considered consensual decisionmaking essential to producing outcomes that are both credible and implementable. Reflecting this approach, consensus decision-making was seen as essential to negotiations and deliberations in two of the three main disarmament bodies recognized in 1978 by the General Assembly at its first special session devoted to disarmament. The outcome document affirmed the central role of consensus — particularly in the realm of nuclear disarmament negotiations — and the priority States attached to it. The United ...

Consensus is generally understood as a decision-making procedure characterized by the absence of objection. In multilateral disarmament negotiations , however, “consensus” carries a particular nuance that distinguishes it from “unanimity”. In practical terms, consensus is reached when no State formally objects to a decision, including by requesting a vote. Importantly, “joining consensus” does not necessarily mean that a State agrees with every element of the text or outcome. It is entirely possible — and often the case — that a State joins consensus to adopt the text while maintaining specific reservations or substantive concerns. In this context, “ explanations of vote ” are an important tool for making consensus work in practice, allowing States to place reservations on the record without rejecting the outcome as a whole (see box 4). Explanations of vote may also be used to clarify why a State voted against a decision or chose to abstain. In some instances, States explicitly note ...
