Thursday marked the 81st anniversary of the atomic bombing of Hiroshima.

Prime Minister Sanae Takaichi attended commemorations in the city, as should every Japanese prime minister and representative of the diplomatic community in this country. There is no more compelling reminder of the inhumanity of atomic weapons and the need to ensure that they are never used again than the Hiroshima Peace Memorial Park.

Incredibly, that lesson is in need of learning. Governments around the world seem to be reassessing the value of nuclear armaments, seeing new utility in them, prompting states with those capabilities to develop and refine them while spurring others to consider their acquisition. Meanwhile, international architecture that restrains or prevents their spread is deteriorating.
