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.
...and living in abject poverty, the material conditions between those soldiers that led them to a revolution aren't even close to US soldiers who are doing it for slightly more comfortable middle class lifestyle.
really depends on ethnic background and other factors though.
