Interesting, I imagine the propaganda was also used for the German public, because they had no idea they were death camps.
Israel would doubtless keep its genocide a secret if it could, but there's just so much evidence created by smartphones. This is actually an example of how technology is making the world a massively better place--it's so much harder to genocide without creating tons of evidence.
“The Germans wanted a propaganda tool for [SS] visitors and camp newsreels and a tool to boost camp morale.”
There were also several men’s orchestras.
