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.

Peter Jiang | Director
Peter Jiang is currently a grade 11 IB student at Semiahmoo Secondary. When he isn't out flying gliders or mastering the delicate art of baking, he can be found crying over his massive workload and
laminating his notes so the tears can roll off. He is also passionately and deeply involved in the world of Model United Nations and debating, as he pours what is left of his free time into managing
his school club. Having gone to his first conference in grade 9, there has yet to be a conference that he has regretted attending. Whether it is your first conference or your last, he can assure you that CAHSMUN 2017 will be a spectacular experience. Peter looks forward to a weekend full of heated and enchanted debate.

Julian Miller | Chair
Julian Miller is a junior at Prince of Wales Secondary, and is honoured to have been given the opportunity to chair DISEC at CAHSMUN 2017. It has been four years since Julian first stepped into the world of Model UN, and he has enjoyed every moment of it since. Though he has attended many conferences, there has never been a committee that has failed to enthrall him, and he is certain that DISEC will be no different in this regard. In his free time, Julian can be found playing tennis, watching soccer, or listening to Kanye West. He is sincerely looking forward to meeting delegates, and doing his very best to facilitate an outstanding committee experience for beginners and experienced delegates alike.
