248 Nor must we forget the atomic bombs dropped on Hiroshima and Nagasaki. Once again, “I pay homage to all the victims, and I bow before the strength and dignity of those who, having survived those first moments, for years afterward bore in the flesh immense suffering, and in their spirit seeds of death that drained their vital energy… We cannot allow present and future generations to lose the memory of what happened. It is a memory that ensures and encourages the building of a more fair and fraternal future”. Neither must we forget the persecutions, the slave trade and the ethnic killings that continue in various countries, as well as the many other historical events that make us ashamed of our humanity. They need to be remembered, always and ever anew. We must never grow accustomed or inured to them.
