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.
I'm gonna be honest here, this; I think that this is crank shit. You didn't have to go there, and you should know that the core premise here is literally not even correct; and everything that I have ever read about any real AES project tells me that they also know that. They just want Americans to stop fucking with their people & their internal development as a society, which they are correct to want.
I don't even disagree with your points about people "not being owed a middle-class lifestyle", and I do not give a shit about "Johnny America" and his projected guilt about whatever war-crimes he did. These are people that in a just world ought to face a revolutionary committee. But I don't agree that there's any value in buying into a framework of "Existential Struggle of Nations" weird-shit, even as a rhetorical device.
The comment's been removed, so you may not be aware, but they were the one who made the stakes "kill or be killed." I'm pretty sure I was even quoting them there.
If their argument is that it's ok for Americans to join the military and kill people abroad because otherwise they'll die, then that's the framework I'm going to respond to.
You can respond to it, by saying that it is in fact bullshit, and leaving it at that.
