The 20th anniversary of the Rwandan genocide offers an opportune moment to reflect on the horrific events of 1994, and honor the countless victims and survivors who still carry the collective trauma of mass murder. Remembering these deliberate efforts to extinguish an entire ethnic community should not only give us pause, but also encourage our atrocity prevention community, including humanitarian and peace organizations around the world, to rethink how such failures of humanity can guide us forward, beyond «Never Again» slogans.
