The Disarmament and International Security Committee (DISEC) is the First Committee of the United Nations General Assembly. DISEC deals with transnational security issues, including threats to peace and conventional arms control. The committee’s primary goal is to foster international cooperation, playing a pivotal role in the formation of international treaties regarding arms control and disarmament. Delegates of DISEC will address threats to the freedom of civilians and cooperate to maintain peace and order. 

DISEC is a General Assembly that is open to all delegates, regardless of experience. Both committee topics use Regular Rules of Procedure. Although position papers are not mandatory for this committee, they are required in order to be eligible for an award.

Questions, inquiries, and position papers for this committee can be emailed to disec@cahsmun.org.

Minh Dang Tran | Co-Director

Reaching the end of his four-year journey in Model United Nations, Minh is honoured to serve as Co-Director for DISEC at the 23rd iteration of CAHSMUN. Initially, MUN was a small stint to enhance his public speaking skills, but it has since grown into a thriving community where Minh has found countless irreplaceable friendships. From decriminalizing the use of cannabis in his first conference to uniting the Valorant world as Katseye in crisis, he discovered a passion for the silly yet diplomatic duality that is MUN. Inside his undercover life, Minh is often found continually falling ranks in Identity V, to his dismay, and constantly pondering all the work he will not do tomorrow. What he will do, however, is strive to ensure that every delegate finds the same passion, growth, and friendships that he has at CAHSMUN 2027.

Yugo Tsao | Co-Director

Entering his grade 10 year at St. Georges School, Yugo is excited to be serving as one of the co-directors of DISEC for CAHSMUN 2027. 3 years ago, Yugo's MUN journey began as a nervous grade 7 student who knew almost nothing about the world around him. Now he understands a little more (not really) and will do his best to make this conference memorable for all of his delegates at DISEC. Due to his love for socializing, Yugo loves seeing all of the meaningful debate and fascinating discussions that happen during committee sessions. Outside of the committee room, you can find Yugo munching down on whatever food looks good, playing Tom Clancy's Rainbow Six Siege, or hanging out with his friends. Yugo wishes all of you a productive and memorable conference, and cannot wait to see you all at CAHSMUN!

Aileen Jiang | Chair

Entering her 10th grade year at Crofton House School, Aileen is excited to serve as the Chair of DISEC at CAHSMUN 2027. Her first MUN speech, though drawn from a round table, introduced an undeniable passion for voicing her opinions in committee. Today, she no longer nervously counts down the speakers before her in a round table; though, the same dedication to enhance committee discourse remains. Heated debates and the friendships that follow have made Model UN an irreplaceable passion of Aileen’s. Beyond the Sheraton, Aileen can be found pushing the boundaries of her dynamic balance, meticulously picking out filler words from her debate case, or testing the newest punny joke with all her contacts. She hopes CAHSMUN 2027 will be an unforgettable experience for all involved.

Paul Holland | Chair

Now in his fifth year of Model UN, Paul is honoured to serve as chair for the first time in DISEC. Since his first experience with Model UN, Paul has grown to love it and has participated in several conferences, though he will never stop putting off his position papers until the last minute. Outside of committee sessions, he can be found watching movies, listening to music, and generally trying to ignore the impending deadlines for his schoolwork. He is eager to welcome this year’s delegates to CAHSMUN, whether they’re completely new to MUN or seasoned veterans. Either way, he can’t wait to experience this year’s conference and to provide a memorable experience for everyone in attendance!
