Clearly you know little but think you know much, because you may have seen much propaganda misinformation.

The number of people who died (were NOT killed) was about 200,000. Not just Jews. That's still a fuck tonne, admittedly, as you see in the propaganda photos and movies taken by what became famous Hollywood directors. They died from typhus and starvation, as did Germans, because their supply lines were cut off, they had no fucking fuel to transport food much less burn 6m bodies nor properly defend themselves in the war. Those were SLAVE camps, not death camps. The US was worse with their prisoners (if they bothered to let them live) and their concentration camps.
