Description

The United Nations is commemorating the eightieth anniversary of the atomic bombings of Hiroshima and Nagasaki, Japan, which took place on 6 and 9 August 1945, respectively. As we reflect on the devastation caused by nuclear weapons, this anniversary serves as a powerful reminder of the urgent need for global disarmament and the prevention of future nuclear conflict. 

The United Nations has long supported efforts to eliminate nuclear weapons through various treaties, resolutions and international cooperation. Its key initiatives include the Treaty on the Non-Proliferation of Nuclear Weapons and the Treaty on the Prohibition of Nuclear Weapons

Treaty on the Non-Proliferation of Nuclear Weapons

This treaty, which entered into force in 1970, aims to prevent the spread of nuclear weapons and technology, and to promote cooperation in the peaceful uses of nuclear energy. It also seeks to advance the goal of nuclear disarmament. 

Treaty on the Prohibition of Nuclear Weapons

This treaty, which entered into force in 2021, establishes the first legal framework specifically aimed at eliminating nuclear weapons. It prohibits the development, testing, production, acquisition and use of nuclear weapons. 

The United Nations also promotes disarmament through other initiatives, including the Comprehensive Nuclear-Test-Ban Treaty, and the Partial Test Ban Treaty. These treaties further contribute to the broader goals of the United Nations in preventing the spread of nuclear weapons and promoting nuclear disarmament. 

On this anniversary, the United Nations message to the world is to remember the lessons of these tragic events and recommit to a world free from nuclear weapons, emphasizing the importance of multilateralism, sustainable development and peace.
