My grandma Sadie lived in the town of Droghobych in Ukraine until she was 13. Nearby, there is a dirt road through a forest leading to the mass graves where the town’s last Jewish population lies buried. It is barely marked — if you did not know to look for the large slabs of concrete between the trees, you would have a hard time finding it. As a human rights lawyer who has spent a lifetime documenting atrocities, I was not prepared for the effect of this visit a few months ago. I broke into tears.
