Upwards of 80 million people died in World War II. 52 million of these were civilians, 20 million of whom died of disease or famine. Of the 30 million soldiers who died, 5 million died in prisoner-of-war camps.
In the Soviet Union alone there were 23 million deaths, 10 million of which were military personnel. In China, there were 20 million deaths, 4 million of them soldiers.
Six million Jews were killed. They were first transported to forced labor camps, then sent to the gas chambers. The fact that 6 million Jews died is not all that consequential, given the above numbers. It’s how they died that’s a big deal.
There are a lot of extenuating circumstances. There are no and never will be any excuses, just relevant issues.
It’s not as if the Jews were suddenly swept away and killed. The Nazis had singled them out for discrimination for almost twenty years, ever since the Great Depression. Jews had long since lost their jobs, their wealth, their professions, everything. Their roots in Germany were not that deep.
