Here’s a good watch for you hawk. Details how it never really happened.
There were certainly camps under German control for all sorts of people identified (rightly or wrongly) as threats to Germany (a la FDR's Japanese Internment program). They were certainly put to work for the war effort (FDR did this as well with regard to Japanese Americans). Many people certainly died under poor conditions from various causes in the German camps, the vast majority of whom during the last months of the war. It was undoubtedly a massive tragedy, one among many such tragedies that occurred in all areas of the world affected by WWII.
