Sunday, April 24th marked the 90th anniversary of the first genocide of the twentieth century: the Turkish government's slaughter of over a million unarmed Armenians. The key word is "unarmed." The Turks got away with it under the cover of wartime. They suffered no greater postwar reprisals for this act of genocide than if they had not conducted mass murder of a peaceful people. Other governments soon took note of this fact. It seemed like such a convenient international precedent.
