It is impossible to imagine what Raphael Lemkin would be thinking and doing if he were alive today. He dedicated his life to stopping mass violence against people based on their identities and to holding those who were responsible accountable for their crimes. As a young man, he studied past slaughters, including pogroms against Jews, and he immersed himself in understanding the mass murder of the Armenians by the Turkish state, the failure to stop it, and to punish those who were responsible for it. In the midst of his efforts to draw attention to these issues, he lost 49 family members, including his parents, in the Holocaust. They died in the Warsaw ghetto, in concentration camps, and in the death marches.
