Amid rising geopolitical tensions and escalating nuclear rhetoric, UN Secretary-General António Guterres has urged nations to reinforce their commitment to the legally binding nuclear weapons treaty.
His call to action comes at a critical time when nuclear threats are becoming increasingly prevalent, raising global security concerns.
Speaking on behalf of the UN chief at the opening of the third Meeting of States Parties to the Treaty on the Prohibition of Nuclear Weapons (TPNW), Izumi Nakamitsu, High Representative for Disarmament Affairs, warned that “critical disarmament instruments are being eroded.” The meeting, taking place at the UN Headquarters in New York from March 3 to 7, aims to evaluate progress on nuclear disarmament and chart the treaty’s future course.
Nakamitsu expressed deep concern that the current geopolitical landscape, marked by unpredictable conflicts and rising tensions, could intensify public fear and reinforce the “false narrative” that nuclear weapons are “the ultimate provider of security.” She emphasized that the world must move away from this mindset and work towards a future free of nuclear threats.
Despite the prevailing challenges, there are signs of progress in global nuclear disarmament efforts. One major development is the increasing recognition of the catastrophic consequences of nuclear weapons, reflected in key international initiatives.
Nakamitsu highlighted the Pact for the Future, which focuses on achieving a nuclear-weapon-free world, and the awarding of the 2024 Nobel Peace Prize to the Japanese non-governmental organization Nihon Hidankyo for its unwavering commitment to nuclear disarmament.
Another positive step is the expanding membership of the nuclear weapons treaty. To date, 73 states have ratified or acceded to the treaty, and 94 have signed it, demonstrating broad international support for the initiative. Additionally, the treaty has fostered strong engagement with civil society and the establishment of a scientific network dedicated to providing evidence-based research on nuclear disarmament.
This week, government representatives, international organizations, and civil society groups are convening at the UN to prepare for the treaty’s first review conference and discuss the next phase of its implementation.
The meeting will include panel discussions and debates on pressing nuclear disarmament issues, including the risks of nuclear conflict, humanitarian consequences, security concerns, victim assistance, and environmental remediation. Before the session concludes on Friday, delegates are also expected to adopt a political declaration reinforcing their commitment to the treaty.
Legally Binding Treaty and Its Objectives
The Treaty on the Prohibition of Nuclear Weapons, which was adopted on July 7, 2017, and entered into force on January 22, 2021, is the first multilateral nuclear disarmament agreement negotiated in over two decades.
At the time, the UN Secretary-General hailed it as “an important step towards the goal of a world free of nuclear weapons and a strong demonstration of support for multilateral approaches to nuclear disarmament.”
The treaty imposes a comprehensive ban on all nuclear weapon-related activities. This includes prohibitions on the development, testing, production, acquisition, possession, stockpiling, and use of nuclear weapons. It also explicitly forbids the deployment of nuclear weapons on national territory and prohibits states from assisting others in engaging in such activities.
In addition to banning nuclear weapons, the treaty outlines obligations for states to assist victims affected by nuclear weapon use or testing. It also requires nations to take measures to remediate environmental damage caused by nuclear activities in areas under their jurisdiction or control.
The urgency of nuclear disarmament has never been more pronounced. With nuclear threats resurfacing in global conflicts and critical arms control agreements under strain, the need for collective action is paramount. The UN continues to advocate for strengthened international cooperation to ensure that nuclear weapons are never used again.
