Something we must never forget as well as Hiroshima terrorist bombing when the US is trying to give lessons of civilization to the rest of the world. They are the most barbaric nation that ever existed. It started with a genocide, developed thanks to slavery, and maintained through imperialism. They are the supreme caricature of what a few tiny European nations did to the world by colonizing all the planet.
Genocide is as old as history. It has been a part of the human condition from the very beginning. There are two main forms of genocide. One is direct genocide, a deliberate campaign to kill all members of an ethnic group. The second form of genocide is indirect genocide, which achieves the same result by seizing or destroying the land, the crops, the livestock and other essential items needed for survival. In World War II, for example, the Germans used both forms. Direct genocide took place in the gas chambers. Indirect genocide took place via programs like "Operation Hunger" where food was diverted from local Slav populations.
In the European conquest of North and South America both forms of genocide were also used although by far the predominant form of genocide was indirect genocide. A particularly horrible aspect of this tactic was the near extermination of the buffalo herds.
We do not know the exact number of people killed in the Americas. There was no one back in the time of Columbus compiling a census or doing a mass survey. However, we conclude that a figure of 75 million is reasonable.
A death toll of 100 million figure has been documented by the authors D.E. Stannard, author of American Holocaust, D.E. Stannard has said, "The destruction of the Indians of the Americas was, far and away, the most massive act of genocide in the history of the world." . And apparently it didn't take long for the Europeans to get this genocide started.
