The Disarmament and International Security Committee (DISEC), also known as the First Committee of the UN General Assembly, is responsible for addressing global peace and security challenges through disarmament, arms control, and regulation of emerging threats. Created in 1945 to prevent the devastation of another world war, DISEC has shaped major international treaties, including the Nuclear Non-Proliferation Treaty and the Arms Trade Treaty. While it cannot enforce binding measures like the Security Council, DISEC provides a vital platform for inclusive debate, consensus-building, and standard-setting among all UN member states. Today, the committee faces urgent issues such as the rapid development of autonomous weapons, cyber warfare, and advanced military technologies. Its work is critical in balancing national security with humanitarian concerns, ensuring that advancements in warfare do not outpace international law or ethical frameworks. DISEC remains central to fostering cooperation and preventing destabilizing arms races worldwide.
