FORUM: "Designing a World without Nuclear Weapons" International Day for Disarmament and Non-Proliferation Awareness 2026. The observance seeks to promote better awareness and understanding of disarmament issues among the public, especially young people. Since the founding of the United Nations, the goals of multilateral disarmament and arms limitation have been central to the Organization’s efforts to maintain international peace and security. Weapons of mass destruction, in particular nuclear weapons, continue to be of primary concern, owing to their destructive power and the threat that they pose to humanity. The excessive accumulation in conventional weapons and the illicit trade in small arms and light weapons jeopardizes international peace and security and sustainable development, while the use of explosive weapons in populated areas is seriously endangering civilians. New and emerging weapon technologies, such as autonomous weapons, pose a challenge to global security and have received increased attention from the international community in recent years.

The United Nations General Assembly has held three Special Sessions on Disarmament (SSOD), which fundamentally shaped the disarmament architecture and the subsequent discussions within it. Despite repeated calls since 1995, including recently in the Pact for the Future, a fourth special session remains elusive. This event examines the lasting impact of these sessions and explores a critical question: can the international community overcome current divisions to convene SSOD-IV?

Suzuka Nakamura, a Japanese peace activist and third‑generation hibakusha (atomic bomb survivors) from Nagasaki, has been advocating for a world free of nuclear weapons since high school. Selected as one of the UN Youth Office's 17 Young Leaders for the Sustainable Development Goals (SDGs) for 2025-2027, she is now determined to create a mobile atomic bomb museum as a new way to bring the urgent call for nuclear disarmament to communities across the world.
Our dream of peace is in peril.
The threat of nuclear weapons use is the highest in decades. Global tensions are pushing military spending to stratospheric levels. Small arms and light weapons are proliferating. And emerging technologies are making conflicts even deadlier.
We must lower the temperature. On this International Day for Disarmament and Non-Proliferation Awareness, I urge leaders to step back from the brink. Stop rattling the nuclear saber. Halt the arms races.
It’s time to invest in the architecture of peace, not the tools of war. That means living up to disarmament obligations. Rebuilding trust. And strengthening the systems and tools that prevent the proliferation, testing and use of deadly weapons.
Together, we can prevent catastrophes and ensure a safe and peaceful world for all.
António Guterres, United Nations Secretary-General.
