A generation from now, schoolchildren will be shown the image of a drowned three-year-old lying face down on a beach.
They will look on in stunned silence, transfixed by this boy who could easily have been their little brother or a younger version of themselves. And their teacher will tell them how this tragic photo of lifeless Alan Kurdi sums up the historic global shame in 2015 as the international community failed to help millions of vulnerable people amid the worst refugee crisis since the Second World War.
It is up to world leaders – especially those in the largest and richest economies – to decide how this history lesson will end.
What will their legacy be for generations to come? Will they continue to shed crocodile tears while investing in fortifying their borders and ignoring the plight of millions of refugees? Or will they find their moral backbone and live up to their responsibility to assist those with a right to protection?
