Model UN Background Guide

Committee: Disarmament and International Security Committee (DISEC/GA1)

Topic: Small Arms and Light Weapons Proliferation

Conference Year: 2026

1. Topic Background

Small arms and light weapons (SALW) proliferation remains one of the most pressing security challenges worldwide. These weapons—ranging from handguns, rifles, and machine guns to grenades and portable launchers—are responsible for the majority of deaths in armed conflicts and criminal violence globally. Historically, the widespread availability of SALW has fueled conflicts, undermined peace processes, and perpetuated cycles of violence, especially in fragile states and regions affected by insurgency or organized crime.

The issue gained significant international attention in the 1990s, following the end of the Cold War, when large stockpiles of weapons flooded post-conflict zones and illicit arms markets expanded. Since then, the global community has sought to regulate and reduce the illicit trade and uncontrolled spread of SALW through various treaties, programs, and initiatives.

The topic’s presence on the DISEC agenda in 2026 is driven by several contemporary factors:

• The ongoing conflicts in regions such as the Sahel, the Horn of Africa, and parts of Latin America continue to be exacerbated by the easy access to SALW.
• Technological advancements have made some light weapons more lethal and easier to manufacture, including 3D-printed firearms and improvised modifications.
• The rise of non-state armed groups and transnational criminal organizations has increased demand for SALW, complicating efforts to control their proliferation.
• Recent reports indicate that post-conflict disarmament, demobilization, and reintegration (DDR) programs are struggling to keep pace with the rate at which weapons circulate.
• The international community is also increasingly concerned about the link between SALW proliferation and terrorism financing, human trafficking, and other illicit activities.

As such, DISEC must address not only the supply side of SALW but also demand drivers, control mechanisms, and the implementation gaps in existing frameworks.

2. Key Actors

States:

• United States: A major producer and exporter of SALW, the U.S. plays a critical role in international arms control discussions. It emphasizes national sovereignty but supports responsible arms export controls and combating illicit trafficking.
• Russia: Another leading arms exporter, Russia advocates for state-centric control measures and often stresses the role of arms transfers in legitimate self-defense and security cooperation.
• China: Increasingly influential in arms markets, China promotes non-interference but has shown interest in multilateral frameworks to curb illicit flows.
• European Union Member States: Collectively, the EU pushes for stringent export controls, transparency, and support for post-conflict disarmament efforts.
• African Union (AU) Member States: Many African states are both victims and transit points for illicit SALW. The AU has developed regional instruments like the Bamako Declaration to address proliferation.
• Middle Eastern States: Countries in this region face complex security environments with numerous armed groups, making SALW control challenging. Some Gulf States are significant arms importers and exporters.

International Organizations (IOs):

• United Nations Office for Disarmament Affairs (UNODA): Coordinates UN efforts on arms control, including SALW.
• UN Programme of Action on Small Arms (PoA): A key multilateral framework aiming to prevent, combat, and eradicate the illicit trade of SALW.
• International Tracing Instrument (ITI): Facilitates tracing of illicit SALW to their source.
• United Nations Development Programme (UNDP): Supports DDR and community stabilization programs that reduce SALW demand.
• Regional Organizations: African Union, Organization of American States (OAS), and others have regional action plans and monitoring mechanisms.

3. Bloc Positions

Western Bloc (United States, Canada, EU, Australia, Japan)

• Strong advocates for robust export control regimes and transparency measures.
• Emphasize the importance of international cooperation and capacity-building for states affected by SALW proliferation.
• Support comprehensive implementation of the PoA and ITI.
• Often promote linking SALW control with broader counter-terrorism and organized crime efforts.

Russian-Chinese Bloc

• Stress respect for state sovereignty and non-interference in internal affairs.
• Prioritize legitimate arms transfers for national defense and security cooperation.
• Skeptical of overly restrictive measures that could limit arms trade or affect state security.
• Support dialogue but cautious about binding international instruments that infringe on national prerogatives.

African and Latin American States

• Focus on the humanitarian and security impacts of illicit SALW on peace and development.
• Advocate for international assistance in capacity-building, border control, and DDR programs.
• Call for addressing root causes such as poverty, weak governance, and corruption.
• Some states push for regional solutions and greater UN support for implementation.

Middle Eastern and South Asian States

• Concerned about the destabilizing effect of illicit SALW in ongoing conflicts and insurgencies.
• Often emphasize the need to control arms flows from external sources fueling local violence.
• Some states highlight the role of SALW in terrorism and advocate for stronger international cooperation.
• Others may resist measures perceived as limiting their defense capabilities or political autonomy.

4. Past UN Action

• Programme of Action to Prevent, Combat and Eradicate the Illicit Trade in Small Arms and Light Weapons in All Its Aspects (PoA), adopted in 2001, remains the foundational document guiding global SALW control efforts.
• International Tracing Instrument (ITI), endorsed in 2005, established mechanisms for tracing illicit SALW.
• Multiple General Assembly resolutions reaffirming commitments to SALW control, including biennial reviews of PoA implementation.
• Security Council resolutions addressing SALW proliferation in specific conflict zones (e.g., in West Africa, the Great Lakes region, and the Middle East), often linking arms embargoes to peacekeeping mandates.
• Reports by the UN Secretary-General and panels of experts regularly highlight challenges and recommend measures to improve SALW control and disarmament.

5. Questions a Resolution Should Answer

1. How can the international community enhance the implementation and enforcement of existing instruments like the PoA and ITI?
2. What measures can be taken to improve transparency and accountability in legal SALW transfers without infringing on state sovereignty?
3. How can support for capacity-building and technical assistance be scaled up for states most affected by illicit SALW proliferation?
4. What role should regional organizations play in complementing UN efforts to control SALW?
5. How can the linkages between SALW proliferation and other transnational threats such as terrorism, organized crime, and human trafficking be addressed effectively?
6. What strategies can be developed to control emerging technologies that facilitate the production and distribution of SALW, including 3D printing?
7. How can disarmament, demobilization, and reintegration (DDR) programs be strengthened to reduce the availability of SALW in post-conflict settings?

6. Further Reading

• UN Documents: Official reports and resolutions from the General Assembly, Security Council, UNODA, and the Biennial Meeting of States on the PoA provide authoritative insights into the global framework and ongoing challenges. These documents include implementation reports, Secretary-General’s assessments, and panel of experts’ findings.

• Think-Tank Reports: Research institutions such as the Small Arms Survey, Stockholm International Peace Research Institute (SIPRI), and the International Institute for Strategic Studies (IISS) offer in-depth analyses, data-driven studies, and policy recommendations on SALW proliferation trends, impacts, and control measures. These reports often explore regional dynamics and emerging technologies.

• News Outlets and Media: International news organizations (e.g., Reuters, Al Jazeera, BBC) and specialized security publications provide up-to-date coverage of conflicts, arms trafficking interdictions, and diplomatic developments related to SALW. These sources help contextualize the human and political dimensions of the issue in real time.

This background guide aims to equip delegates with a comprehensive understanding of the complexities surrounding small arms and light weapons proliferation, enabling informed debate and effective resolution drafting in DISEC 2026.
