Genocides and campaigns of ethnic cleansing are regularly preceded by the kinds of political tactics described in this book. In the cases of Nazi Germany, Rwanda, and contemporary Myanmar, the victims of ethnic cleansing were subjected to vicious rhetorical attacks by leaders and in the press for months or years before the regime turned genocidal. With these precedents, it should concern all Americans that as a candidate and as president, Donald Trump has publicly and explicitly insulted immigrant groups.
