The following is from a researcher whose specialty is “Death by Government”. He was nominated for a Nobel Peace Prize, and his research is a stark reminder as to why Reagan called the Soviet Union the “Evil Empire”. For all of those who rail against the US, please stop and actually absorb the magnitude of the numbers the author presents…
"Of course, eventhough systematically determined and calculated, all these figures and their graph are only rough approximations. Even were we to have total access to all communist archives we still would not be able to calculate precisely how many the communists murdered. Consider that even in spite of the archival statistics and detailed reports of survivors, the best experts still disagree by over 40 percent on the total number of Jews killed by the Nazis. We cannot expect near this accuracy for the victims of communism. We can, however, get a probable order of magnitude and a relative approximation of these deaths within a most likely range. And that is what the figures in Table 1 are meant to be. Their apparent precision is only due to the total for most communist governments being the summation of dozens of subtotals (as of forced labor deaths each year) and calculations (as in extrapolating scholarly estimates of executions or massacres).
With this understood, the Soviet Union appears the greatest megamurderer of all, apparently killing near 61,000,000 people. Stalin himself is responsible for almost 43,000,000 of these. Most of the deaths, perhaps around 39,000,000 are due to lethal forced labor in gulag and transit thereto. Communist China up to 1987, but mainly from 1949 through the cultural revolution, which alone may have seen over 1,000,000 murdered, is the second worst megamurderer. Then there are the lesser megamurderers, such as North Korea and Tito’s Yugoslavia.
Obviously the population that is available to kill will make a big difference in the total democide, and thus the annual percentage rate of democide is revealing. By far, the most deadly of all communist countries and, indeed, in this century by far, has been Cambodia under the Khmer Rouge. Pol Pot and his crew likely killed some 2,000,000 Cambodians from April 1975 through December 1978 out of a population of around 7,000,000. This is an annual rate of over 8 percent of the population murdered, or odds of an average Cambodian surviving Pol Pot’s rule of slightly over just over 2 to 1.
In sum the communist probably have murdered something like 110,000,000, or near two-thirds of all those killed by all governments, quasi-governments, and guerrillas from 1900 to 1987. Of course, the world total itself it shocking. It is several times the 38,000,000 battle-dead that have been killed in all this century’s international and domestic wars. Yet the probable number of murders by the Soviet Union alone–one communist country-- well surpasses this cost of war. And those murders of communist China almost equal it. "
