I'll let the more German members of the board jump in, but as the guy with the accent but grew up in America I can understand why. Blaming Jews has been illegal for decades. It took me a while to realize my cousins had the same games as I did because they were battling robots and nutcrackers while I was shooting them.

If I raised my hand enthusiastically at the wrong angle my teacher flinched.

So yeah, it can't be Israel because that would mean Skynet is behind it all.
