Disarmament and International Security Committee

The Disarmament and International Security Committee (DISEC), formally known as the First Committee of the United Nations General Assembly, is a primary deliberative body tasked with addressing global threats to peace, security, and the regulation of armaments. Established in 1945 alongside the UN Charter, it holds a longstanding mandate to promote international stability by fostering disarmament and preventing the proliferation of weapons, ranging from small arms to weapons of mass destruction. Unlike the Security Council, DISEC is a universal body where all 193 member states are represented, making it a critical forum for building international consensus on complex security issues.

In 2026, DISEC remains at the forefront of tackling both traditional security challenges and emerging, technology-driven risks, including cyber warfare, artificial intelligence in military applications, and the militarization of outer space. The committee plays a vital role in drafting resolutions and recommendations that often serve as the foundation for future international treaties and norms. In an increasingly fragmented global landscape, delegates in DISEC work in close collaboration with bodies like the UN Office for Disarmament Affairs (UNODA) to formulate comprehensive policies that balance national defense needs with global security obligations.

Today, you will be at the forefront of two issues that sit at the bleeding edge of international security law: the absence of binding regulation on machines that can decide to kill, and the accelerating spread of nuclear ambitions to states that have historically remained on the threshold. Both issues share a common disease (regulatory paralysis driven by great power disagreement) and a common urgency: the window for preventive action is closing.
