Conclusion

Hiroshima is no city, it is the global conscience – the reminder of the power that should not be dared, and weapons that allow scientific development at the service of killing. With the world on the brink of new threats of nuclear attacks and the political instabilities, Hiroshima is calling on countries to turn to peace instead of power, disarmament instead of deterrence and remembrance instead of amnesia
