It seems astonishing that, even after the Holocaust of the 1930s-40s, there could have been further genocides. Is it that people fail to recognise the warning signs that lead to such atrocities? Or that they lack the power and protection to stop the descent into barbarity?
The lesson is that human rights must be defended early and often. We should and we must defend our rights against even the tiniest encroachment. If we do not, whoever has violated those rights will surely return to erode them further.
