As shown on this web site (e.g., see Table 1.2 of Death By Government), from 1900 through 1987 governments murdered near 170,000,000 people. With respect to this figure I am often asked how much of this occurred since the end of World War II in 1945. With the conclusion of that war and the discovery of the breadth and depth of the Holocaust, many demanded "Never Again." But our history since has rather been: "Again, again, again, and again."
