Disarmament and International Security Committee
Double Delegation
Topic A: Nuclear Non-Proliferation and Preventing Nuclear Escalation
Topic B: The Use of Unmanned Aerial Systems in Modern Warfare
In a world where geopolitical tensions and military capabilities continue to evolve, the threat of nuclear proliferation and the risk of nuclear escalation have become critical to address. While nuclear technology has the potential to provide clean energy and scientific advancement, the continued spread and modernization of nuclear weapons threaten international peace and security. Today, both nuclear and non-nuclear states are faced with pressing issues such as weakening arms control agreements, regional conflicts involving nuclear powers, the emergence of new nuclear states, and the growing risk of miscalculation that could escalate into catastrophic conflict.
While nuclear proliferation remains one of the most enduring challenges to global security, the rapid development of unmanned aerial systems has transformed the landscape of modern warfare. From intelligence gathering and precision strikes to autonomous operations, these technologies have reshaped military strategy while raising significant legal, ethical, and humanitarian concerns. As drones become increasingly accessible to both state and non-state actors, the international community must address issues including civilian protection, accountability, cross-border sovereignty, and the lack of comprehensive international regulations governing their use. As DISEC works to develop effective strategies across both topics, delegates must collaborate to draft resolutions that strengthen global non-proliferation efforts, reduce the risk of nuclear escalation, and establish responsible international frameworks for the use of unmanned aerial systems in modern warfare.
Esteemed Delegates,
It is my pleasure to welcome you all to the Disarmament and International Security Committee (DISEC) for the 2027 session of Harvard Model United Nations. I am honored to serve as your Director, and I look forward to working with all of you over the course of this conference.
My name is Sarina Harjani. I was born and raised in Chicago, Illinois, and I am currently a sophomore at Harvard. I study Government and Sociology, and I plan to attend law school after college. Model United Nations has been a significant part of my life since my freshman year of high school, and I am grateful to have the opportunity to continue this activity in college. At Harvard, I both compete and am on leadership for the Intercollegiate Model United Nations (ICMUN) team. This past year, I was also a Director for HMUN Canada, India, and Dubai, and I served as an Under-Secretary-General for HMUN Dubai and HNMUN. Outside of Model United Nations, I am a member of Harvard’s Institute of Politics and Undergraduate Women in Law Association, and I enjoy playing tennis and pickleball in my free time.
Outside of Model UN, I often seen on the pickleball courts, ordering iced coffee at Blank Street, or laughing nonstop with her friends. I cannot wait to meet everyone in January! Please do not hesitate to reach out with any questions or concerns. Good luck!
Sincerely,
Sarina Harjani
Director, Disarmament and International Security Committee
