Remembering Hiroshima: annual commemoration, 6th August 2026

This year we will mark the 81st anniversary of the Hiroshima bombing, which took place on 6th August 1945. Irish CND will be holding the customary annual commemoration in Merrion Square in Dublin. 

There will be short speeches by Lord Mayor of Dublin Daryl Barron, Japanese Counsellor and Deputy Head of Mission in Ireland, Mr Koji Hirohata, and Afri Board member, Dr Patrick Bresnihan (Maynooth University). There will also be contributions of music and poetry, and a wreath of flowers will be laid at the tree at the close of the commemoration. Both Irish CND and Afri are members of the International Campaign to Abolish Nuclear Weapons (ICAN, Nobel Peace Prize laureate in 2017), so it is very fitting that both organisations are involved in the commemoration this year. 

An estimated 80,000 people were directly killed by the bomb dropped on Hiroshima, with casualties reaching 140,000 within a year. Approximately 12,500 nuclear weapons remain in the world today, more than enough to destroy life on earth as we know it many times over.

Sadly, the dark shadow of the possibility of nuclear war looms more grimly than perhaps ever before. Spending on nuclear weapons reached more than $119 billion last year, a shocking new high, with more than half of this expenditure deriving from the United States. The last nuclear arms control treaty between Russia and the United States was allowed to expire in February 2026. Nuclear weapons states are all engaged in modernising their arsenals and delivery systems. Five of the nine nuclear-armed states have engaged in international military attacks in the past year alone. It would only take a moment of madness to plunge the world into an irreversible nuclear war.

We must meet darkness with the light of positive hope and determination. We look forward to welcoming as many of you as possible to our commemoration in Merrion Square, remembering over eight decades of solidarity in the face of nuclear destruction. Wherever you are, even if you are not in a position to join us in person this year, please do join us in spirit to stand in solidarity with the victims of these horrific weapons of mass destruction, and to affirm our determination to work for their elimination, the only way to ensure that the ghastly events of Hiroshima and Nagasaki will not be repeated. 

Witness and warnings: will the world's leaders listen?

As the 80th anniversary of the Hiroshima and Nagasaki bombings passed in 2025, the voices and of the survivors of the attacks - the hibakusha (literally, explosion-affected people) bore powerful and tragic testimony to the unthinkable humanitarian cost of nuclear weapons. 

In Ireland, Irish CND and Afri (both members of ICAN, the International Campaign to Abolish Nuclear Weapons) were privileged to host Kyoko Gibson, a second-generation hibakusha from Hiroshima, now living in Wales. Kyoko spoke eloquently at a number of events, including a secondary school visit, student talks in TCD and TUD, and an open meeting in the Quaker meeting house in Dublin city centre. She also visited Leinster House to meet with John Lahart TD, chair of the Oireachtas committee on Foreign Affairs. 

She described her experiences as a child growing up in the aftermath of the bombing in Hiroshima, and her involvement in the campaign for world peace and the abolition of nuclear weapons, in a deeply moving plea to support and continue her campaigning work.

Kyoko Gibson's address to the No More Hiroshimas event in Trinity College, co-hosted by the School of Religions, Theology and Peace Studies, can be viewed here, along with responses from Prof. Iain Atack and Dr David Hutchinson Edgar, representing Afri and Irish CND. 

The message shared with us by Kyoko Gibson, in common with that of other hibakusha, speaks of the utter depravity of such weapons of mass destruction, and the unspeakable horrors of their lasting impact on those affected. 

The bomb dropped on Hiroshima in 1945 was small compared with the destructive capacity of today's nuclear arms, even the so-called "tactical" weapons in the arsenals of the United States and Russia. The catastrophic humanitarian and environmental effects of any use of a nuclear weapon today do not bear thinking about. As the International Committee of the Red Cross / Red Crescent has pointed out, the destruction of medical and other infrastructure in a nuclear attack would make it impossible to have any kind of organised aid response in the attack's aftermath. The consequent suffering would be enormous. 

More than eighty years on, the world faces a polycrisis of war, climate change, biological threat and technological disruption, as noted by the Bulletin of Atomic Scientists in setting the Doomsday Clock at 85 seconds to midnight, symbolically the closest it has ever been to apocalypse. 

With Russia, the United States, and Israel all involved in international conflict, and cross-border exchanges between India and Pakistan - all nuclear-armed states - in the past year, it is clear that nuclear weapons do not prevent wars or bring stability to the international order. The presence of nuclear weapons in a volatile and unstable world increases the risk of annihilation. 

The witness and warnings of the hibakusha, and of international medical, humanitarian and scientific experts, must be listened to with renewed acuity. It is our responsiblity to magnify their voices and their testimony to a level that can no longer be ignored by world leaders: No More Hiroshimas.
