The Disarmament and International Security Committee (DISEC) deals with issues regarding nuclear disarmament, conventional arms control, regional conflicts, terrorism, and emerging threats like cyber security. The resolutions passed by the committee lay the framework for many international treaties and agreements. The committee focuses on formulating plans for international stability and global security through disarmament and world peace.
Delegates in this committee explore topics ranging from nuclear disarmament and terrorism to cyberattacks and the use of artificial intelligence as a weapon. Delegates learn about international security, the role of non-state actors, security strategies and proposing solutions to pressing conflicts.
Delegates must evaluate whether to pursue a ban, impose limitations, or establish standards for meaningful human control. Another focus is dual-use AI, where civilian technologies can be easily repurposed for military applications, complicating export controls and verification.
Additionally, AI-driven cyber operations, autonomous drones, hypersonic systems and quantum technologies challenge existing international law and create new vulnerabilities.
Geopolitical dynamics further complicate regulation, with major powers prioritising strategic advantage and developing states emphasizing equitable access to technology. DISEC’s role is to build consensus on norms, transparency measures, accountability frameworks and cooperative mechanisms that reduce risks while enabling responsible innovation. The objective is to prevent misuse and preserve international peace and security.
The agenda focuses on one of the most pressing global security threats: the possibility that terrorist groups could acquire, construct, or deploy nuclear or radiological weapons. While building a full nuclear device requires significant resources, radiological materials used widely in medicine, industry and research are far more accessible and can be exploited to create Radiological Dispersal Devices (RDDs). Even without mass casualties, such attacks would cause severe economic disruption, long-term contamination and public panic.
DISEC must address vulnerabilities within the global nuclear security infrastructure, including weak physical protection of radioactive sources, gaps in border control, illicit trafficking networks and limited technical capacity in developing states.
