There is no number of foreigners that is unacceptable to sacrifice for a middle class livelihood. Anti-cop because they can imagine a scenario where a cop inconveniences them. These principles don't apply to the Waffen SS because they can't imagine a soldier personally inconveniencing them and, of course, foreigners aren't really humans.
It makes sense then, conscripts tend not to want to die for the empire for little to no gain.
Thanks for the information
should also be considered that a lot of american 'volunteers' arent true volunteers, they join the military because theyre in the middle of nowhere with zero education and want a way out and its a purely economic decision. most dont expect to have to terrorize children. one guy i know just sat in a car near the border playing on a gameboy seeing if there were any cartel drones flying around. said he detected a single one in his entire career
