Hiroshima G7: Survivors urge leaders to prioritize nuclear disarmament.

As leaders of the Group of Seven (G7) nations gather in Hiroshima for a summit, many of Japan's "hibakusha" - atomic bomb victims whose average age is 85 - worry the summit may be a final chance to call for disarmament. They fear Hiroshima's legacy may be reduced to a historical artefact rather than a call for change. The venue has also highlighted a significant shift in global security since 2016, when Barack Obama became the first incumbent U.S. president to visit. For the West, Russia's Ukraine invasion has emphasised the importance of nuclear deterrence.
