Disarmament and International Security Committee

From fast-paced conflict resolution to revolutionary policy changes, the Disarmament and International Security Committee lies at the forefront of the United Nations General Assembly. As the first committee of the General Assembly, DISEC addresses conflicts and threats to international peace and tries to maintain global stability and security. Although its resolutions are non-binding, DISEC’s efforts are highly influential and often lay the groundwork for resolutions in other committees of the United Nations. The vast membership of DISEC makes it an especially important organ for dealing with issues of an international scope.

As this committee is designed for both beginners and experienced delegates alike, delegates of all abilities are welcome. Position papers, although strongly suggested, are not required. However, delegates must submit position papers by January 7 to be considered for an award.

Sean Lee | Director

Sean is currently a grade 12 student at St. George’s School, and is delighted to be serving as your director for DISEC at VMUN 2018. Directing DISEC signifies a full circle moment for Sean, as he represented Portugal in this very committee at VMUN 2014, his first ever Model United Nations conference. Since then, Sean has attended a plethora of conferences as a delegate and as a staff member, and has developed a considerable passion for MUN throughout. In his spare time, Sean enjoys debating, attempting to conjugate Latin verbs, and of course, creating not-so-dank memes. Sean is more than excited for a weekend full of fruitful debate and collaboration, and looks forward to making VMUN an enriching and enjoyable experience for all of his delegates!

Sarah Buddhason | Assistant Director

Sarah is a junior at Moscrop Secondary School and is thrilled to serve as the Assistant Director of the Disarmament and International Security Committee. Having participated in Model UN over the span of two years, she has grown to love the intensity of debate and the cooperation needed to resolve pressing global issues. When not studying for an exam, you can often find her involved in numerous projects dedicated to promoting equity in STEM. Outside of MUN, she can be found playing her alto saxophone, buying overpriced coffee, clarifying what her ethnicity is, and starting new shows she’ll never finish. Sarah is looking forward to a conference filled with lively debate, communication, and compromise, and is certain that VMUN 2018 will be a wonderful experience for all delegates!
