Ever heard of typhoid? It’s transmitted through lice and was a huge issue towards the end of WWI until after WWII. You could imagine that typhoid would be a huge issue in POW camps. Gas chambers? More like fumigation rooms for mattresses and bedding. Zyklon B was a pesticide and was used in the “gas chambers”. That pesticide wasn’t potent enough to kill people in under an hour, yet we are supposed to believe that they used it to kill 6 million Jews in a relatively short period of time? Oy vey.
