Earlier quoted context omitted.
The US and Germany are allies. In fact, I believe “German” is the largest ancestry group in the US. Besides which, it’s extremely common for entities to invest in mutually beneficial agreements with other entities.
This idea that policy should be set based on a grossly oversimplified wrapping up of a huge surface area of agreements into the term "ally" and vague notions of ethnic similarity needs to die. It gives the ruling class a mechanism to excuse war crimes of our supposed "allies" and drop bombs on supposed "enemies" for perceived minor infractions.
But I think it’s the quality of response the parent deserved, given their ridiculously hyperbolic framing of “a foreign occupying force”.
