The Disarmament and International Security Committee (DISEC) is the first committee at the General Assembly of the United Nations. The committee was formed in 1945 when the Charter of the United Nations came into force, and has since been assigned to the role of maintaining international peace and security. 

Today, DISEC is an enormously influential committee of the UN, as it has been the driving force of international agreements relating to various issues such as the small arms trade, and the use of weapons of mass destruction. These feats of international cooperation can only be completed in such an assembly, which welcomes 193 member state delegates into an annual forum for discussion on pressing, world security issues.

DISEC offers the traditional Model United Nations experience for delegates of all experience levels. Position papers are recommended for this committee, but are mandatory for delegates to be considered for awards. Please read about CAHSMUN’s Position Paper policy, which can be found under the list of committees on the “Committees” page.
